摘要：Many retailers are increasingly turning to home delivery as a new arena of operational competition. This study controlled for industry by investigating the online home delivery grocery business, and an analysis of 1,919 customers of home delivery grocers identified four groups of online customers based on reasons for selecting this service. These four groups were next linked to operational execution in terms of service, product, and Internet quality, and found to vary in predicable ways. Subse...

摘要：Elwood Spencer Buffa, a pioneer in production and operations management (P/OM), passed away in the summer of 2005, leaving his legacy behind. During his academic career Buffa made lasting contributions to teaching and research of P/OM. We review those contributions and their impact on the evolution of the P/OM discipline.

摘要：Motivated by an oilfield services industry case study, we investigate the dynamic behavior of customized service supply chains by developing a two-stage serial staffing model. Each stage holds no finished goods inventory, but rather only backlogs that can be managed by adjusting staffing levels. We develop optimal control policies to balance backlog costs against hiring and firing personnel costs-assuming shared backlog information-under both centralized and decentralized control. We examine w...

摘要：Diverse businesses, such as garbage collection, retail banking, and management consulting are often tied together under the heading of services, based on little more than a perception that then are intangible and do not manufacture anything. Such definitions inadequately identify managerial and operational implications common among, and unique to, services. We present a Unified Services Theory (UST) to clearly delineate service processes from non-service processes and to identify key commonali...

摘要：We develop a new, unified approach to treating continuous-time stochastic inventory problems with both the average and discounted cost criteria. The approach involves the development of an adjusted discounted cycle cost formula, which has an appealing intuitive interpretation. We show for the first time that an (s, S) policy is optimal in the case of demand having a compound Poisson component as well as a constant rate component. Our demand structure simultaneously generalizes the classical EO...
