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 industries where firms perform dangerous (but necessary) operations, liability costsdue to potential harm to third partiescan be significant. Firms may therefore find it optimal to exit the market, and this may lead to an inefficiently low number of incumbents. A social planner can discourage exit by offering appropriately designed subsidies. Ex ante subsidies defray the costs associated with making operations safer (e.g., funds to subsidize the purchase of safety equipment). Ex post subsid...

摘要：Cross-training workers is one of the most efficient ways of achieving flexibility in manufacturing and service systems for increasing responsiveness to demand variability. However, it is generally the case that cross-trained employees are not as productive on a specific task as employees who were originally trained for that task. Also, the productivity of the cross-trained workers depends on when they are cross-trained. In this work, we consider a two-stage model to analyze the effects of vari...

摘要：The major research methodologies deployed for operations management (OM) research include analytical modeling research (e.g., optimization, computational, and simulation models), quantitative empirical research (e.g., surveys, and event studies), and case study research. In recent years, there is an emerging trend toward employing a multi-methodological approach (MMA) to address complex and intriguing OM issues. The MMA helps derive solid research results and boost the scientific merit of OM r...

摘要：We model the global vehicle supply chain of an International Humanitarian Organization (IHO) with a dynamic hub location model across monthly periods. We use actual vehicle data from the International Federation of the Red Cross to feed our model and provide insights into IHO secondary support demand. We find that secondary support demand for items such as vehicles is different from primary beneficiary demand for items such as water and food. When considering disaster response and development ...

摘要：Downstream firms increasingly recognize the importance of integrating social and environmental concerns with their businesses. As a consequence, they urge to create incentives for their suppliers to invest in corporate social responsibility (CSR) activities. Contracts to provide these incentives are rarely observed in practice. If not totally absent, contracts may be incomplete, in that unforeseen contingencies or some CSR attributes that are difficult to measure may not be included in the con...
