摘要：This study seeks to conceptualize supply chains that use funding from large donors or governments for long-term recovery following a disaster, or more generally, for economic development in a region. We call these development-aid supply chains (DASC) distinct from commercial or humanitarian supply chains. With little available formally on DASCs in the literature, we carried out a field study across five solar lantern supply chains in Haiti set up for recovery following the massive 2010 earthqu...

摘要：Supplier non-performance is an ever present problem for an original equipment manufacturer (OEM) buyer and past survey-based research has shown that increasing supplier competition adversely affects their performance. Using a reverse auction setting in which supplier competition is determined by number (n) of participating suppliers (bidders), we show how buyer's exposure to supplier non-performance risk is influenced by n. In particular, we characterize conditions under which supplier non-per...

摘要：Most automobile manufacturers use franchised dealers to distribute their products and to perform sales-related and after-sales services. However, the link between dealers' service quality and manufacturer performance is not well understood. Some studies suggest that these services' quality affects product sales, repeat sales, and brand reputation. Others posit that dealer services are a commodity, and their quality may only affect sales in the extremes. We constructed data representing sales a...

摘要：We study a generalized operating room planning and scheduling (GORPS) problem at the Toronto General Hospital (TGH) in Ontario, Canada. GORPS allocates elective patients and resources (i.e., operating rooms, surgeons, anesthetists) to days, assigns resources to patients, and sequences patients in each day. We consider patients' due-date, resource eligibility, heterogeneous performances of resources, downstream unit requirements, and lag times between resources. The goal is to create a weekly s...

摘要：This study develops a dynamic model to examine how a firm selling new non-durable experience goods can signal its high quality with dynamic spot-pricing or price commitment. Since consumers who buy and use the product will learn its quality, the firm's early period price will endogenously determine the number of informed consumers in the later period. Without price commitment, the high-quality firm prefers the pooling outcome in the first period, generating enough informed consumers to induce ...

摘要：Inventory optimization approaches typically optimize steady-state performance, but do not consider the transition of an initial state to the optimized state. In this study, we address this transition. Our research is motivated by a company that implemented an improved inventory policy for its spare parts division. The improved policy suggested new base stock levels for the majority of the parts. For parts with increased base stock levels, inventory increases were realized after the part lead t...

摘要：The Centers for Medicare and Medicaid Services (CMS) has introduced several Episode-based Payment Models. Episodes are combinations of pre-acute, acute, and post-acute services for particular medical conditions. During the year, CMS pays hospitals according to historical norms. At the end of the year, these payments are reconciled against a target price, resulting in either a gain or a loss for the hospital. The hospital may also realize gains or losses from its internal operations. It may inc...

摘要：In this study, as an alternative to the surplus utility, we propose a performance-price-ratio (PPR) utility and specialize the customer choice model with a PPR maximization criterion. With the PPR-based choice model, we investigate a pricing game between retailers in a competitive market. Through transferring the decision variable from price to performance-price ratio, the first-order condition of the game becomes a linear equation system, which enables us to develop a closed-form equilibrium ...

摘要：Aid organizations choose their service providers through reverse auctions to decrease their operational costs, and many of them award the contracts to the lowest bidders, which often leads to aggressive bidding practices and compromised service quality. This is known as the abnormally low bids (ALBs) problem in public procurement. An ALB is defined as an unrealistically low bid submitted to win an auction, an amount at which the auctioned service cannot be provided reliably. The current litera...

摘要：The growing population in cities and booming e-commerce activities create huge demand for urban last-mile delivery, exerting intense pressure on the cities' well-being. To keep congestion and pollution under control, a consolidator can operate an urban consolidation center (UCC) to bundle shipments from multiple carriers before the last-mile delivery. Alternatively, the consolidator can operate a peer-to-peer platform for the carriers to share delivery capacity. We provide guidance for the con...
