摘要：In this study, we consider a two-retailer, one-supplier supply chain in which retailers satisfy excess demand by offering to directly ship out-of-stock items on an expedited basis at no extra cost to customers. This practice is referred to as the fast-ship option. We consider two scenarios along with the fast-ship option. In the first scenario, retailers transship when out of stock, whereas in the second scenario, they do not. If they do not transship, some customers may perform the search on ...

摘要：This paper studies two-stage lot-sizing problems with uncertain demand, where lost sales, backlogging and no backlogging are all considered. To handle the ambiguity in the probability distribution of demand, distributionally robust models are established only based on mean-covariance information about the distribution. Based on shortest path reformulations of lot-sizing problems, we prove that robust solutions can be obtained by solving mixed 0-1 conic quadratic programs (CQPs) with mean-risk ...

摘要：We consider a make-to-stock, finite-capacity production system with setup cost and delay-sensitive customers. To balance the setup and inventory related costs, the production manager adopts a two-critical-number control policy, where the production starts when the number of waiting customers reaches a certain level and shuts down when a certain quantity of inventory has accumulated. Once the production is set up, the unit production time follows an exponential distribution. Potential customers...

摘要：Operations Management (OM) research on organizational culture has to change to be able to inform practice. Currently, organizational culture research in OM is largely confined to narrow topical and methodological niches and culture is most frequently used as an explanatory variable in quantitative, survey-based research. We argue that the relegation of culture to this niche is due to self-imposed methodological blinders that hobble the OM field. We then present four research imperatives to rei...

摘要：Sourcing from multiple suppliers with different characteristics is common in practice for various reasons. This paper studies a dynamic procurement planning problem in which the firm can replenish inventory from a fast and a slow supplier, both with uncertain capacities. The optimal policy is characterized by two reorder points, one for each supplier. Whenever the pre-order inventory level is below the reorder point, a replenishment order is issued to the corresponding supplier. Interestingly,...

摘要：Despite the importance of knowledge sharing between supply chain partners, supplier motivation to share remains largely unexplored. This study examines the role of buyer power in supplier motivation to share knowledge. Applying a multi-method, sequential research design, case studies followed by a scenario-based experiment, we find buyer expert power increases supplier motivation to share, while the use of coercive power decreases this motivation. We also find that supplier dependence has a co...

摘要：Recent research on decision framing has shown that (i) there are multiple types of framing effects and (ii) the context of the decision can influence framing effects. This research examines decision framing effects in inventory control contexts by questioning the assumption of procedure invariance, that preference should not be impacted by how options are presented to a supply chain manager making an inventory control decision. Study 1 uses three single-shot decision experiments to establish t...

摘要：In this study, we consider the issue of preannouncing or not preannouncing the development of a new product. Our research is motivated by contrasting views in the literature and varying actions observed in practice. We develop and analyze a game theoretic model that examines the effect of a firm's preannouncement of its product development. Our model is based on a durable goods duopoly market with profit-maximizing firms. The first firm is an innovator who initially begins developing the produ...

摘要：We investigate the optimal strategies for firms to invest in their suppliers when the benefits of such investments can spillover to other firms who also source from the same suppliers. We consider two Bayesian firms that can invest in improving the quality of their shared supplier; the firms do not have complete information on the true quality of the supplier, but they update their beliefs based on the supplier's performance. We formulate the problem as an investment game and obtain Markov per...
