摘要：This study is based on the analysis of field data on the revenues and patient flows that we collected on all adult emergency department (ED) visits to a level-1 trauma, tertiary referral center. Our objective was to provide researchers in operations a rich overview of the processes, resources, and metrics of financial and operations performance in the ED. We analyze how patients, physicians, hospitals/physician employer groups, and payers are party to the value created and financial workflow o...

摘要：Prior research documents the value of network relationships to firm behavior but is relatively silent on how networks influence opportunism in distribution channels. Focusing on a common type of distribution networks in which multiple distributors serve a single, dominant supplier, this study moves beyond a dyadic view to examine how a focal distributor's relational and structural embeddedness in such a distribution network influences its opportunism toward the dominant supplier. In particular...

摘要：We seek to conceptualize social responsibility for operations management (OM) research to develop a social responsibility lens through which to view operations. To do so, we first consider the corporate social responsibility, sustainability, as well as the bottom-of-the-pyramid and shared value approaches and identify three challenges to developing such a lens: selecting the level of analysis, tackling the huge multitude of objectives, and developing theoretical underpinnings. We then propose ...

摘要：Motivated by the observation that durability ratings of automobile manufacturers are not necessarily linked to the proportion of leasing but tend to decrease with the density of their dealer networks, we explore the interactions between channel structure (direct interaction with consumers vs. through an intermediary(ies)) and mode of operations (leasing vs. selling) and their implications for a manufacturer's willingness to invest in making her product more durable. Using a manufacturer who le...

摘要：In procurement auctions, the object for sale is a contract, bidders are suppliers, and the bid taker is a buyer. The suppliers bidding for the contract are usually the current supplier (the incumbent) and a group of potential new suppliers (the entrants). As the buyer has an ongoing relationship with the incumbent, he needs to adjust the bids of the entrants to include non-price attributes, such as the switching costs. The buyer can run a scoring auction, in which suppliers compete on the adju...

摘要：We consider a patient admission problem to a hospital with multiple resource constraints (e. g., OR and beds) and a stochastic evolution of patient care requirements across multiple resources. There is a small but significant proportion of emergency patients who arrive randomly and have to be accepted at the hospital. However, the hospital needs to decide whether to accept, postpone, or even reject the admission from a random stream of non-emergency elective patients. We formulate the control ...

摘要：To alleviate poverty in developing countries, governments and non-governmental organizations disseminate two types of information: (i) agricultural advice to enable farmers to improve their operations (cost reduction, quality improvement, and process yield increase); and (ii) market information about future price/demand to enable farmers to make better production planning decisions. This information is usually disseminated free of charge. While farmers can use the market information to improve...

摘要：This study analyzes optimal replenishment policies that minimize expected discounted cost of multi-product stochastic inventory systems. The distinguishing feature of the multi-product inventory system that we analyze is the existence of correlated demand and joint-replenishment costs across multiple products. Our objective is to understand the structure of the optimal policy and use this structure to construct a heuristic method that can solve problems set in real-world sizes/dimensions. Usin...
