摘要：The U.S. economy is already dominated by service and information-intensive industries in terms of both gross national product and jobs, and these trends are visible in all major world economies. These economic shifts are driven by productivity changes, which today often depend on new information and communication technologies. These changes can be thought of as service industrialization, which underlies productivity improvements. Industrialization is, in turn, closely related to the design and...

摘要：Motivated by collaboration with a global spare parts service provider, we consider a two-echelon inventory system with multiple local warehouses, a so-called support warehouse, and a central warehouse with ample capacity. In case of stock-outs, the local warehouses can receive emergency shipments from the support warehouse or the central warehouse at an extra cost. Our focus is on using information on orders in the replenishment pipeline, i.e., pipeline information, to achieve cost-efficient p...

摘要：We consider the partitioning of care types into wings from the perspective of a hospital administrator who wishes to optimize the use of a fixed number of beds that provide services for heterogeneous care types. The hospital administrator decides on the number of wings to form, the number of beds to allocate to each wing, and the set of care types to assign to each wing to maximize the total utility to the hospital. The administrator faces an inherent trade-off between forming large wings to p...

摘要：We consider a manager who invests in knowledge development of a product and a process design team as well as knowledge transfer between teams throughout a new product development (NPD) project. Knowledge development at a particular time (e.g., prototyping and experimentation) increases a team's level of knowledge at that time. In contrast, the recipient's benefits from knowledge transfer may be lagged because of the difficulties in articulating and documenting knowledge as well as the challeng...

摘要：Early infant diagnosis (EID) programs in many resource-limited settings are aimed at diagnosing infants born to HIV-infected mothers. Because of the complexity of the diagnostic technology, EID programs are often highly centralized with few laboratories testing blood samples from a large network of health facilities. This leads to long diagnostic delays and consequent failure of patients to collect results in a timely manner. Several point-of-care (POC) devices that provide rapid diagnosis wit...

摘要：The bullwhip effect and production smoothing appear antithetical because their empirical tests oppose one another: production variability exceeding sales variability for bullwhip, and vice versa for smoothing. But this is a false dichotomy. We distinguish between the phenomena with a new production smoothing measure, which estimates how much more variable production would be absent production volatility costs. We apply our metric to an automotive manufacturing sample comprising 162 car models ...

摘要：This paper explores the merits of hedging stochastic input costs (i.e., reducing the risk of adverse changes in costs) in a decentralized, risk-neutral supply chain. Specifically, we consider a generalized version of the well-known selling-to-the-newsvendor model in which both the upstream and the downstream firms face stochastic input costs. The firms' operations are intertwined-i.e., the downstream buyer depends on the upstream supplier for delivery and the supplier depends on the buyer for ...

摘要：We analyze a model of rental and return process where limited inventory of a product is rented to two customer classes that differ in their return behavior and penalty costs. The rental demand is a decreasing function of time. We consider two cases: where a demand that is not met is lost and where an unmet demand returns. We show that to minimize penalty cost, the optimal allocation policy may give priority to different classes at different points in time and may decline lower-class demand for...

摘要：Consider a buyer who would like to procure certain products for the current period and the underlying technologies so that he can become a supplier and compete with current suppliers in the future market. One potential procurement mechanism for such a buyer is to bundle the procurement project with technology acquisition. We propose a dynamic stochastic game-theoretic model that analyzes the optimal technology offer strategies of the asymmetric suppliers and highlights how the size of the curr...
