摘要：This study characterizes the class of Pareto optimal returns policies between a manufacturer and a retailer who receives consumer returns. The manufacturer may take a costly hidden action that reduces the expected number of products returned by consumers, which when realized is hidden information known only to the retailer. When faced with consumer returns, the retailer must decide whether to send the product back to the manufacturer, who harvests a low salvage value, or to engage in costly re...

摘要：Although project portfolio management has been an active research area over the past 50 years, budget allocation models that consider competition are sparse. Faced with the competition, firms contemplating budget allocation for their project portfolio cannot limit their attention to the returns from their projects' target markets, as is the case for monopoly firms, but must also anticipate the competitive effects on these returns. Assuming firms allocate their budgets between projects offering...

摘要：Although online shopping is becoming popular, consumers who are unsure about whether to buy a product may find it advantageous to visit a brick-and-mortar retail store to first examine the product before purchasing it. But, after browsing at the store, consumers have the option of switching to an e-tailer to purchase the item at a cheaper price rather than buying at the store. Recent business press refers to this browse-and-switch behavior as showrooming, and attributes to it the declining pro...

摘要：We develop an inventory placement model in the context of general multi-echelon supply chains where the delivery lead time promised to the customer must be respected. The delivery lead time is calculated based on the available stocks of the different input and output products in the different facilities and takes into account the purchasing lead times, the manufacturing lead times, and the transportation lead times. We assume finite manufacturing capacities and consider the interactions of man...

摘要：Increasingly many firms have started to implement programs intended to improve the workers' health and the psychosocial work-environment, as well as other attributes of labor quality. Motivated by the need for evaluating to what extent the programs affect a firm's productivity performance, this study discusses a model for analyzing the contribution of labor quality attributes toward firm productivity. To assess the contribution from the labor quality attributes, we model firm productivity as t...

摘要：We consider coordination issues in supply chains where supplier's production process is subject to random yield losses. For a simple supply chain with a single supplier and retailer facing deterministic demand, a pay back contract which has the retailer paying a discount price for the supplier's excess units can provide the right incentive for the supplier to increase his production size and achieve coordination. Building upon this result, we consider coordination issues for two other supply c...

摘要：For large multi-division firms, coordinating procurement policies across multiple divisions to leverage volume discounts from suppliers based on firm-wide purchasing power can yield millions of dollars of savings in procurement costs. Coordinated procurement entails deciding which suppliers to use to meet each division's purchasing needs and sourcing preferences so as to minimize overall purchasing, logistics, and operational costs. Motivated by this tactical procurement planning problem facin...

摘要：In this study, we investigate the bullwhip effect in China using data on over 1200 companies listed on the Shanghai and Shenzhen stock exchanges from 2002 to 2009. Specifically, we estimate the ratio of the volatility of production to the volatility of demand as a proxy for the bullwhip effect. Our results show that more than two-thirds of the companies we studied exhibit the bullwhip effect. We also find that several hypotheses proposed in the existing literature are supported by firm-level d...

摘要：The Genesis of this Special Issue came from the Board of the POMS College on Humanitarian Operations and Crisis Management (HO&CM). It was seen as a necessary initiative to define the field and examine research opportunities. This Special Issue shows that humanitarian operations pose challenges for P/OM researchers and practitioners that differ markedly from those of conventional supply chains associated with profitable enterprises. On the basis of the eight articles in this Special Issue, we ...
