摘要：Problem definition: In many resource scheduling problems for services with scheduled starting and completion times (e.g., airport gate assignment), a common approach is to maintain appropriate buffer between successive services assigned to a common resource. With a large buffer, the chances of a crossing (i.e., a flight arriving later than the succeeding one at the gate) will be significantly reduced. This approach is often preferred over more sophisticated stochastic mixed-integer programming...

摘要：Problem definition: Modern technologies have made it viable for firms to lower the costs of switching on and off production in response to market changes. In this paper, we explore how production start-stop flexibility impacts joint operating policies, financing, and investment timing decisions. Methodology/results: We develop a continuous-time, optimal stopping model in which equity holders of the firm make operational decisions regarding pausing and restarting production as well as when to d...

摘要：Problem definition: Guided delegation, a practice in which companies provide guidelines when delegating supplier management to tier 1 firms, is a common practice in managing complex supply chains. We study the benefits and risks of this approach in a three-tier supply chain setting consisting of a buying firm, a tier 1 contract manufacturer, and tier 2 suppliers, where responsibility risk stems from the tier 2 suppliers. We analyze the buyer's profit and the supply chain's responsibility risk ...

摘要：Problem definition: Customer reviews are essential to online marketplaces. However, reviews typically vary; ratings of a product or service are rarely the same. In many service marketplaces, including the ones for solar panel installations, supply-side participants are active. That is, a seller must make a proposal to serve each customer. In such marketplaces, it is not clear how (or if) the dispersion in customer reviews affects the seller activity level and number of matches in the marketpla...

摘要：Problem definition: Motivated by a platelet inventory management problem, we study a fixed lifetime perishable inventory management problem under a general demand process. Determining an optimal ordering policy for perishable inventory systems is particularly challenging because of the well-known curse of dimensionality. Approximation policies with worst-case performance bounds have been developed in the literature for perishable inventory systems. However, using real data, we observe that the...

摘要：Problem definition: Education technology innovations, such as massive open online course (MOOC) platforms, could potentially enable a more inclusive learning environment by delivering education to traditionally disadvantaged learners, like women. However, inclusivity does not necessarily translate into equal treatment on the platform. We investigate whether female and male learners benefit equally from forum discussions- typically the only form of interaction available-in online learning platf...

摘要：Problem definition: The narrow definition of supply chain finance (SCF) as a financing scheme for accounts receivables fails to capture the knowledge creation of MSOM research scholars of the last 25 years who labored in the area under this label. A redefined definition of the research-and-application field, under the acronym integrated SCF (iSCF), better reflects the interplay of operational, financial, and risk management decisions our scholars and practitioners care about. The foundational ...

摘要：Problem definition:A critical decision made by firms is whether to adopt a responsive supply chain (prioritizing speed) or an efficient supply chain (prioritizing cost). We consider the environmental implications of this choice, distinguishing between responsiveness achieved via three pathways: responsive offshore supply chains increase speed by using expedited production and distribution methods; responsive nearshore supply chains increase speed by reducing the physical distance between sourc...

摘要：Problem definition: Energy storage has become an indispensable part of power distribution systems, necessitating prudent investment decisions. We analyze an energy storage facility location problem and compare the benefits of centralized storage (adjacent to a central energy generation site) versus distributed storage (localized at demand sites). This problem encompasses optimizing storage capacities across all locations, with the objective of minimizing the total storage investment and energy...
