摘要：We consider a firm's sourcing problem from one reliable supplier and one unreliable supplier in two price-setting scenarios. In the committed pricing scenario, the firm makes the pricing decision before the supply uncertainty is resolved. In the responsive pricing scenario, the firm ' s pricing decision is made after the supply uncertainty is resolved. For the committed pricing scenario, we develop a condition on supply uncertainty that guarantees the unimodality of the firm's objective functi...

摘要：The current state of outpatient healthcare delivery is characterized by capacity shortages and long waits for appointments, yet a substantial fraction of valuable doctors' capacity is wasted due to no-shows. In this study, we examine the effect of wait to appointment on patient flow, specifically on a patient's decision to schedule an appointment and to subsequently arrive to it. These two decisions may be dependent, as appointments are more likely to be scheduled by patients who are more pati...

摘要：Gray markets are created by unauthorized retailers selling manufacturer's branded products. Similar to international gray markets, domestic gray markets are a growing phenomenon whose impact on supply chains is not clear. We consider a supply chain with one manufacturer and several authorized retailers who face a newsvendor problem and a domestic gray market. While a gray market provides an opportunity for retailers to clear their excess inventory (inventory-correction effect), it also can be ...

摘要：This study investigates the interactions between a manufacturer's information acquisition and quality disclosure strategies in a supply chain setting in which the manufacturer privately knows his product quality but is uncertain about consumer preferences. We argue that the manufacturer should treat his information acquisition and quality disclosure decisions as an integrated process because these decisions can significantly influence a retailer's rational inferences about product quality and ...

摘要：We present a framework to describe and analyze operational risk in financial services from an operations management perspective, focusing in particular on process design, process management, and human behavior aspects. The financial services industry differs from other service industries in ways that affect the nature of the operational risks it is subject to. In recent decades, many books and papers have focused on operational risk in financial services; however, this literature has focused m...

摘要：We study an inventory management mechanism that uses two stochastic programs (SPs), the customary one-period assemble-to-order (ATO) model and its relaxation, to conceive control policies for dynamic ATO systems. We introduce a class of ATO systems, those that possess what we call a chained BOM. We prove that having a chained BOM is a sufficient condition for both SPs to be L? convex in the first-stage decision variables. We show by examples the necessity of the condition. For ATO systems with...

摘要：We model a supply chain consisting of a supplier and multiple retailers facing deterministic demand. We denote some retailers as strategic in the sense that given the supplier inventory information, they will implement the optimal stocking policy by incorporating such information. On the other hand, some retailers are denoted as naive in the sense that they ignore supply information and resort to a simplistic ordering policy. Naive retailers learn the optimal policy over time and adjust their ...

摘要：A growing number of companies install wind and solar generators in their energy-intensive facilities to attain low-carbonmanufacturing operations. However, there is a lack of methodological studies on operating large manufacturing facilities with intermittent power. This study presents a multi-period, production-inventory planning model in a multi-plant manufacturing system powered with onsite and grid renewable energy. Our goal is to determine the production quantity, the stock level, and the...

摘要：Research on buyer-supplier relationships (BSRs) has often focused on only one side of the relationship and, thus, has tended to overlook asymmetries. Yet, a buyer (supplier) may often deal with a bigger supplier (buyer) or one that has higher levels of trust, respect, and reciprocity. Therefore, we examined how two types of asymmetriessize and relational capitalaffect perceived opportunism and performance. We used dyadic data from 106 buyers and their matched suppliers gathered from a survey a...

摘要：Can peer-to-peer (P2P) marketplaces benefit traditional supply chains when consumers may experience valuation risk? P2P marketplaces can mitigate consumers' risk by allowing them to trade mismatched goods; yet, they also impose a threat to retailers and their suppliers as they compete over consumers. Further, do profit-maximizing marketplaces always extract the entire consumer surplus from the online trades? Our two-period model highlights the effects introduced by P2P marketplaces while accou...
