摘要：We address the scheduling of operations in a robotic cell that produces multiple part-types. The objective is to obtain a cyclic schedule-a sequence of robot moves and an ordering of the parts-that minimizes the long-run average time to produce a part or, equivalently, maximizes the throughput. We consider two different models that are currently used in practice. The first is a single-gripper cell with a unit-capacity output buffer at each machine. The second is a bufferless dual-gripper cell....

摘要：We consider a component acquisition problem for a contract manufacturer who faces a one-time stochastic demand for a single product consisting of a number of components. Components can be ordered early at normal prices before the demand is revealed, or they can be replenished later at higher prices due to expediting. In addition, the customer pays a price for the final product that is nonincreasing in the delivery lead time to discourage late delivery. We propose a cost-minimization model and ...

摘要：In a recent paper we introduced the queue-and-idleness ratio (QIR) family of routing rules for many-server service systems with multiple customer classes and server pools. A newly available server serves the customer from the head of the queue of the class (from among those the server is eligible to serve) whose queue length most exceeds a specified proportion of the total queue length. Under fairly general conditions, QIR produces an important state-space collapse as the total arrival rate an...

摘要：We study how rework routing together with wage and piece-rate compensation can strengthen incentives for quality. Traditionally, rework is assigned back to the agent who generates the defect (in a self-routing scheme) or to another agent dedicated to rework (in a dedicated routing scheme). In contrast, a novel cross-routing scheme allocates rework to a parallel agent performing both new jobs and rework. The agent who passes quality inspection or completes rework receives the piece rate paid pe...

摘要：his paper contributes to the literature on enterprise resource planning (ERP) by pursuing two objectives. First, it identifies configurations of ERP adopters that have similar needs and develop similar competencies. Second, it tests the hypothesis that, to maximize benefits from their ERP projects, organizations should align their ERP competence-building mechanisms with the ERP needs that arise from their operational environment. The analysis of a sample of manufacturing companies that impleme...

摘要：We study a supply chain where an upstream supplier auctions his inventory or capacity as a bundle. The importance of this setting is twofold: From a practical point of view, there are several examples, both in manufacturing (e. g., auctioning the capacity of a wafer fabrication facility) and service industries (e. g., auctioning the sponsorship of a website), where a supplier's capacity is sold as a single piece; from a theoretical side, it highlights the information asymmetry introduced on th...

摘要：We study dynamic pricing and inventory control of substitute products for a retailer who faces a long supply lead time and a short selling season. Within a multinomial logit model of consumer choice over substitutes, we develop a stochastic dynamic programming formulation and derive the optimal dynamic pricing policy. We prove that dynamic pricing converges to static pricing as inventory levels of all variates approach the number of remaining selling periods (assuming at most one customer arri...

摘要：When a customer orders online, an online retailer assigns the order to one or more of its warehouses and/or drop-shippers to minimize procurement and transportation costs based on the available current information. However, this assignment is necessarily myopic because it cannot account for any subsequent customer orders or future inventory replenishment. We examine the benefits of periodically reevaluating these real-time assignments. We construct near-optimal heuristics for the reassignment ...

摘要：In this paper, we describe data collected from five U. S. properties of a major hotel chain that can be used to benchmark the performance of choice-based revenue management (RM) algorithms. The process used to collect this data illustrates subtle complexities involved in extracting product availability information from current RM systems and sheds new light on practical issues that need to be addressed to successfully implement choice-based RM systems. The data described in this paper is publi...

摘要：This paper studies a buyback contract in the Stackelberg framework of a manufacturer (leader) selling to a price-setting newsvendor retailer (follower). Using an analytical model that focuses on a multiplicative demand form, we generalize previous results and produce new structural insights. A novel transformation technique first enables us to establish the unimodality of the profit functions for both channel partners, under relatively mild assumptions. Further analysis identifies the necessar...
