摘要:Empirical studies of service systems have shown that workers exhibit different service rates depending on their assigned workload. In contrast, staffing models typically assume a constant service rate. To address this issue, we model two commonly observed behavioral effects, speedup and slowdown, in a general way that allows us to study their joint impact on service staffing. We fit our behavioral model to a hospital dataset and show that both effects are present across a variety of department...

摘要:We consider a periodic review, single-stage inventory system with multiple demand classes and a fixed replenishment lead time. Inventory expediting is allowed to alleviate demand-supply mismatches. Priority demands are commonly used in practice to provide differentiated services for customers, and inventory expediting is an effective strategy to improve the service levels of high-priority demands. However, it is challenging to coordinate the inventory ordering, expediting and allocation decisi...

摘要:We consider a random number of strategic customers who compete for a limited stock of products, and decide whether to buy a product at full price now or at a discount price by waiting until the end of the selling season. This decision is not trivial, as waiting leads to not only a lower cost, but also less value due to a possible stockout caused by the limited product quantity. The equilibrium analysis of the competition game based on a theoretical model predicts that strategic customers wait ...

摘要:This study models a multi-player environment consisting of a grid operator responsible for meeting electricity demands, a photovoltaic (PV) manufacturer, customers who might install (solar) PV systems, and a regulator who must set an optimal feed-in tariff (FIT). The grid operator must meet exogenous electricity demand and also buy back all electricity (produced by PV systems) at the FIT set by the regulator. Customers decide whether or not to invest in a PV system. Adoption rates affect the m...

摘要:Supplier development and supplier integration are two deeply interconnected strategic tools that manufacturers often employ to improve the efficiency and competitiveness of their supply chains. This paper studies the interaction of these two strategic decisions in a competitive environment. Specifically, we consider a duopoly model where two supply chains, each consisting of one manufacturer and one supplier, sell substitutable products in the market. Each manufacturer orders components from i...

摘要:Coordinating contracts have been extensively researched in supply chain management. In this retrospect, we systematically review the profit allocation, decision sequence, and compliance aspects of these contracts. In addition to the existing concepts in the literature, we propose the notion of sample-path flexibility in profit allocation. Based on precise mathematical definitions, we develop structural properties and characterize sufficient conditions for flexibility in profit allocation, sequ...

摘要:This paper studies how a manufacturer should engage with a platform retailer and a traditional reseller. Our work is motivated by the emergence of increasingly powerful retail platforms in China's consumer electronics and appliances markets. The manufacturer pays a slotting fee and a portion of its sales revenue to the platform retailer in exchange for the opportunity to manage its own space within the retailer's store. The manufacturer can also sell its product to a traditional reseller there...

摘要:We investigate the scheduling practices of a medical school that must assign a cohort of students to a series of clinical rotations, while respecting both operational and quality-of-service requirements. Students become available to start clerkship progressively throughout the year and can complete rotations at hospitals in different geographic regions. Each hospital may offer a subset of the clinical rotations, with different start dates, capacities, and cost rates. We propose a novel network...

摘要:To manage chronic disease patients effectively, clinicians must know (i) how to monitor each patient (i.e., when to schedule the next visit and which tests to take), and (ii) how to control the disease (i.e., what levels of controllable risk factors will sufficiently slow progression). Our research addresses these questions simultaneously and provides the optimal solution to a novel linear quadratic Gaussian state space model. For the objective of minimizing the relative change in state over t...

摘要:Procurement auctions are widely used by governments and corporations to solicit bids for services and projects. Such auctions involve significant risk for the buyer, because the delivered quality is highly uncertain. We examine a multi-attribute procurement auction combined with a performance-based contract. In this setting, suppliers submit bids which include both price and promised quality. After the buyer awards the contract to the winning bidder with the highest score, the supplier exerts ...
