摘要：This study considers the scheduling of limited resources to a large number of jobs (e.g., medical treatment) with uncertain lifetimes and service times, in the aftermath of a mass casualty incident. Jobs are subject to triage at time zero, and placed into a number of classes. Our goal is to maximize the expected number of job completions. We propose an effective yet simple index policy based on Whittle's restless bandits approach. The problem concerned features a finite and uncertain time hori...

摘要：Direct-Store-Delivery (DSD) is an arrangement in which a retailer allows a manufacturer to execute in-store operations such as shelf replenishments. This paper studies the economic drivers and implications of DSD for retailers and manufacturers. We consider a distribution channel where two competing manufacturers sell their products via a shelf-space constrained retailer. The shelf space allocated to each product affects the cost associated with in-store operations. The retailer can offer DSD ...

摘要：To enhance performance, buying firms often use supplier governance mechanisms, such as explicit contracts, to coordinate efforts. Yet, it is unclear how these governance mechanisms would perform in extralegal exchanges, whereby suppliers may renege on the contract with little or no legal recourse. Furthermore, there is a paucity of studies examining these extralegal exchanges in the presence of an external market willing to pay higher prices, thus tempting suppliers to renege on existing agree...

摘要：This study provides key arguments and contributions of Kuhn (1970) concerning paradigms, paradigm shifts, and scientific revolutions. We provide interpretations of Kuhn's (1970) key ideas and concepts, especially as they relate to business management research. We conclude by considering the practical implications of paradigms and paradigm shifts for contemporary business management researchers and suggest that ethical rules of conversation are at least as critical for the health of a scientifi...

摘要：In this study, we explore firm-level perspectives from four types of organizations on how collaborative relationships are viewed, strengthened, and applied in responding to disasters. We focus on the perspective of four types of organizations operating at the forefront of the response to major hurricanes in the United States. These include government agencies and non-governmental organizations (NGOs) at the regional and local levels. We analyze qualitative evidence from managers and directors ...

摘要：In this study, we consider a company that uses two channels for trading: long-term contracts and spot markets. With a quantity flexibility long-term contract, the buyer commits to purchasing at least as much as the minimum order quantity and is able to reserve capacity with the forward contract supplier up to the maximum order quantity in each period at a predetermined price. Through the spot market, the buyer can order or sell inventory at an uncertain future spot price without quantity limit...

摘要：The timing of vulnerability disclosures (by vulnerability discoverers) has significant implications for software producers and users. Immediate disclosure (before a patch becomes available) could result in exploits with subsequent harm to installed systems. Therefore, it is important to understand the determinants of this timing. In this study, we investigate the impacts of (i) the perception of the vulnerability discoverer about the software producer, (ii) the type of vulnerable software, and...

摘要：We investigate price and stock competition between two retailers selling to a market with uncertain size. Prior to knowing the actual market size, retailers choose stocking quantities before prices under prestocking but adopt the reverse sequence under prepricing. After the actual market size is realized, each customer chooses to purchase from a retailer to maximize utility. Each retailer satisfies its local demand up to availability. A customer with unmet demand at the local retailer may cont...

摘要：We analyze production and capacity utilization strategies in a supply chain where individual components can be made either at a shared in-house manufacturing facility or at dedicated facilities of external subcontractors. The manufacturer and the subcontractor differ in terms of costs, production capacities, rates, and service level capabilities. Using Markov decision process models, we determine the optimal policy and characterize its structure. We derive the set of conditions that partitions...
