For a centralized system we summarize recent advances related to\noperational and design aspects of the problem. Our main focus in this talk is\non the decentralized system, in which the retailers operate to maximize their\nown profit. This causes incentive problems that prevent coordination, even with\ntwo retailers who may pay each other for transshipped units. We propose a new\nmechanism based on a transshipment fund which is the first to coordinate the\nsystem, in a fully non-cooperative setting, for all instances of two retailers\nas well as all instances of any number of retailers. The computation and\ninformation requirements of this mechanism are realistic and relatively modest.\nWe also present necessary and sufficient conditions for coordination and prove\nthey are always satisfied with our mechanism.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u0026nbsp;\u0026nbsp; \u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMichal Tzur\u003C\/strong\u003E is an Associate Professor in the Industrial Engineering\ndepartment at the Faculty of Engineering at Tel Aviv University in Israel,\nwhere she served as the head of the\nundergraduate program and as the department chair.
