A key issue to be resolved when carriers work together in such a manner is how to distribute profit among participating members. We seek to establish a mechanism for allocating profits among cargo carriers who choose to collaborate by sharing capacity on all or a portion of their network. The mechanism should achieve a collaborative system in which (1) system profit is maximized, (2) in the absence of a centralized decision-maker, individual carriers are motivated to make decisions that achieve maximum system profit, and (3) allocations dictated by the mechanism are implementable. Critical components in the design of a mechanism to allocate system profits are the underlying mathematical models. How do we mathematically represent the interests of the system and of individual carriers within the system? We analyze two different modeling approaches and show how differences in modeling lead to significant differences in the properties of the resulting allocations. We find that one model is more flexible in terms of the range of allocations obtained under the model, and we explore how this flexibility may be used to strive for different measures of fairness. We also discuss complications that arise from this flexibility, namely the existence of a secondary market for capacity, which benefits some carriers in the collaboration, at the expense of others.

The conventional Shewhart R and S charts address the setting where the in-control process readings have a constant variance. In some settings, however, it is the coefficient of variation, rather than the variance, that should be constant. For example this setting is common in clinical chemistry, and then conventional R and S charts cannot be used. This paper develops a chart, equivalent to the S chart, for monitoring the coefficient of variation using rational groups of observations. (This is joint work with Man S. Lee and Young J.

If such a strain emerges, and is not controlled at source, a pandemic is likely to result. Health policy in most countries will then be focused on reducing morbidity and mortality. We estimate the expected reduction in primary attack rates for different household-based interventions using a mathematical model of influenza transmission within and between households. We show that, for lower transmissibility strains, the combination of household-based quarantine, isolation of cases outside the household, and targeted prophylactic use of anti-virals will be highly effective and likely feasible across a range of plausible transmission scenarios. For example, for a basic reproductive number (the average number of people infected by a typically infectious individual in an otherwise susceptible population) of 1.8, assuming only 50% compliance, this combination could reduce the infection (symptomatic) attack rate from 74% (49%) to 40% (27%), requiring peak quarantine and isolation levels of 6.2%and 0.8% of the population, respectively, and an overall anti-viral stockpile of 3.9 doses per member of the population. Although contact tracing may be additionally effective, the resources required make it impractical in most scenarios. National influenza pandemic preparedness plans currently focus on reducing the impact associated with a constant attack rate, rather than on reducing transmission. Our findings suggest that the additional benefits and resource requirements of household-based interventions in reducing average levels of transmission should also be considered, even when expected levels of compliance are only moderate.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"ISyE Seminar: Reducing the Impact of the Next Influenza Pandemic Using Household-Based Public Health Interventions","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Seminar:  Joseph T.

By formulating such problems as stochastic optimization problems and resorting to stochastic optimization and variational convergence techniques, one can obtain constructive procedures in situations that go much beyond the classical Black-Scholes framework. In the process, one derives some important properties such as no-arbitrage and nearly no-arbitrage conditions, equivalent martingale measures, equilibrium equation, etc. Implementation of this strategy requires an, as good as possible, estimate of the price process. A novel estimation approach, that relies on Levy\u0027s characterization of a Wiener process, is suggested and implemented experimentally.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Pricing Contingent Claims \u0026amp; Evaluating Market Risk","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Guest Lecturer:  Professor Roger J-B Wets"}],"uid":"27216","created_gmt":"2009-10-12 21:22:56","changed_gmt":"2016-10-08 01:48:27","author":"Ruth Gregory","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-01-25T13:00:00-05:00","event_time_end":"2007-01-25T14:00:00-05:00","event_time_end_last":"2007-01-25T14:00:00-05:00","gmt_time_start":"2007-01-25 18:00:00","gmt_time_end":"2007-01-25 19:00:00","gmt_time_end_last":"2007-01-25 19:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6393","name":"ISyE Guest Lecturer"},{"id":"6413","name":"Roger J-B Wets"}],"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\u003EAlex Shapiro\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:alex.shapiro@isye.gatech.edu\u0022\u003EContact Alex Shapiro\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"44580":{"#nid":"44580","#data":{"type":"event","title":"ISyE Statistics Seminar: Dr. Philippe Rigollet","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EISyE Statistics Seminar: Stochastic convex optimization using mirror averaging algorithms\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EGUEST LECTURER\u003C\/strong\u003E\u003Cbr \/\u003E\nDr. Philippe Rigollet\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EAFFILIATION\u003C\/strong\u003E\u003Cbr \/\u003E\nSchool of Mathematics, Georgia Tech\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EABSTRACT\u003C\/strong\u003E\u003Cbr \/\u003E\nSeveral statistical problems where the goal is to minimize an unknown convex risk function, can be formulated in the general framework of stochastic convex optimization.

It is estimated that US industry spends $200 billion each year on reliability and maintenance.

Many physical degradation processes that occur prior to failure can only be observed indirectly using condition\/health monitoring techniques that capture degradation-based sensory information. This research rests on the idea that the functional forms of degradation-based sensory signals are driven by the underlying physical degradation phenomena that occur prior to failure. The approach used in this research is to model the evolution of degradation signals using continuous-time continuous-state stochastic models. These stochastic models combine two sources of information; (1) population-specific reliability and degradation characteristics, which are used to estimate preliminary residual life distributions; and (2) in-situ component-specific degradation signals, which are used to update the residual life distributions, in real-time, based on the latest degradation states of the systems being monitored. These dynamically evolving degradation-based residual life distributions will then be utilized to improve reliability assessment and enable the development of sensor-driven replacement and spare parts inventory decision models.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"A Prognostic Degradation-Based Methodology for Improving Reliability Assessment and Maintenance Management.","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Guest Lecturer:  Dr. Nagi Gebraeel"}],"uid":"27216","created_gmt":"2009-10-12 21:22:56","changed_gmt":"2016-10-08 01:48:27","author":"Ruth Gregory","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-02-07T10:00:00-05:00","event_time_end":"2007-02-07T11:00:00-05:00","event_time_end_last":"2007-02-07T11:00:00-05:00","gmt_time_start":"2007-02-07 15:00:00","gmt_time_end":"2007-02-07 16:00:00","gmt_time_end_last":"2007-02-07 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6411","name":"Dr. Nagi Gebraeel"},{"id":"6393","name":"ISyE Guest Lecturer"}],"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\u003EJC Lu\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:jclu@isye.gatech.edu\u0022\u003EContact JC Lu\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"44578":{"#nid":"44578","#data":{"type":"event","title":"ISyE Guest Lecturer:  Yuri Nesterov","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ESecond-order Methods with Provable Global Complexity\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EGUEST LECTURER\u003C\/strong\u003E\u003Cbr \/\u003E\nYuri Nesterov\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EAFFILIATION\u003C\/strong\u003E\u003Cbr \/\u003E\nCORE, Belgium\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EABSTRACT\u003C\/strong\u003E\u003Cbr \/\u003E\nIn this talk we discuss a recent progress in the general second-order minimization schemes related to the cubic regularization of the Newton\u0027s method.

An example of considerable recent interest arises when considering computer models of processes; the output of such models is a function over the space of inputs of the computer model. The output is functional data in many contexts, such as when the output is a function of time, a surface, etc. A nonparametric Bayesian statistics approach, utilizing separable Gaussian Stochastic Process as the prior distribution for functions, is a natural choice for smooth functions in a manageable (time) dimension. However, direct use of separable Gaussian stochastic processes is inadequate for irregular functions, and can be computationally infeasible in high dimensional cases.

As an example, dimensional variation of automobile bodies may lead to assembly, aestethic, warranty and safety problems. Therefore, variation should be minimized whenever possible. In this talk I will introduce my research on active compensation of deviation and the design of MMPs focused on variation reduction. Through my talk I will demostrate how those research areas can be integrated. The first part of the presentation will focused on the development of a methodology for active compensation of deviations in MMPs. In particular, I will present the derivation of a feedforward control algorithm for variation reduction, which incorporates process and product constraints. In the second part of my talk, I will show how the above mentioned methodology can be used in the determination of the optimal distribution of actuators, which are used to perform compensations. The third part of the presenetation will focused on robust design of multistage assembly processes.

In traditional manufacturing, it has been observed that different error sources may result in identical error patterns on product features. This so-called error equivalence phenomenon could have dual effects on dimensional control: significantly increasing the complexity of root cause identification, and providing an opportunity to use one error source to counteract or compensate the others. In a complex system like human physiology, interaction is a fundamental mechanism of processing and coding information. Understanding complex interactions through observed physiologic signals is vital to diagnosis and treatment of a wide range of medical problems. In nanomanufacturing, relating macro\/micro scale functional process variables with nanoscale nanostructure defects is a key step to implement process control for improving process yield and repeatability.\n\u003C\/p\u003E\n\u003Cp\u003EA common methodological framework of modeling and analyzing complex process\/system phenomena is to integrate subject matter knowledge with mathematical modeling tools. The challenge lies in the interdisciplinary nature of the problems of interest. In this talk, the speaker will first introduce error equivalence modeling through kinematic analysis. The impact of error equivalence concept on dimensional variation control will be demonstrated through a new sequential root cause identification procedure and a novel error-compensating-error strategy. To understand physiologic interactions, a novel nonlinear dynamics model was developed to consider not only complex spatial patterns among multiple nonstationary signals, but also temporal patterns within individual signals. Validated by controlled physiologic experiments, the proposed model formulation provides better insight into interaction mechanisms, such as the interaction order, strength, and structure. In nanomanufacturing application, the speaker will discuss the research challenges and ideas for quality control of nanostructure growth processes.

Analysis of a large data set shows that forecast errors can be large relative to the fluctuations naturally expected in a Poisson process. We show that ignoring forecast errors typically leads to over-estimates of performance, and that forecast errors of the magnitude seen in our data set can have a practically significant impact on predictions of long-run performance. We also define short-run performance as the random percentage of calls received in a particular period that are answered in a timely fashion. We prove a central limit theorem that yields a normal-mixture approximation for its distribution for Markovian queues, and sketch an argument that shows that a normal-mixture approximation should be valid in great generality.

The motivation comes from applications to Diffusion Tensor Imaging, a brain imaging technique used, in particular, to recover the paths of neural fibers in the brain based on diffusion data. An estimator will be discussed for which it is possible to establish asymptotic normality (in the sense of convergence in distribution in a functional space). This provides formulas for asymptotic distributions of several statistics of interest, such as the distance from the estimated curve to a given region.

The model has a single item, a single location, two demand classes, and operates under discrete review. There is a fixed positive replenishment lead time and unlimited backlogging of unmet demand is allowed. There are no order setup costs, and both holding costs and backlogging costs are linear. If the backlogging costs are the same for both classes then this reduces to the classical model of Karlin and Scarf (1958), who showed that a \u0027base-stock\u0027 policy is optimal. We are interested in the case where the backlogging costs are different for the two classes. Although it is intuitively clear that the demand class with the larger backlog cost should be treated better, the optimal policy for operating this system is not known. The simplest way to give priority to one class is to satisfy all backlogs from that class before backlogs of the other class are satisfied. A stronger preference can be given by holding some items in reserve for the higher priority class. We present an asymptotic analysis, in the long lead time limit, of these priority policies. This analysis shows that the simple priority policy (without reservation) is asymptotically optimal. The priority policy with reservation is also asymptotically optimal if the reservation threshold does not grow too fast with the lead time.\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EDATE \u0026amp; TIME\u003C\/strong\u003E\u003Cbr \/\u003E\nTuesday, May 15, 2007 -- 11:00 AM\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EDURATION\u003C\/strong\u003E\u003Cbr \/\u003E\n1 hour\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ELOCATION\u003C\/strong\u003E\u003Cbr \/\u003E\nExecutive Classroom 228, Main\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ECONTACT PERSON\u003C\/strong\u003E\u003Cbr \/\u003E\nJim Dai\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"An Inventory Model with Two Demand Classes","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Guest Lecturer:  Marty Reiman"}],"uid":"27216","created_gmt":"2009-10-12 21:22:53","changed_gmt":"2016-10-08 01:48:27","author":"Ruth Gregory","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-05-15T12:00:00-04:00","event_time_end":"2007-05-15T13:00:00-04:00","event_time_end_last":"2007-05-15T13:00:00-04:00","gmt_time_start":"2007-05-15 16:00:00","gmt_time_end":"2007-05-15 17:00:00","gmt_time_end_last":"2007-05-15 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6389","name":"An Inventory Model with Two Demand Classes"},{"id":"6388","name":"ISyE Guest Lecturer:  Marty Reiman"}],"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\u003EJim Dai\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:jim.dai@isye.gatech.edu\u0022\u003EContact Jim Dai\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"44562":{"#nid":"44562","#data":{"type":"event","title":"ISyE Guest Lecturer:  Dr. Gideon Weiss","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003EA push pull multi-class queueing system with infinite supply of work\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EGUEST LECTURER\u003C\/strong\u003E\u003Cbr \/\u003E\nDr. Gideon Weiss\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EAFFILIATION\u003C\/strong\u003E\u003Cbr \/\u003E\nUniversity of Haifa\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EABSTRACT\u003C\/strong\u003E\u003Cbr \/\u003E\nMulti-class queueing networks with infinite supply of work provide a new paradigm for queueing systems under balanced heavy traffic. In particular, they allow full utilization of the servers without congestion, and the balanced heavy traffic arises naturally, and is not the result of exogenous arrivals.\n\u003C\/p\u003E\n\u003Cp\u003EIn this talk we focus on the following illustrative example: We consider a multi-class queueing system with two service stations and four classes, where there are two streams of customers, one stream is processed first in station 1 and then in station 2, the other stream moves in the opposite direction. This push pull system is distinguished from the network of Rybko and Stolyar in that be assume that there is an unlimited number of customers available in each of the two streams. Hence, both service stations can be busy all the time, i.e. work at utilization rho=1. We assume processing times are memory-less. We find a family of generalized threshold policies for which this system is stable, i.e. positive recurrent, with this full utilization. We derive the steady state distribution for some of these policies.\n\u003C\/p\u003E\n\u003Cp\u003EJoint work with Anastasia Kopzon \n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EDATE \u0026amp; TIME\u003C\/strong\u003E\u003Cbr \/\u003E\nWednesday, May 16, 2007 -- 11:00 AM\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EDURATION\u003C\/strong\u003E\u003Cbr \/\u003E\n1 hour\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ELOCATION\u003C\/strong\u003E\u003Cbr \/\u003E\nRoom 228 Executive Classroom, Main bldg\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003ECONTACT PERSON\u003C\/strong\u003E\u003Cbr \/\u003E\nAlex Shapiro\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"A push pull multi-class queueing system with infinite supply of work","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Guest Lecturer:  Dr. Gideon Weiss"}],"uid":"27216","created_gmt":"2009-10-12 21:22:53","changed_gmt":"2016-10-08 01:48:27","author":"Ruth Gregory","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-05-16T12:00:00-04:00","event_time_end":"2007-05-16T13:00:00-04:00","event_time_end_last":"2007-05-16T13:00:00-04:00","gmt_time_start":"2007-05-16 16:00:00","gmt_time_end":"2007-05-16 17:00:00","gmt_time_end_last":"2007-05-16 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6387","name":"A push pull multi-class queueing system with infinite supply of work"},{"id":"6386","name":"ISyE Guest Lecturer:  Dr. Gideon Weiss"}],"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\u003EAlex  Shapiro\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:alex.shapiro@isye.gatech.edu\u0022\u003EContact Alex  Shapiro\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"44561":{"#nid":"44561","#data":{"type":"event","title":"Senior Faculty Candidate Seminar:  Dr. Jianjun Shi","body":[{"value":"\u003Cp\u003E\u003Cstrong\u003ESenior Faculty Candidate Seminar\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EGUEST LECTURER\u003C\/strong\u003E\u003Cbr \/\u003E\nDr. Jianjun Shi\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EAFFILIATION\u003C\/strong\u003E\u003Cbr \/\u003E\nUniversity of Michigan\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EDATE \u0026amp;

However, a system-wide focus, e.g., a collaborative focus, opens up cost saving opportunities that are impossible to achieve with an internal company focus. With the availability of timely and accurate information, new collaborative opportunities which create mutual benefit by taking advantage of operational synergies between buyers, sellers, or buyers and sellers are now arising. Collaborative logistics is viewed by many logistics professionals as a promising opportunity for reducing logistics costs and therefore increasing profitability and economic prosperity.  Hence there is a need to develop a fundamental knowledge base for designing, analyzing, implementing, and managing such collaborative logistics initiatives.\n\u003C\/p\u003E\n\u003Cp\u003EThe workshop will focus on efforts in that direction and will have a variety of talks on topics related to models and methods of collaboration, including supply chain coordination, auctions, computation and games, learning and games, and logistics collaboration in practice.

The noise factors are classified into a few distinct categories based on their impact on the measurement system. A random coefficients model that accounts for the effect of control factors and each category of noise factors on the signal-response relationship is proposed. A suitable performance measure is developed using this general model, and conditions under which it reduces to the usual dynamic signal-to-noise (SN) ratio are discussed. Two different data analysis strategies -- response function modeling (RFM) and performance measure modeling (PMM) -- for modeling and optimization are proposed and compared.\n\u003C\/p\u003E\n\u003Cp\u003ETirthankar Dasgupta was a PhD student in ISyE working with Professor Jeff Wu.

Applications of the CARP arise in garbage collection, snow removal, street sweeping and gritting, mail delivery, meter reading, school bus routing, etc.\n\u003C\/p\u003E\n\u003Cp\u003EWhile the CARP is a central problem in arc routing and has been known for a long time, it is still almost exclusively tackled by means of heuristics. The only available exact method for the CARP is a parallel branch-and-bound algorithm proposed by Hirabayashi et al. (1992), and Kiuchi et al. (1995), in which a lower bound is computed at each node through a node duplication lower bounding procedure (Hirabayashi et al., 1992). Transformations of the CARP into an equivalent node routing problem (namely the Capacitated Vehicle Routing Problem, CVRP) have been proposed by Pearn (1987), Longo et al. (2006), and Baldacci and Maniezzo (2006). Lower bounds have been obtained by Belenguer and Benavent (1992, 1998, 2003) through cutting plane procedures, and Wels (1994) has proposed valid inequalities and separation procedures for the directed version of the CARP.\n\u003C\/p\u003E\n\u003Cp\u003ERecently, Ghiani et al. (2007) proposed a pure binary linear integer program for the undirected CARP, on the basis of an extension of a previous formulation by Belenguer and Benavent (1998), and they developed a fully automated branch-and-cut algorithm. Computational results indicate that the algorithm is able to solve, for the first time ever, all the benchmark instances proposed by DeArmon (1981), and Benavent et al.

When the usual state of affairs is no longer, we want to be aware of the change. (Is there global warming? Has the incidence rate of breast cancer increased? Is there a change in the volatility of the stock market?) Unfortunately, often there is no one around to tell us that things are not what they used to be, and we have to rely on a sequence of (invariably noisy) observations to discern that things are different. Intuitively, if the behavior of \u0022recent\u0022 observations seems \u0022abnormal\u0022, we would be prone to declare that a change is in effect. As usual, the problem is in the details: what do \u0022recent\u0022 and \u0022abnormal\u0022 mean in practice? Moreover, if we are trigger-happy, there will be many false alarms; if we are too hesitant, the delay between a real change and its detection may be very costly. Subject to a constraint on the rate of false alarms, what is the best average delay (between a true change and its detection) attainable? What is a good procedure?\n\u003C\/p\u003E\n\u003Cp\u003EThis talk will present a short review of the change point problem and some of its solutions. The early proposed methods turned out to be optimal in the ideal case that both pre-change and post-change distributions (of an independent sequence of observations, iid pre-change and iid post-change) are known. More recent research relaxed these assumptions. The talk will concentrate on a set of scenarios where progressively less is known about the distributions of the observations, culminating in nonparametric procedures for cases where nothing (other than independence) is assumed about the pre- and post- change distributions.\n\u003C\/p\u003E\n\u003Cp\u003EPlease contact Yajun Mei (\u003Ca href=\u0022mailto:yajun.mei@isye.gatech.edu\u0022\u003Eyajun.mei@isye.gatech.edu\u003C\/a\u003E) if you want to talk to the speaker.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"This talk will present a short review of the change point problem and some of its solutions.","format":"limited_html"}],"field_summary_sentence":[{"value":"Speaker: Moshe Pollak"}],"uid":"27216","created_gmt":"2009-10-12 21:21:56","changed_gmt":"2016-10-08 01:48:15","author":"Ruth Gregory","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-10-16T12:00:00-04:00","event_time_end":"2007-10-16T13:00:00-04:00","event_time_end_last":"2007-10-16T13:00:00-04:00","gmt_time_start":"2007-10-16 16:00:00","gmt_time_end":"2007-10-16 17:00:00","gmt_time_end_last":"2007-10-16 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"426","name":"isye"},{"id":"6268","name":"Moshe Pollak"},{"id":"167227","name":"Speaker series"}],"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\u003EYajun Mei\u003C\/strong\u003E\u003Cbr \/\u003EISyE\u003Cbr \/\u003E\u003Ca href=\u0022mailto:yajun.mei@isye.gatech.edu\u0022\u003EContact Yajun Mei\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"44255":{"#nid":"44255","#data":{"type":"event","title":"ISyE Statistics Seminar:  Lijian Yang","body":[{"value":"\u003Cp\u003ESpeaker: Lijian Yang, Department of Statistics and Probability at Michigan State University\u003Cbr \/\u003E\nPlace: ISyE Main, Executive Classroom, Rm# 228\u003Cbr \/\u003E\nTime: Thursday October 18, 11:00 am\n\u003C\/p\u003E\n\u003Cp\u003ETitle: \u003Cem\u003EPolynomial Spline Confidence Bands for Regression Curves\u003C\/em\u003E\n\u003C\/p\u003E\n\u003Cp\u003EAbstract: Asymptotically exact and conservative confidence bands are obtained for a nonparametric re\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"ISyE Statistics Semnar featuring Dr. Lijian Yang, Department of Statistics and Probability at Michigan State University.","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Statistics Seminar:  Lijian Yang"}],"uid":"27216","created_gmt":"2009-10-12 21:21:55","changed_gmt":"2016-10-08 01:48:15","author":"Ruth Gregory","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-10-18T12:00:00-04:00","event_time_end":"2007-10-18T13:00:00-04:00","event_time_end_last":"2007-10-18T13:00:00-04:00","gmt_time_start":"2007-10-18 16:00:00","gmt_time_end":"2007-10-18 17:00:00","gmt_time_end_last":"2007-10-18 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www2.isye.gatech.edu\/statistics\/index.php","title":"ISyE Statistics Group"}],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"426","name":"isye"},{"id":"6260","name":"Lijian Yang"},{"id":"167194","name":"seminar series"},{"id":"167169","name":"statistics"},{"id":"3503","name":"xiaoming huo"}],"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@isye.gatech.edu\u0022\u003EContact Xiaoming Huo\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"44244":{"#nid":"44244","#data":{"type":"event","title":"ISyE Statistics Seminar:  Harriet Black Nembhard","body":[{"value":"\u003Cp\u003ESpeaker: Harriet Black Nembhard, Ph.D., The Pennsylvania State University\u003Cbr \/\u003E\nTime: Tuesday October 23, 2007;

The approaches used in syndromic surveillance are similar to those in traditional statistical monitoring. We develop the multivariate cuscore (MCS) control chart and the high density (HD) control chart to aid in early detection. Existing relevant approaches in the literature include nonparametric analogues and the multivariate changepoint (MCP). We demonstrate how these statistical methods can be applied on influenza-like illnesses (ILI) data from the US and France. Challenges are presented by the fact that ILI data are non-normal, not independent, and often nonstationary. In addition, we explore how these statistical methods can be refined to take advantage of prior information about health system characteristics such as increases in over-the-counter medication sales and seasonal patterns of outbreaks.\n\u003C\/p\u003E\n\u003Cp\u003EBiosketch:  Harriet Black Nembhard is an associate professor of industrial and manufacturing engineering at the Pennsylvania State University and director of the Laboratory for Quality Engineering and System Transitions (QUEST).

In financial economics, there is extensive research on modeling and forecasting volatility up to the daily level based on Black-Scholes, diffusion, GARCH, stochastic volatility models and implied volatilities from option prices. Nowadays, thanks to technological innovations, high-frequency financial data are available for a host of different financial instruments on markets of all locations and at scales like individual bids to buy and sell, and the full distribution of such bids.\n\u003C\/p\u003E\n\u003Cp\u003EThe availability of high-frequency data stimulates an upsurge interest in statistical research on better estimation of volatility. This talk will start with a review on low-frequency financial time series and high-frequency financial data. Then I will introduce popular realized volatility computed from high-frequency financial data and present my work on wavelet methods for analyzing jump and volatility variations and the matrix factor model for handling large size volatility matrices. The proposed wavelet based methodology can cope with both jumps in the price and market microstructure noise in the data, and estimate both volatility and jump variations from the noisy data.

These so-called accelerated recurrence time models postulate that time to expected recurrence frequency, upon transformation, is a linear function of covariates with frequency-dependent coefficients. This modeling strategy shares the same spirit as quantile regression. An estimation and inference procedure is developed by generalizing the celebrated Powell\u0027s (1984, 1986) estimator for censored quantile regression. Consistency and asymptotic normality of the proposed estimator are established. An algorithm is devised to attain good computational efficiency. Simulations demonstrate that this proposal performs well under practical settings. This methodology is illustrated in an application to the well-known bladder cancer study.\n\u003C\/p\u003E\n\u003Cp\u003EThis talk is based on joint work with Limin Peng. \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Dr. Yijian Huang\nAssociate Professor\nDepartment of Biostatistics\nRollins School of Public Health\nEmory University","format":"limited_html"}],"field_summary_sentence":[{"value":"ISyE Statistics Series"}],"uid":"27216","created_gmt":"2009-10-12 21:21:41","changed_gmt":"2016-10-08 01:48:11","author":"Ruth Gregory","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2007-11-15T10:00:00-05:00","event_time_end":"2007-11-15T11:00:00-05:00","event_time_end_last":"2007-11-15T11:00:00-05:00","gmt_time_start":"2007-11-15 15:00:00","gmt_time_end":"2007-11-15 16:00:00","gmt_time_end_last":"2007-11-15 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www2.isye.gatech.edu\/statistics\/seminar_series.php","title":"ISyE Statistics Group"}],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[{"id":"6227","name":"ISyE Stewart School"},{"id":"167190","name":"Statistics 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\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\u003E404-894-2300\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}},"44141":{"#nid":"44141","#data":{"type":"event","title":"Atlanta INFORMS Meeting","body":[{"value":"\u003Cp\u003EJohn Harris of Southern Company will discuss the company\u0027s use of Operations Research methods to improve utilization of the rail cars that haul coal to their various plants in the southeastern United States.\n\u003C\/p\u003E\n\u003Cp\u003EWe will meet for a reception (with refreshments) at 5:30 PM Thursday November 29, 2007 in the Executive Classroom at the ISyE School at Georgia Tech.

This situation is typical of most remanufacturing environments, where inputs are product returns (also called cores). Production (remanufacturing) cost increases as the quality level decreases, and any unused cores may be salvaged at a value that increases with their quality level. Decision variables include, for each period and under a certain probabilistic scenario, the amount of cores to grade, the amount to remanufacture for each quality level and the amount of inventory to carry over for future periods for un-graded cores, graded cores, and finished remanufactured products. Our model is grounded with data collected at a major OEM that also remanufactures.  We formulate the problem as a stochastic program, and illustrate how the deterministic version of the problem yields solutions that cannot be implemented in practice. The stochastic program, although a large linear program, can be solved easily using Cplex.  We provide a numeric study to generate insights into the nature of the solution.\n\u003C\/p\u003E\n\u003Cp\u003EPizza and refreshments sponsored by The Supply Chain Logistics Institute (SCL).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"The Supply Chain and Logistics Seminar Series featuring Gil Souza, University of Maryland.
