Research Initiation: Multiproduct Inventory Models with Demand Substitution

需求替代在实践中很常见， 制造业、分销业和服务业。 例 出现向下替代结构的是钢铁行业 强度更大的钢梁可以代替 力量较小。 该项目将制定一个总体框架 它确定了最优策略的属性， 算法来计算大规模的最佳策略， 真实的生活问题。 很少有研究直接涉及 需求替代，他们中的大多数只处理特定的 两种产品的案例。 模型和求解技术是 在解决安全库存等问题时很有用 地点，并分配卡的客户在汽车租赁 行业，以及航空业的收益率问题。

Demand substitutions are common in practice, in the manufacturing, distributions and service industries. An example where downward substitution structure arises is the steel industry where steel beams of greater strength can substitute for beams of lesser strength. This project will develop a general framework which identifies properties of the optimal policies and efficient algorithms to calculate the optimal policies for large size and real life problems. There are few studies that deal directly with the problem of demand substitutions, and most of them deal with only the specific case of two products. The models and solution techniques are useful in solving a variety of problems like safety stock locations, and allocations of cards to customers in the car rental industry, and the yield problem in the airline industry.
