摘要：This paper studies an innovative agricultural partnership model in the dairy industry. In developing regions, farmers are constrained by limited resources, while it is costly for an enterprise to set up new facilities and raise dairy animals all on its own. Under the partnership model, dairy animals are raised by individual farmers during the maturing stage and then by the enterprise during the milking stage. This can lower the enterprise's investment cost, ensure milk quality, and also expand...

摘要：We examine the implications of proximity to a physical store in offline-online retail competition where online disutility costs, which encompasses factors such as trust in the seller, returns, and after-sales support, are important. Building on classical models, we consider a traditional retailer's expansion online, benefitting from the physical store's presence in serving customers online. Our innovation is to allow online disutility costs to be mitigated if the purchase is from a dual-channe...

摘要：In today's increasingly interconnected world, co-opetition has emerged as a new business practice among many high-tech firms. The boundaries between cooperation and competition becomes vague, and rivals engage in collaborative activities. This study develops an analytical model to investigate the dual sourcing decision of the original equipment manufacturer (OEM) in the presence of a competitive supplier (i.e., frenemy) as well as a non-competitive supplier who nevertheless suffers from unreli...

摘要：This paper studies bargaining in two-sided supply chain networks where manufacturers on the demand side purchase an input from suppliers on the supply side. The manufacturers may have heterogeneous valuations on the input sold by the suppliers. In such a supply chain network, a manufacturer and a supplier must have a business relationship or link to bargain and trade with each other. However, a firm on one side of the supply chain network might not have a business relationship with every firm ...

摘要：The present study investigates the benefit of joint decision making regarding whole blood collection and platelet production at a blood center. We consider a blood center that faces two types of platelet demands, differing in their freshness requirements and shortage penalty costs. We fully characterize the structure of the optimal policy regarding whole blood collection, platelet production, and inventory issuing, rationing and disposal. We find that the optimal platelet production quantity i...

摘要：In recent years, the drive to contain health care costs has increased scrutiny of the traditional mode of delivering primary care where a patient is treated only by his primary care physician. In particular, greater reliance on non-physician providers has been suggested as a lower-cost alternative to the traditional set-up. In this study, we consider a homogeneous patient panel treated by a solo primary care physician and develop a new model of patient health dynamics in which the health state...

摘要：We consider an M/M/1 queueing system with a pay-for-priority option, and study customers' joint decisions between joining/balking and pay-for-priority. The equilibrium strategies are thus two-dimensional. First, we fully characterize the equilibrium structure and identify the Pareto-dominant strategies of such a game analytically, under both the observable and unobservable settings. Interestingly, the equilibrium structure, the system throughput, and the service provider's optimal price for pr...

摘要：We study a supply chain of a manufacturer selling to two asymmetric retailers engaged in inventory (order quantity) competition in the presence of demand uncertainty and an exogenously given retail price. The effective demand of each retailer includes its primary demand and reallocated demand from its competitor. We model two salient features causing asymmetry: (i) the weak retailer is capital-constrained and (ii) the bargaining power of the dominant retailer implies that it enjoys a lower who...

摘要：There is extensive academic research examining why firms adopt environmental management practices (EMPs), reflecting an increasing focus on firm environmental activity in research and practice. However, there is little understanding of why firms vary within and across industries in the number of EMPs they adopt (EMP adoption). In this study, we seek to identify the sources of variation and quantify the relative importance of each source. Using Hierarchical Linear Modeling (HLM) and a 12-year p...

摘要：The purpose of this paper is to investigate the learning from rare events and the knowledge management process involved, which presents a significant challenge to many organizations. This is primarily attributed to the inability to interpret these events in a systematic and rich manner, which this paper seeks to address. We start by summarizing the relevant literature on humanitarian operations management (HOM), outlining the evolution of the socio-technical disaster lifecycle and its relation...
