摘要：Service quality is an important attribute that is used to characterize many service systems. In this study, we examine a service system with two consecutive steps that have shared resources. The service process consists of a base service (first step in the process) followed by a second step that adds additional value. We first look at a social surplus maximizing service provider (SP) who decides the optimal service capacity and re-optimizes in response to changes in the speed of service of the...

摘要：We consider scheduling issues at Beycelik, a Turkish automotive stamping company that uses presses to give shape to metal sheets in order to produce auto parts. The problem concerns the minimization of the total completion time of job orders (i.e., makespan) during a planning horizon. This problem may be classified as a combined generalized flowshop and flexible flowshop problem with special characteristics. We show that the Stamping Scheduling Problem is NP-Hard. We develop an integer program...

摘要：There is currently no theory that explains the pattern of change in a plant's performance as it implements a lean program. Does it improve at a declining, increasing, or constant rate, or in some other pattern? We use empirical data from the implementation of the Volvo Group's lean program worldwide to develop a grounded theory to explain this pattern. We find that the pattern roughly follows an S-curve shape: as a plant progresses in its implementation of lean production, its operational perf...

摘要：High-tech organizations maintain a portfolio of R&D projects that address problems with different levels of complexity. These projects use different strategies to search for technological solutions. Projects refining existing products, processes, and technologies, for instance, employ a local search strategy to improve performance, while projects developing new products, processes, and technologies employ a distant search strategy. However, projects can shift in their levels of complexity due ...

摘要：By applying the state feedback principle of control theory, this study develops a state-feedback model that is capable of self-compensation and self-adjustment for inventory control. To be specific, under the state-feedback model, deviation between material order quantity and actual shipment can be dynamically adjusted in response to the actual shipment with the pole-placement state-feedback mechanism. As a result of this merit, the state-feedback model can ensure a more accurate order in each...

摘要：Outsourcing stretches supply chains longer with added contract manufacturers responsible for the manufacturing of parts and final products. Should a firm change its quality management approach as its supply chain becomes longer with outsourced manufacturing? This paper studies a brand owner's optimal choice between two commonly used quality management approaches: an inspection-based approach and an external failure-based approach, in two supply chains - a dyadic supply chain and a multi-level ...

摘要：Gray markets are unauthorized channels that distribute a branded product without the manufacturer's permission. Since gray markets are not officially sanctioned by the manufacturer, their existence is assumed to hurt the manufacturer. Yet manufacturers sometimes tolerate or even encourage gray market activities. We investigate the incentives of a manufacturer and its authorized retailer to engage in (or tolerate) gray markets. The firms need to consider the trade-off between the positive effec...

摘要：This study examines the effects of a relatively new channel structure on prices and sales in a large department store, which in recent years has switched the management of many of its product categories from a traditional retailer-managed system to a manufacturer-managed system. We find that the change caused overall retail prices to decrease. However, there was significant heterogeneity in the response across brands. In the cell phone category, brands with high market shares and inelastic dem...

摘要：Product design has increasingly been recognized as an important source of competitive advantage. This study empirically estimates the impact of effective design on the market value of the firm. We use a firm's receipt of a product design award as a proxy for its design effectiveness. Based on data from 264 announcements of design awards given to commercialized products between 1998 and 2011, we find that award announcements are associated with statistically significant positive stock market re...

摘要：We consider subscription-based rental organizations, such as Netflix, where the satisfaction of customers depends on the availability of requested products. Recommender systems, in a DVD-rental context, are typically used to help customers in finding the right movies for them. Accordingly, the focus in recommender system research is generally on making better predictions of users' ratings. In contrast, we focus on better utilizing these rating estimates in the operations of DVD-rental firms. W...
