As an application, we extend our algorithm to compute a robust minimum s-t cut, that is, a conservatively chosen minimum s-t cut in light of data uncertainty.

Two main families of axiomatically based risk measures are the coherent risk measures, which assume subadditivity for random variables, and the insurance risk measures, which assume additivity for comonotonic random variables. We propose new, data-based, risk measures, called textit{natural risk statistics}, that are characterized by a new set of axioms. The new axioms only require subadditivity for comonotonic random variables,  consistent with the prospect theory. We point out while many risk measures may be suitable for internal risk management, robustness is an important consideration for external risk measures. Comparing to the previous measures, the natural risk statistics include the tail conditional median which is more robust than the tail conditional expectation suggested by coherent risk measures; and, unlike insurance risk measures, the natural risk statistics can also incorporate scenario analysis. The natural risk statistics includes VaR as a special case and therefore shows that VaR, though simple, is not irrational.\n\u003C\/p\u003E\n\u003Cp\u003E(Joint work with Chris Heyde and Xian Hua Peng) \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Professor Steve Kou, Industrial Engineering and Operations Research, Columbia University, will give a presentation on, \u0022What Is A Good External Riskj Measure: Bridging the Gaps Between Robustness, Subadditivity, and Insurance Risk Measures.","format":"limited_html"}],"field_summary_sentence":[{"value":"QCF Seminar:  What Is A Good External Risk Measure"}],"uid":"27279","created_gmt":"2009-10-12 21:20:27","changed_gmt":"2016-10-08 01:47:58","author":"Barbara Christopher","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-03-24T12:00:00-04:00","event_time_end":"2008-03-24T13:00:00-04:00","event_time_end_last":"2008-03-24T13:00:00-04:00","gmt_time_start":"2008-03-24 16:00:00","gmt_time_end":"2008-03-24 17:00:00","gmt_time_end_last":"2008-03-24 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"1191","name":"industrial engineering"},{"id":"564","name":"operations research"},{"id":"6009","name":"qcf seminar"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EHarry Sharp\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:bin2007@isye.gatech.edu\u0022\u003EContact Harry Sharp\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-6545\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"43874":{"#nid":"43874","#data":{"type":"event","title":"DOS Optimization Seminar: Ellis L.

Measuring and monitoring the traffic on such high-speed links has become an ever challenging problem. Our team is among the first to realize that data streaming algorithms have the potential to become very useful tools for measuring and monitoring high-speed networks. Data streaming is concerned with processing a long stream of data items in one pass using a small working memory in order to estimate certain statistics of the stream. The challenge is to use this small memory to \u0022remember\u0022 as much information pertinent to this estimation as possible. However, existing data streaming algorithms are typically designed for processing a single stream of data for a single type of statistic, and most of these algorithms cannot operate at very high link speed. Targeting the deficiency of existing approaches, we have investigated new data streaming paradigms and mechanisms that allow us to perform large-scale distributed data streaming on tens of thousands of high-speed links and nodes, and aggregate, compress, and interpret these streaming results, for better measurement and monitoring of large networks. We also discovered that the applications of data streaming go far beyond network measurement and monitoring. Recently, we have successfully applied the data streaming techniques to a seemingly unrelated area: query routing in an unstructured P2P network. In this talk, I will talk about these new applications as well as our theory of formulating the data streaming problems in CS as the channel design problem in EE. \n\u003C\/p\u003E\n\u003Cp\u003EBIOGRAPHY:\u003Cbr \/\u003E\n\u003Cstrong\u003EJun (Jim) Xu\u003C\/strong\u003E is an Associate Professor in the College of Computing at Georgia Institute of Technology.

We are interested in the tail decay behavior of its marginal distributions in the steady state. We solve this problem by characterizing the decay rates as the solutions of a certain non linear optimization problem, provided the stationary distribution exists. In general, those decay rates are in the logarithmic sense, referred to as weak decay rates. However, this result with help of existence results also answers to the question when the asymptotic decay is exactly geometric and what happens if it is not the case. We exemplify these results for Jackson networks and their modifications.\n\u003C\/p\u003E\n\u003Cp\u003E============================================================\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EDavid McDonald\u003C\/strong\u003E, University of Ottawa\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003EA Stochastic Model for the Throughput of HTTP sessions\u003C\/em\u003E\n\u003C\/p\u003E\n\u003Cp\u003EWe introduce a simplified model of an HTTP which consists of a succession of idle and download periods. The file downloads are subject to a fixed packet loss probability. The same TCP connection is used for the download of a random number of files. We assume the files are transmitted in the congestion avoidance regime and we don\u0027t consider time outs. We do take into account the effect of slow start at the beginning of a download period with SSTHRESH set to CWND after the last loss in the preceeding download period; i.e. the cycles are dependent. For this stochastic model, we derive a closed form formula for the stationary throughput obtained by a flow. We also derive closed form expressions for the mean time to transfer a file and for the distribution of the throughput. We also briefly discuss how the formulas can be applied to predict bandwidth sharing among competing HTTP flows.\n\u003C\/p\u003E\n\u003Cp\u003E============================================================\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ESunil Kumar\u003C\/strong\u003E, Stanford University.\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003EDynamics of New Product Introduction in Closed Rental Systems\u003C\/em\u003E\n\u003C\/p\u003E\n\u003Cp\u003EWe study a rental system where a fixed number of heterogeneous users rent one product at a time from a collection of re-usable products.

The first part is about a hyper-exponential jump diffusion model for option pricing. The main objective is to extend the analytical tractability of the Black-Scholes model to alternative models with jumps, no matter whether the jump sizes have exponential-type tails or power-type tails. More precisely, we study a jump diffusion model for asset prices whose jump sizes are hyper-exponentially distributed. The hyper-exponential distribution can approximate most heavy-tail distributions as closely as possible, including both power- and exponential-type distributions. We demonstrate the hyper-exponential jump diffusion model can lead to analytical solutions for popular path-dependent options such as lookback, barrier, quantile, and perpetual American options. Numerical examples indicate that the formulae are easy to implement and accurate. These analytical solutions are made possible mainly because we solve several high-order integro-differential equations explicitly related to first passage time problems and optimal stopping problems.\n\u003C\/p\u003E\n\u003Cp\u003EIn the second part, we propose a two-factor equilibrium model for electricity spot and futures prices.

The research is built on the work on model-robust design of Li and Nachtsheim (2000) and model-discriminating designs of Jones, Li, Nachtsheim, and Ye (2007, 2008). We introduce new criteria for model discrimination and use these and existing criteria to evaluate standard orthogonal designs. We also use these criteria to construct optimal two-level designs for screening experiments. Results indicate that, for a given sample size and number of desired factors, not all orthogonal designs are model-discriminating designs for the model spaces considered. We conclude with some simulation studies, which show that the proposed designs can lead to a higher probability of identifying the correct model in the data analysis procedure than traditional minimum aberration designs. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Professor William Li, Operations and Management Science Department, University of Minnesota will present a lecture on model-robust and model-discrimination design.","format":"limited_html"}],"field_summary_sentence":[{"value":"Model-Robust and Model-Discriminating Designs"}],"uid":"27279","created_gmt":"2009-10-12 21:20:32","changed_gmt":"2016-10-08 01:47:58","author":"Barbara Christopher","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-02-26T10:00:00-05:00","event_time_end":"2008-02-26T11:00:00-05:00","event_time_end_last":"2008-02-26T11:00:00-05:00","gmt_time_start":"2008-02-26 15:00:00","gmt_time_end":"2008-02-26 16:00:00","gmt_time_end_last":"2008-02-26 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6018","name":"model-discrimination design"},{"id":"6017","name":"model-robust"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EXiaoming  Huo\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:xiaoming.huo@isye.gatech.edu\u0022\u003EContact Xiaoming  Huo\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-385-0354\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"43882":{"#nid":"43882","#data":{"type":"event","title":"Faculty Candidate Seminar:  Itay Gurvich","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EFaculty Candidate:\u003C\/strong\u003E Itay Gurvich\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EPresentation Title:\u003C\/strong\u003E Service-level differentiation in large-scale service systems \n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EAbstract\u003C\/strong\u003E: Motivated by telephone call centers, we study the problem of service-level differentiation in largescale service systems with multiple customer classes and multiple agent pools. Call Centers usually specify their operational objectives through the x-y service-level (SL) constraint, which stipulates that x% of the calls should be answered within y seconds. Typically, service-level differentiation is imposed through different SL objectives for different customer classes. In order to achieve these constraints a Call-Center needs to determine the types of agents that will be used (Design), the number of agents of each type (Staffing) and the real-time control to be used (Routing). We propose a solution based on a family of routing controls called Fixed-Queue-Ratio (FQR) rules. In many settings, FQR allows us to solve the combined Design-Staffing-and-Routing problem in a nearly optimal way. Our analysis also establishes a diminishing-returns property of flexibility by showing that,under FQR, very moderate cross-training is sufficient to make the call center work as efficiently as a single-pool system.

I use differential equation and network simulation models to estimate the costs and effectiveness of various screening and contact tracing strategies, and I use optimization to determine the optimal disease control strategy (for example, the optimal allocation of resources between screening and contact tracing).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003EEvent Contacts:\u003C\/em\u003E Paul Griffin (and Julie Swann)\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"ISyE Faculty Candidate Seminar:  Benjamin Armbruster","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Faculty Candidate Seminar:  Benjamin Armbruster"}],"uid":"27279","created_gmt":"2009-10-12 21:20:32","changed_gmt":"2016-10-08 01:47:58","author":"Barbara Christopher","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-02-28T10:00:00-05:00","event_time_end":"2008-02-28T11:00:00-05:00","event_time_end_last":"2008-02-28T11:00:00-05:00","gmt_time_start":"2008-02-28 15:00:00","gmt_time_end":"2008-02-28 16:00:00","gmt_time_end_last":"2008-02-28 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.stanford.edu\/~barmbrus\/","title":"Benjamin Arbruster"}],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6016","name":"Benjamin Armbruster"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJennifer Harris\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:jharris@isye.gatech.edu\u0022\u003EContact Jennifer Harris\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"43826":{"#nid":"43826","#data":{"type":"event","title":"Faculty Candidate Seminar: Judy Jin","body":[{"value":"\u003Cp\u003E\u003Cem\u003ESpeaker:\u003C\/em\u003E \u003Cstrong\u003EJudy Jin\u003C\/strong\u003E, University of Michigan, Department of Industrial and Operations Engineering\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003ETitle:\u003C\/em\u003E  \u003Cstrong\u003EData Fusion for Quality Improvements in Complex Systems\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003EAbstract:\u003C\/em\u003E\u003Cbr \/\u003E\nOur current data rich environment provides unprecedented opportunities and research challenges for improving complex system operations both in manufacturing and in service industries. The development of a novel data fusion methodology is currently very relevant, and will provide a long lasting future impact.  Efforts in data fusion research have significantly advanced the development of methodology in areas like rapid change detection, root cause diagnostics, and system control.  Data fusion, through integrating engineering domain knowledge with data analysis techniques from advanced statistics, signal processing, decision making, and system control, represents one of the frontiers in quality improvement research for complex systems.\n\u003C\/p\u003E\n\u003Cp\u003EThis presentation will provide an overview of ongoing data fusion research for manufacturing system improvement and its extension to service industry applications. The basic concepts in data fusion research will be discussed, with emphasis placed on promoting the integration of disparate methodologies into a cohesive entity to enable effective decision-making for system operations. Examples of methodological developments and their applications will be discussed in order to demonstrate the characteristics of data fusion research and to emphasize the need for  multidisciplinary system integration efforts.  Detailed discussions will focus on an example of a model-free multiscale process monitoring method for autocorrelated processes.\n\u003C\/p\u003E\n\u003Cp\u003EContact person: Dave Goldsman (or Jennifer Harris) \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Judy Jin, University of Michigan, Department of Industrial and Operations Engineering, will give a presentation on data fusion for quality improvements in complex systems.","format":"limited_html"}],"field_summary_sentence":[{"value":"Data Fusion for Quality Improvements in Complex Systems"}],"uid":"27279","created_gmt":"2009-10-12 21:20:26","changed_gmt":"2016-10-08 01:47:58","author":"Barbara Christopher","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-03-11T12:00:00-04:00","event_time_end":"2008-03-11T13:00:00-04:00","event_time_end_last":"2008-03-11T13:00:00-04:00","gmt_time_start":"2008-03-11 16:00:00","gmt_time_end":"2008-03-11 17:00:00","gmt_time_end_last":"2008-03-11 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6006","name":"Judy Jin"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJennifer Harris\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:jharris@isye.gatech.edu\u0022\u003EContact Jennifer Harris\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"43852":{"#nid":"43852","#data":{"type":"event","title":"ISyE Faculty Candidate Seminar:  Judy Jin","body":[{"value":"\u003Cp\u003EISyE Faculty Candidate Seminar:  Judy Jin\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"ISyE Faculty Candidate Seminar:  Judy Jin","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Faculty Candidate Seminar:  Judy Jin"}],"uid":"27279","created_gmt":"2009-10-12 21:20:32","changed_gmt":"2016-10-08 01:47:58","author":"Barbara Christopher","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-03-11T12:00:00-04:00","event_time_end":"2008-03-11T13:00:00-04:00","event_time_end_last":"2008-03-11T13:00:00-04:00","gmt_time_start":"2008-03-11 16:00:00","gmt_time_end":"2008-03-11 17:00:00","gmt_time_end_last":"2008-03-11 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6006","name":"Judy Jin"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJennifer  Harris\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:jharris@isye.gatech.edu\u0022\u003EContact Jennifer  Harris\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"43845":{"#nid":"43845","#data":{"type":"event","title":"Lecture: Dynamic Risk-based Scheduling","body":[{"value":"\u003Cp\u003E\u003Cem\u003ETitle:\u003C\/em\u003E Dynamic Risk-based Scheduling\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003ELecturer:\u003C\/em\u003E Mark L.

Indeed, a recent survey indicated that more than two-thirds of the companies surveyed had experienced a supply chain disruption from which they took more than one week to recover. Furthermore, the study revealed that 73 percent of the executives surveyed had a major disruption in the past five years. Of these, 36 percent took more than one month to recover.\n\u003C\/p\u003E\n\u003Cp\u003EWhy does it take companies so long to recover?\u003Cbr \/\u003E\nWhy are so many companies susceptible to disruption?\u003Cbr \/\u003E\nDo the new \u0022Advanced Planning and Optimization\u0022 systems offer any help?\n\u003C\/p\u003E\n\u003Cp\u003EI believe there are at least two reasons why modern supply chains are so susceptible to such disruption: (1) supply chains are not designed with uncertainty in mind and (2) modern planning and scheduling systems and practices are not robust enough to operate under conditions significantly different from those for which they are planned.

Instead of producing a schedule, DRS calculates scheduling parameters that then are used to dynamically determine the schedule. Moreover, DRS provides a method to incorporate recourse strategies in a practical way. For instance, if an alarm indicates there is insufficient capacity, extra capacity can be scheduled before any orders are late. However, deciding how much extra capacity to have and how often it should be used in a difficult optimization problem. The result is a system that is both more robust and more effective than other advanced scheduling techniques. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Mark L.

We identify mathematical conditions under which SOP outperforms the newsvendor type ordering and corroborate them with numerical studies. We also compare SOP to Balanced Ordering Policy (BOP), under which the retailers take turns to order freely in one period of the cycle, and receive fixed shipments in other periods.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Improving the Performance of Distribution Supply Chains By Using Scheduled Synchronized Ordering with Information Sharing","format":"limited_html"}],"field_summary_sentence":[{"value":"Improving the Performance of Distribution Supply Chains"}],"uid":"27279","created_gmt":"2009-10-12 21:20:21","changed_gmt":"2016-10-08 01:47:54","author":"Barbara Christopher","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-03-27T14:30:00-04:00","event_time_end":"2008-03-27T15:30:00-04:00","event_time_end_last":"2008-03-27T15:30:00-04:00","gmt_time_start":"2008-03-27 18:30:00","gmt_time_end":"2008-03-27 19:30:00","gmt_time_end_last":"2008-03-27 19:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"167193","name":"Srinagesh Gavirneni"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EPinar Keskinocak\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:pinar@isye.gatech.edu\u0022\u003EContact Pinar Keskinocak\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"43783":{"#nid":"43783","#data":{"type":"event","title":"Markov Chains \u0026 Optimality of the Hamiltonian Cycle","body":[{"value":"\u003Cp\u003E\u003Cem\u003EPresentation\u003C\/em\u003E: \u003Cstrong\u003EMarkov Chains \u0026amp; Optimality of the Hamiltonian Cycle\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003EAbstract\u003C\/em\u003E: We consider the Hamiltonian cycle problem (HCP) embedded in a controlled Markov decision process. In this setting, HCP reduces to an optimization problem on a set of Markov chains corresponding to a given graph. We prove that Hamiltonian cycles are minimizers for the trace of the fundamental matrix on a set of all stochastic transition matrices. In case of doubly stochastic matrices with symmetric linear perturbation, we show that Hamiltonian cycles minimize a diagonal element of a fundamental matrix for all admissible values of the perturbation parameter. In contrast to the previous work on this topic, our arguments are primarily based on probabilistic rather than algebraic methods.\n\u003C\/p\u003E\n\u003Cp\u003EJoint work with Vladimir Ejov\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003EBio:\u003C\/em\u003E  Nelly Litvak is an Assistant Professor at the University of Twente, The Netherlands, in the Stochastic Operations Research group.

Known mixed integer binary formulations for these constraints have a number of binary variables and extra constraints that is linear in m. We give sufficient conditions for constructing formulations for these constraints with a number of binary variables and extra constraints that is logarithmic in m. Using these conditions we introduce the first mixed integer binary formulations for SOS1 and SOS2 constraints that use a number of binary variables and extra constraints that is logarithmic in the number of continuous variables.We also introduce the first mixed integer binary formulations for piecewise linear functions of one and two variables that use a number of binary variables and extra constraints that is logarithmic in the number of linear pieces of the functions. We prove that the new formulations for piecewise linear functions have favorable tightness properties and present computational results showing that they can significantly outperform other mixed integer binary formulations.

We propose a new model based on Polya processes and the cumulative intensity of counting processes that can calibration the current CDO data very well.

The main objective was to make optimum use of the available workers while maximizing the number of jobs processed during a given time horizon. The workers have a large range of qualifications, the jobs have due dates, and there are several resource modes for most of the productions steps (for instance, short processing times with large number of workers or smaller processing time with fewer workers). Typical manufacturing environments where these conditions can be found are the assembly of planes, turbines, printing machines, or other large one-of-a-kind assembly outputs. Due to the huge number of constraints on scheduling in these environments, it is hard even to find a feasible schedule for theworkers. This was the main reason why we decided to start the development of a simulation-based scheduler. We are more than half way through thisdevelopment process and there are several important \u0022lessons learned\u0022 with respect to the solution approach as such and the data and information requirements we require from our partners in industry. In this talk, I will discuss modeling issues (e.g., is it possible to develop a common model description for a variety of industries?), solution approach issues (e.g., is it possible to find a feasible solution on time?), and data\/information collection issues (e.g., which tools do we need to obtain relevant data\/information from our partners in industry).

GLRT has the very interesting characteristic of performing simultaneous detection and estimation in the case of parameterized pdfs or combined detection and isolation in the case of composite hypotheses. Even though this test is known for years and has been the decision tool in numerous applications, existing results demonstrate only large sample size asymptotic optimality. \n\u003C\/p\u003E\n\u003Cp\u003EIn our presentation we introduce a novel, finite sample size detection\/estimation formulation for the problem of hypothesis testing with unknown parameters and a corresponding detection\/isolation setup for the case of composite hypotheses. The optimum test that results from our performance measure optimization has a GLRT-like structure which is closely related to the criterion we employ for the parameter estimation or isolation part. When this criterion is selected in a very specific manner, we recover the classical GLRT of the literature, while we obtain interesting novel tests with alternative criteria. Our mathematical derivations are surprisingly simple considering that they solve a problem that has been open for more than half a century. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Finite Sample Size Optimality of GLR Tests","format":"limited_html"}],"field_summary_sentence":[{"value":"Finite Sample Size Optimality of GLR Tests"}],"uid":"27187","created_gmt":"2009-10-12 20:38:28","changed_gmt":"2016-10-08 01:47:42","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-08-28T12:00:00-04:00","event_time_end":"2008-08-28T13:00:00-04:00","event_time_end_last":"2008-08-28T13:00:00-04:00","gmt_time_start":"2008-08-28 16:00:00","gmt_time_end":"2008-08-28 17:00:00","gmt_time_end_last":"2008-08-28 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"5781","name":"Finite"},{"id":"5782","name":"GLR"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EAnita  Race\u003C\/strong\u003E\u003Cbr \/\u003EH.

The ill-posed nature of the problem entails the incorporation of regularization techniques. The consequent non-stochastic error introduced by regularization, needs to be taken into account when choosing an experimental design. We discuss different ways to define an optimal design that controls both an average total error of regularized estimates and a measure of the total cost of the design. We also introduce a numerical framework that efficiently implements such designs and natively allows for the solution of large-scale problems. To illustrate the possible applications of the methodology, we consider a borehole tomography example and a two-dimensional function recovery problem. \n\u003C\/p\u003E\n\u003Cp\u003EContact: ISyE DOS Optimization Seminars (\u003Ca href=\u0022http:\/\/www2.isye.gatech.edu\/dos\/\u0022 title=\u0022http:\/\/www2.isye.gatech.edu\/dos\/\u0022\u003Ehttp:\/\/www2.isye.gatech.edu\/dos\/\u003C\/a\u003E)\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Numerical methods for optimal experimental design of ill-posed problems","format":"limited_html"}],"field_summary_sentence":[{"value":"Numerical methods for optimal experimental design of ill-posed problem"}],"uid":"27187","created_gmt":"2009-10-12 20:38:10","changed_gmt":"2016-10-08 01:47:38","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-09-15T16:00:00-04:00","event_time_end":"2008-09-15T17:00:00-04:00","event_time_end_last":"2008-09-15T17:00:00-04:00","gmt_time_start":"2008-09-15 20:00:00","gmt_time_end":"2008-09-15 21:00:00","gmt_time_end_last":"2008-09-15 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"5424","name":"Linear"},{"id":"1377","name":"optimization"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EAnita  Race\u003C\/strong\u003E\u003Cbr \/\u003EH.

The problem becomes more interesting if we put restrictions on the type of embedding. For example, a linkless embedding of a graph is one where each pair of vertex-disjoint circuits has linking number equal to zero. The class of all graphs that have a linkless embedding is closed under taking minors. Robertson, Seymour, and Thomas gave the forbidden minors for this class of graphs.

The suffering, loss of productivity, expenditure of scarce health-care resources, coupled with the rising resistance of many pathogens, make this issue urgent and important. Since it is difficult or expensive to observe colonization and ascertain whether a patient was infected prior to, or during hospitalization, and the process by which pathogens spread depends on the behavior of patients, health-care workers, visitors and the community at large, the best strategy to reduce nosocomial infection rates is unknown. Two possible approaches to reduction include: screening for isolation and improved hygiene approaches.

We assume that each of these components degrades gracefully over time and its degradation process can be modeled using parameterized stochastic degradation models. The presentation discusses a novel approach that identifies the top-k, the k units with the largest residual life (most reliable), using sensor- based prognostic information associated with the critical components of each unit.  We propose a Prognostics-Based Ranking Algorithm (PBR-Algorithm) that combines prognostics-based stochastic degradation models with computer science database ranking algorithms.  The stochastic degradation models are used to compute residual life distributions (RLDs) of partially degraded critical components using condition monitoring data, whereas the ranking algorithm orders the units using the critical component as a ranking predicate and the Median of the RLD as a scoring criterion. The stochastic models used in this work utilize in-situ\u003Cbr \/\u003E\ndegradation signals to continuously update the RLDs, in real-time. This creates a set of dynamically evolving RLDs.  The non-parametric nature of the RLDs coupled with the need to perform real-time computations pose significant challenges in identifying the subset of k units with the largest remaining useful life. In this presentation, we will show that given the time stamp and amplitude\/level of a component\u0027s degradation signal, it is possible to establish stochastic dominance among the RLDs of all the units in the fleet (for a given component type).

Producers submit a price function to the market, which maps a production level to a price. Solutions of this type of models are normally referred to as supply function equilibria, and the most common application is in electricity markets. In our model, producers have increasing marginal production costs equal to a linear function, and adopt price functions that are proportional to their production costs. Therefore, the decision in the first phase of the game is the markup producers apply to the production cost. In a second phase of the game, consumers learn the producers\u0027 price functions, which leads to an allocation of consumers to producers.\n\u003C\/p\u003E\n\u003Cp\u003EWe prove that an equilibrium exists if and only if there are at least three producers, and if an equilibrium exists, it is unique. We also establish that for highly competitive markets, the equilibrium assignment is nearly efficient, where an efficient assignment is one that minimizes the total production cost. Furthermore, we establish an almost tight bound on the worstcase inefficiency of an equilibrium. In particular, the bound states that when there are two equally efficient producers and possibly other less efficient ones, the production cost under an equilibrium is at most 50% worse than the optimal one, and the worst-case gap between the two assignments decreases rapidly as competition increases. For instance, for three similarly-efficient producers plus perhaps other less efficient ones, the inefficiency is below 6.2%.\n\u003C\/p\u003E\n\u003Cp\u003EThis is joint work with Nicolas Stier-Moses. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Pricing with markups in congested markets","format":"limited_html"}],"field_summary_sentence":[{"value":"Pricing with markups in congested markets"}],"uid":"27187","created_gmt":"2009-10-12 20:37:48","changed_gmt":"2016-10-08 01:47:34","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-10-16T12:00:00-04:00","event_time_end":"2008-10-16T13:00:00-04:00","event_time_end_last":"2008-10-16T13:00:00-04:00","gmt_time_start":"2008-10-16 16:00:00","gmt_time_end":"2008-10-16 17:00:00","gmt_time_end_last":"2008-10-16 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"5674","name":"Equilibrium"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EAnita  Race\u003C\/strong\u003E\u003Cbr \/\u003EH.

Already the largest component of labor cost in the warehouse, order picking systems are being stressed because customers are ordering more frequently and the orders are becoming smaller. For this reason efficiency in order picking is becoming more critical. Quality, efficiency, the right throughput time for order picking are strongly  influenced by the selection of the order picking system. In this talk, examples for selection criteria will be given and application examples will be presented that show how order picking systems have been designed by the combination of well known material handling components.  The talk also will address the interactions between order picking requirements, order picking concepts the current direction of order picking automatization.\n\u003C\/p\u003E\n\u003Cp\u003EAbout the speaker:  Detlef Spee received the Dipl.-Ing. from the University of Dortmund in 1985, where he then worked as a scientist in conveyor technology for a year.

The objective is to choose a staffing level that minimizes the sum of personnel costs and abandonment\/waiting time costs. We formulate a simple fluid analogue, which is in essence a newsvendor problem, and demonstrate that the solution it prescribes performs remarkably well. In particular, the gap between the performance of the optimal staffing level and that of our proposed prescription is independent of the \u0022size\u0022 of the system, i.e., it  remains bounded as the system size (demand volume) increases. This stands in contrast to the more conventional theory that applies when arrival rates are known, and commonly used rules-of-thumb predicated on it. Specifically,  in that setting the difference between the optimal performance and that of the fluid solution diverges at a rate proportional to square-root of the size of the system. One manifestation of this is the celebrated square root safety staffing principle that dates back to work of Erlang, which augments solutions of the deterministic analysis with additional servers of order square root the volume of demand. In our work, we establish that this type of prescription is needed only when arrival rates are suitably \u0022predictable.\u0022\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Capacity Planning in Service Systems with Arrival Rate Uncertainty: Safety Staffing Principles Revisited","format":"limited_html"}],"field_summary_sentence":[{"value":"Capacity Planning Service Systems Arrival Rate Uncertainty"}],"uid":"27187","created_gmt":"2009-10-12 20:37:34","changed_gmt":"2016-10-08 01:47:30","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-11-20T11:00:00-05:00","event_time_end":"2008-11-20T12:30:00-05:00","event_time_end_last":"2008-11-20T12:30:00-05:00","gmt_time_start":"2008-11-20 16:00:00","gmt_time_end":"2008-11-20 17:30:00","gmt_time_end_last":"2008-11-20 17:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"5600","name":"Capacity"},{"id":"167163","name":"service systems"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EHayriye Ayhan\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:hayhan@isye.gatech.edu\u0022\u003EContact Hayriye Ayhan\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"43236":{"#nid":"43236","#data":{"type":"event","title":"Integrated production-distribution model with inventory considerations","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ETITLE:\u003C\/strong\u003E  An integrated production-distribution model with inventory considerations\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ESPEAKER:\u003C\/strong\u003E Aly Megahed\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EABSTRACT:\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003EMuch research has been conducted in the area of supply chain network design.

MIQCP problems are very difficult because they combine two kinds of non-convexities: integer variables and non-convex quadratic constraints. To produce strong relaxations of MIQCP problems, we use techniques from disjunctive programming and the lift-and-project methodology. In particular, we propose new methods for generating valid inequalities by using the equation Y = xx^T. We use the concave constraint 0 succcurlyeq Y - xx^T to derive disjunctions of two types. The first ones are directly derived from the eigenvectors of the matrix Y - xx^T with positive eigenvalues, the second type of disjunctions are obtained by combining several eigenvectors in order to minimize the \u0022width\u0022 of the disjunction. We also use the convex SDP constraint Y - xx^T succcurlyeq 0 to derive convex quadratic cuts, and we combine both approaches in a cutting plane algorithm. We present computational results to illustrate our findings.\n\u003C\/p\u003E\n\u003Cp\u003EConvex Relaxations of Non-Convex Mixed Integer Quadratically Constrained Programs\u003Cbr \/\u003E\n\u003Ca href=\u0022http:\/\/www.optimization-online.org\/DB_HTML\/2008\/11\/2145.html\u0022 title=\u0022http:\/\/www.optimization-online.org\/DB_HTML\/2008\/11\/2145.html\u0022\u003Ehttp:\/\/www.optimization-online.org\/DB_HTML\/2008\/11\/2145.html\u003C\/a\u003E\n\u003C\/p\u003E\n\u003Cp\u003EA common way to produce a convex relaxation of a Mixed Integer Quadratically Constrained Program (MIQCP) is to lift the problem into a higher dimensional space by introducing variables Y_{ij} to represent each of the products x_i x_j of variables appearing in a quadratic form. One advantage of such extended relaxations is that they can be efficiently strengthened by using the (convex) SDP constraint Y - x x^T succeq 0 and disjunctive programming. On the other hand, their main drawback is their huge size, even for problems of moderate size. In this paper, we study methods to build low-dimensional relaxations of MIQCP that capture the strength of the extended formulations. To do so, we use projection techniques pioneered in the context of the lift-and-project methodology. We show how the extended formulation can be algorithmically projected to the original space by solving linear programs. Furthermore, we extend the technique to project the SDP relaxation by solving SDPs. In the case of an MIQCP with a single quadratic constraint, we propose a subgradient-based heuristic to efficiently solve these SDPs. We also propose a new \u0022eigen reformulation\u0022 for MIQCP, and a cut generation technique to strengthen this reformulation using polarity. We present extensive computational results to illustrate the efficiency of the proposed techniques. Our computational results have two highlights. First, on the GLOBALLib instances, we are able to generate relaxations that are almost as strong as those proposed in our companion paper even though our computing times are about 100 times smaller, on average. Second, on the box QP instances, the strengthened relaxations generated by our code are almost as strong as the well-studied SDP+RLT relaxations and can be solved in less than 2 sec even for larger instances with 100 variables; the SDP+RLT relaxations of the same set of instances can take up to a couple of hours to solve using a state-of-the-art SDP solver.\n\u003C\/p\u003E\n\u003Cp\u003EThis is joint work with Pierre Bonami and Jon Lee\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Convex Relaxations of Non-Convex Mixed Integer Quadratically Constrained Programs","format":"limited_html"}],"field_summary_sentence":[{"value":"Convex Relaxations of Non-Convex Mixed Integer Programs"}],"uid":"27187","created_gmt":"2009-10-12 20:37:29","changed_gmt":"2016-10-08 01:47:30","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-11-25T14:00:00-05:00","event_time_end":"2008-11-25T14:00:00-05:00","event_time_end_last":"2008-11-25T14:00:00-05:00","gmt_time_start":"2008-11-25 19:00:00","gmt_time_end":"2008-11-25 19:00:00","gmt_time_end_last":"2008-11-25 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"5575","name":"MIQCP"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EAnita  Race\u003C\/strong\u003E\u003Cbr \/\u003EH.

Technological advances have made it feasible to perform case-control association studies on a genome-wide basis. Some of the characteristics of the data include missing information, and the need to analyze hundreds of thousands or millions of genetic markers in a single study, which puts a premium on computational speed of the methods. The observations in these studies can have several sources of dependence, including population structure and relatedness among the sampled individuals, where some of this structure may be unknown. Neglecting such structure in the data can lead to seriously spurious associations.

Motivated by the demand for Open-Source solvers for real-world MINLP problems, we have developed a spatial Branch-and-Bound software package named couenne (Convex Over- and Under-ENvelopes for Nonlinear Estimation). In this talk, we present the structure of couenne and discuss in detail our work on two of its components: bounds tightening and branching strategies. We then present experimental results on a set of MINLP instances including some industrial applications. We also compare the performance of couenne with a state-of-the-art solver for nonconvex MINLPs.\n\u003C\/p\u003E\n\u003Cp\u003EJoint work with P. Belotti (Lehigh); L. Biegler, G. Cornuejols, I.
