摘要：The Production and Operations Management Society (POMS) and Production and Operations Management (POM) have developed new initiatives with these objectives: (1) to disseminate managerial insights of articles published in POM to practitioners, MBA students, and participants in executive development programs; (2) to solicit descriptions of current and emerging problems from practitioners and share them with academics; and (3) to recognize academic research based on direct work with practitioners.

摘要：In determining their operations strategy, a firm chooses whether to be responsive or efficient. For firms competing in a market with uncertain demand and varying intensity of substitutability for the competitor's product, we characterize the responsive or efficient choice in equilibrium. To focus first on the competitive implications, we study a model where a firm can choose to be responsive at no additional fixed or marginal cost. We find that competing firms will choose the same configuratio...

摘要：We study an overbooking model for scheduling arrivals at a medical facility under no-show behavior, with patients having different no-show probabilities and different weights. The scheduler has to assign the patients to time slots in such a way that she minimizes the expected weighted sum of the patients' waiting times and the doctor's idle time and overtime. We first consider the static problem, where the set of patients to be scheduled and their characteristics are known in advance. We parti...

摘要：The relationship between emissions reduction and firm financial performance has been studied with mixed results. We consider potential sources of this ambiguity by examining announcements of voluntary emissions reduction (VER) from 1990 to 2009. We measure the stock market reaction associated with VER announcements to estimate the effects of time, emissions type, and whether the reduction was announced ex ante or ex post. We find that the market reaction to VER significantly decreased over tim...

摘要：We examine the role of knowledge diversity among unit members on an organizational unit's productivity. Utilizing a proprietary data set of corrective maintenance tasks from a large software-services firm, we investigate the impact of two key within-unit diversity metrics: interpersonal diversity and intrapersonal diversity. We analyze the independent influence of interpersonal diversity and the interactive influence of interpersonal diversity and intrapersonal diversity on organizational unit...

摘要：We consider a supplier selling to multiple retailers using one of two constant wholesale pricing strategies: a uniform wholesale price (UWP) vs. a retailer-specific wholesale price (RSWP). In line with the prior literature in economics, our initial finding is that as long as retailers are asymmetric, then (a) the supplier and less efficient retailer would prefer the RSWP strategy and (b) the more efficient retailer would prefer the UWP strategy. By examining the total profits of the supply cha...

摘要：We consider a pricing and short-term capacity allocation problem in the presence of buyers with orders for bundles of products. The supplier's objective is to maximize her net profit, computed as the difference between the revenue generated through sales of products and the production and inventory holding costs. The objective of each buyer is similarly profit maximization, where a buyer's profit is computed as the difference between the time-dependent utility of the product bundle he plans to...

摘要：Extended enterprises face many challenges in managing the product quality of their suppliers. Consequently characterizing the quality risk posed by value-chain partners has become increasingly important. There have been several recent efforts to develop frameworks for rating the quality risk posed by suppliers. We develop an analytical model to examine the impact of such quality ratings on suppliers, manufacturers, and social welfare. While it might seem that quality ratings would benefit high...

摘要：We study a firm's optimal transshipment problem considering the impacts of setup costs for transshipment and demand distribution shapes. We assume that the demand follows a three-point distribution, which changes from a degenerate distribution, to a unimodal distribution, and to a bimodal distribution as the demand shape parameter increases. We find that as the demand shape parameter increases, the optimal transshipment strategy changes from no transshipment to transshipment, and finally to no...
