摘要：We examine two time-related incentive project management contracts (C1 and C2 contracts) when the manager conducts a reverse auction. Under the C1 contract, the contractor with the lowest bid price wins; however, the manager imposes a linear and symmetric incentive/disincentive for early/late completion according to a pre-specified due date. Under the C2 contract, the winning contractor has the lowest composite score that is based on the quoted price and the quoted due date; however, in additi...

摘要：We study the logistics problem faced by Regional Branches (RBs) of a central bank in managing the currency supply under security concerns. While making banknote supply decisions to Sub-Branches (SBs), the management of RB must achieve two goals simultaneously: (i) guarantee that each SB has sufficient inventories of all denominations of banknotes to satisfy the demands from all commercial banks within its service area, and (ii) control the annual spending on this banknote supply operation. Due...

摘要：In developing countries, farmers lack information for making informed production, manufacturing/selling decisions to improve their earnings. To alleviate poverty, various non-governmental organizations (NGOs) and for-profit companies have developed different ways to distribute information about market price, crop advisory and farming technique to farmers. We investigate a fundamental question: will information create economic value for farmers? We construct a stylized model in which farmers fa...

摘要：We analyze the benefit of production/service capacity sharing for a set of independent firms. Firms have the choice of either operating their own production/service facilities or investing in a facility that is shared. Facilities are modeled as queueing systems with finite service rates. Firms decide on capacity levels (the service rate) to minimize delay costs and capacity investment costs possibly subject to service-level constraints on delay. If firms decide to operate a shared facility the...

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...
