摘要：We consider a supply chain where a contract manufacturer (CM) serves a number of original equipment manufacturers (OEMs). Investment into productive resources is made before demand realization, hence the supply chain faces the risk of under- or overinvestment. The CM and OEMs differ in their forecast accuracy and in their resource pooling capabilities, leading to a disparity in their ability to minimize costs due to demand uncertainty. We consider two scenarios in which this risk is borne by t...

摘要：In a decentralized supply chain, with long-term competition between independent retailers facing random demands and buying from a common supplier, how should wholesale and retail prices be specified in an attempt to maximize supply-chain-wide profits? We show what types of coordination mechanisms allow the decentralized supply chain to generate aggregate expected profits equal to the optimal profits in a centralized system, and how the parameters of these (perfect) coordination schemes can be ...

摘要：The newsvendor model is designed to decide how much of a product to order when the product is to be sold over a short selling season with stochastic demand and there are no additional opportunities to replenish inventory. There are many practical situations that reasonably conform to those assumptions, but the traditional newsvendor model also assumes a fixed salvage value: all inventory left over at the end of the season is sold off at a fixed per-unit price. The fixed salvage value assumptio...

摘要：With the increased emphasis on the effective management of operational issues in supply chains, the timely delivery of products has become even more important. Companies have to quote attainable delivery dates and then meet these, or face large tardiness penalties. We study systems that can be modeled by single-machine scheduling problems with due date assignment and controllable job-processing times, which are either linear or convex functions of the amount of a continuously divisible and non...
