摘要：When facing supply uncertainty caused by exogenous factors such as adverse weather conditions, firms diversify their supply sources following the wisdom of not holding all eggs in one basket. We study a firm that decides on investment and production levels of two unreliable but substitutable resources. Applying real options thinking, production decisions account for actual supply capabilities, whereas investment decisions are made in advance. To model triangular supply and demand correlations,...

摘要：With increasing frequency, firms are locating their operations in disparate countries with distinct national cultures and languages. This study develops and empirically tests hypotheses relating an operation's process compliance performance to (1) the presence of a language difference between the location of the operation and that of headquarters and (2) the national culture of the location of the operation and that of headquarters. Employing an international sample of pharmaceutical manufactu...

摘要：We show simple yet optimal results to update the inventory/capacity levels, expected profit, fill rates, and service levels of substitutable resources in response to an updating of the mean demand forecasts for the resources. We find that a change in the mean demand of one resource does not affect the optimal inventory level of any other resource. The results are obtained for demands with location-scale distribution, and for a revenue structure satisfying a triangle property such that the mana...

摘要：For infectious diseases like tuberculosis and HIV, treatment adherence plays an important role in treatment effectiveness and epidemic control. Studies of some infectious diseases indicate that patients who live closer to their health facilities maintain higher adherence; however, most models ignore the heterogeneity of patients' adherence. Clinics must balance knowledge about adherence with epidemic growth when creating successful treatment programs. We develop an optimization model that inte...

摘要：It is common for a firm to make use of multiple suppliers of different delivery lead times, reliabilities, and costs. In this study, we are concerned with the joint pricing and inventory control problem for such a firm that has a quick-response supplier and a regular supplier that both suffer random disruptions, and faces price-sensitive random demands. We aim at characterizing the optimal ordering and pricing policies in each period over a planning horizon, and analyzing the impacts of supply...

摘要：Retailers are increasingly adopting a dual-format model. In addition to acting as traditional merchants (buying and reselling goods), these retailers provide a platform for third-party (3P) sellers to access and compete for the same customers. We investigate the strategic rationale for a retailer to introduce a 3P marketplace. Our analysis provides insights into the growing prevalence of 3P marketplaces. We show that by committing to having an active 3P marketplace, the retailer creates an out...

摘要：Floods are the most frequent category of disasters worldwide. Among all geographic regions, Asia has suffered the most. While there are several ongoing humanitarian efforts and initiatives, we believe there is a new opportunity to coordinate last mile humanitarian efforts in the event of a flood using micro-retailers. Because micro-retailers are the last mile nodes in traditional retail supply chains in many Asian countries, we propose the use of social enterprise to buttress these supply chai...

摘要：We address the problem of assigning airline customer service agents (CSAs) to tasks related to departing flights, such as selling tickets and collecting boarding cards, at an international terminal of a large airport. The airline specifies minimum and target levels of staff and required (or desired) types and levels of skills for each location in each time period. The assignment problem is complicated by staff heterogeneity, time required for moves between locations, and lunch and rest-break r...

摘要：Forecast sharing among trading partners lies at the heart of many collaborative and contractual supply chain management efforts. Even though it has been praised in both academic and practitioner circles for its critical role in increasing demand visibility, some concerns remain: The first one is related to the credibility of forecast sharing, and the second is the fear that it may turn into a competitive disadvantage and induce suppliers to increase their price offerings. In this study, we exp...
