报告名称:Inventory Centralization Games 报告人:Prof. Xin Chen (University of Illinois at Urbana-Champaign, U.S.A) 报告摘要: As companies start exploring innovative collaboration strategies in effort to improve their supply chain efficiency, getting all players to agree on how to share costs and benefits was identified as one of the major barriers to collaborative commerce. To gain some basic understanding of the cost allocation issue in supply chain cooperation, we analyze several fundamental inventory centralization games: the single period inventory game with stochastic demand and quantity discount, the economic lot sizing game and the capacity investment game, by employing the cooperative game theory. In such games, a number of retailers may form joint ventures to build production facilities, make joint production (or place joint orders) and/or keep centralized inventories by taking advantage of economies of scale and/or risk pooling effects. The analysis of cost allocation in these games gives arise to a variety of challenging non-convex minimization problems, for which we develop interesting optimization techniques by exploiting the problem structures. 报告人简介:Xin Chen is an assistant professor at the University of Illinois at Urbana-Champaign.
