摘要：We apply service-operations-management concepts to improve the efficiency and equity of voting systems. Recent elections in the United States and elsewhere have been plagued by long lines, excessive waiting times, and perceptions of unfairness. We build models for the waiting lines at voting precincts using both traditional steady-state queueing methods and simulation models. We develop solution methods to allocate voting machines optimally to precincts. Our objective functions consider both t...

摘要：In contrast to the Pollution Haven Hypothesis, the Trade-Up Hypothesis holds that international integration helps improve firms' environmental performance in developing countries. Using firm-level data from Shanghai, this article examines how international linkages, in the form of foreign direct investment or international trade, affect firms' environmental compliance and performance. We find that firms with international linkage via ownership exhibit better compliance with environmental regul...

摘要：A supply chain management (SCM) system comprises many subsystems, including forecasting, order management, supplier management, procurement, production planning and control, warehousing and distribution, and product development. Demand-supply mismatches (DSMs) could indicate that some or all of these subsystems are not working as expected, creating uncertainties about the overall capabilities and effectiveness of the SCM system, which can increase firm risk. This article documents the effect o...

摘要：Motivated by supply chain collaborations in practice, we introduce a class of cost-coalitional problems, which are based on a priori information about the cost faced by each agent in each set that it could belong to. Our focus is on problems with decreasingly monotonic coalitional costs. In this class of problems, we study the effects of giving and receiving when there exist players whose participation in an alliance always contributes to the savings of all alliance members (we refer to these ...

摘要：Operations management methods have been applied profitably to a wide range of technology portfolio management problems, but have been slow to be adopted by governments and policy makers. We develop a framework that allows us to apply such techniques to a large and important public policy problem: energy technology R&D portfolio management under climate change. We apply a multi-model approach, implementing probabilistic data derived from expert elicitations into a novel stochastic programming v...

摘要：We consider an original equipment manufacturer (OEM) who faces competition from an independent remanufacturer (IR). The OEM decides the quality of the new product, which also determines the quality of the competing remanufactured product. The OEM and the IR then competitively determine their production quantities. We explicitly characterize how the OEM competes with the IR in equilibrium. Specifically, we show that the OEM relies more on quality as a strategic lever when it has a stronger comp...

摘要：The value of demand information underlies many supply chain strategies that aim at better matching supply and demand. This study reports on the results of a laboratory experiment designed to estimate the behavioral value of demand information. Relative to the commonly assumed benchmark of a rational risk-neutral decision maker, we find that decision makers are consistently willing to pay too much for the option to eliminate the risk of supply not matching demand. Contrary to intuition, we show...

摘要：This research investigates the value of category captainship (a management practice in which a retailer relies on a manufacturer for recommendations regarding strategic category management decisions) in retail supply chains. We consider a setting where the scope of category management is limited to assortment decisions and demand enhancing activities. We assume that the retailer selects a category captain among multiple competing manufacturers with privately known capabilities for driving cate...
