  摘要：In this work, we study the assortment planning games in which multiple retailers interact in the market. Each retailer owns some of the products and their goal is to select a subset of products, that is, an assortment to offer to the customers so as to maximize their expected revenue. The purchase behavior of the customer is assumed to follow the Markov chain choice model. We consider two types of assortment games under the Markov chain choice model-a competitive game and a cooperative game. I...
• Beyond Retail Stores: Managing Product Proliferation along the Supply Chain AI翻译

  摘要：Product proliferation occurs in supply chains when manufacturers respond to diverse market needs by trying to produce a range of products from a limited variety of raw materials. In such a setting, delaying the point of the proliferation helps manufacturers improve their responsiveness by postponing the ordering decisions of the final products until there is partial or full resolution of the demand uncertainty. This strategy can be implemented in two different ways: (i) redesigning the operati...
• Consumer Surplus Under Demand Uncertainty AI翻译

  摘要：Consumer Surplus is traditionally defined for the case where demand is a deterministic function of the price. However, demand is usually stochastic and hence stock-outs can occur. Policy makers who consider the impact of different regulations on Consumer Surplus often ignore the impact of demand uncertainty. We present a definition of the Consumer Surplus under stochastic demand. We then use this definition to study the impact of demand and supply uncertainty on consumers in several cases (add...

  摘要：In this paper, we discuss fleet size decisions of an equipment rental firm. The availability of the rental equipment depends on the fleet size of the firm and has a direct impact on its profitability. In our setting, we allow for partial backordering, reneging, and finite commitment capacity. Moreover, we explicitly consider the breakdown possibility of the available equipment fleet. We develop an efficient recursive algorithm to solve the underlying two-dimensional stochastic single-player mo...
• Join, balk, or jettison? The effect of flexibility and ranking knowledge in systems with batch arrivals AI翻译

  摘要：Families that visit theme parks like Disneyland are debating on two aspects when they try to determine whether they prefer to join an activity of interest or would rather balk: (1) Is it better to join or balk as a group or allow the flexibility to get separated and jettison some members? and (2) Will it make any difference if they set a ranking among themselves beforehand as to who will be served first, second, etc.? We tackle the effect of flexibility and ranking knowledge and answer the abo...
• Optimal Scale-Up of HIV Treatment Programs in Resource-Limited Settings Under Supply Uncertainty AI翻译

  摘要：This study is motivated by the challenges faced by clinics in sub-Saharan Africa in allocating scarce and unreliable supply of antiretroviral drugs (ARVs) among a large pool of eligible patients. Existing discussion of ARV allocation is focused on qualitative rules for prioritizing certain socioeconomic and demographic patient segments over others at the national level. However, such prioritization rules are of limited utility in providing quantitative guidance on scaling up of treatment progr...
• Stochastic Sequential Allocations for Creative Crowdsourcing AI翻译

  摘要：Creative crowdsourcing is an innovative online business model in which a platform marshals independent professionals (e.g., designers) to conduct creative work projects. Typically, clients submit project requests stochastically to a platform which possesses a pool of registered designers. For each submitted project, designers decide whether to participate and attempt to submit a design, and the client either chooses a winner among all submissions, or rejects them all, based on subjective crite...
• Pioneering role of the Production and Operations Management in promoting empirical research in operations management AI翻译

  摘要：We describe the pioneering role of the Production and Operations Management (POM) in promoting empirical research in innovation, operations, and supply chain management. We also review and discuss the most influential empirical papers published in POM based on each paper's Google Scholar citation counts. We selected the top 200 cited papers from the 2085 papers published or forthcoming in POM to identify the most influential empirical papers. We classify these 200 papers into three categories:...
• Supply chain fairness AI翻译

  摘要：Supply chain fairness refers to the practices that members in a supply chain treat each other. Due to imperfections of a competitive market, some members could exploit their positions or circumstances that enabled them to gain excessive advantage over others. Such unfair practices could be in the form of unfair prices, unfair trade, or unfair pay. The COVID-19 pandemic has exposed many vulnerabilities of global supply chains, but it also unearthed unfair supply chain practices. Yet, some firms...

  摘要：Reduction in hospital readmissions has long been identified as a target area for healthcare public policy reform by the US government. In October 2012, the Affordable Care Act (ACA) established the Hospital Readmissions Reduction Program (HRRP) program, which requires the Centers for Medicare and Medicaid Services to reduce payments to hospitals with excess readmissions. Even with recent changes in ACA, the HRRP program is still in place. In this study, we empirically examine the effectiveness...
