摘要：We consider the scheduling of ground station support times to low Earth orbit (LEO) satellites with overlapping visibilities. LEO satellites typically complete a revolution around the Earth in less than four hours at an altitude of a few hundred miles and are part of the critical infrastructure for natural resource management, crop yield estimation, meteorology, flood control, communication, and space research. Because these satellites are quite expensive to launch and operate, utilizing them ...

摘要：We develop a general model for software development process and propose a policy to manage system coordination using system fault reports (e.g., interface inconsistencies, parameter mismatches, etc.). These reports are used to determine the timing of coordination activities that remove faults. We show that under an optimal policy, coordination should be performed only if a threshold fault count has been exceeded. We apply the policy to software development processes and compare the management ...

摘要：Due to the proliferation of electronic commerce and the development of Internet technologies, many firms have considered new pricing-inventory models. In this paper, we study the role of stockless (i.e., zeroinventory) operations in online retailing by a considering duopoly competition in which two retailers compete to maximize profit by jointly optimizing their pricing and inventory decisions. In our model, the retailers are allowed to choose either an in-stock policy or stockless operations ...

摘要：Buyers often find that obtaining complete information about suppliers is costly. In such scenarios, there is a trade-off between the costs of obtaining information and the benefits that accrue to the owners of such information. There are also various ways in which the missing information can be obtained or inferred. In this paper, we compare the efficiency of obtaining information via the classical mechanism design approach, which relies on the information available before the contracts are de...

摘要：We report on a cross-sectional and longitudinal comparison of European distribution centers in the Netherlands. European distribution centers are responsible for the distribution of a manufacturer's (mostly Asian or American) products over customers in a large part of Europe, the Middle East, and Africa, often with strict service-level agreements. In total, 65 physical warehouses, containing 140 European, Asian, and American European distribution center operations, in combination with differen...

摘要：We consider replenishment decisions for a constant rate demand environment from a supplier with uncertain lead times. We study the potential use of a flexible backup supplier as an emergency response to accurate lead-time information arriving at (or close after) the beginning of the demand interval and well after an original order with the stochastic lead-time supplier has been placed. The emergency response decisions involve whether to order and how much from the flexible backup supplier, wit...

摘要：Vendor managed inventory systems are becoming increasingly popular. An important issue in implementing a vendor managed inventory scheme is the contracting terms that dictate the ownership of the inventory and the responsibility of inventory replenishment decisions. Thus the performance of a vendor managed system crucially depends on these terms and on how inventory-related costs are shared in a supply chain. We consider a system where a manufacturer supplies a single product to a retailer who...
