  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...
• A Network-Based Formulation for Scheduling Clinical Rotations AI翻译

  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...
• Dynamic Monitoring and Control of Irreversible Chronic Diseases with Application to Glaucoma AI翻译

  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...
• Optimal Feed-In Tariff Policies: The Impact of Market Structure and Technology Characteristics AI翻译

  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...
• Slow First, Fast Later: Temporal Speed-Up in Service Episodes of Finite Duration AI翻译

  摘要：Many service environments such as outpatient departments comprise repeated episodes of finite duration wherein customers arriving during an episode must be served before the end of that episode. Scheduling resources and customer arrivals in such settings involves trading off customer wait against resources' time and effort. We hypothesize that this trade-off leads to a slow first, fast later pattern of system speed, which allows build-up of inventory earlier for more efficient utilization of f...
• Profit Allocation, Decision Sequence and Compliance Aspects of Coordinating Contracts: A Retrospect AI翻译

  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...
• Channel Selection and Contracting in the Presence of a Retail Platform AI翻译

  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...
• Decision Biases of Strategic Customers with Private Product-Value Information: An Experimental Study AI翻译

  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：Cloud providers such as Amazon, IBM, and Microsoft are leasing their computing resources to various businesses providing them an alternative to investing in expensive hardware. Although recent information systems research has examined pricing-related issues in cloud computing, several important questions still remain. For example, how should buyers decide on the capacity portfolio of private and public clouds? What is the impact of the buyer's demand uncertainty on the capacity portfolio decis...
