摘要：Product expiration is an important problem in the consumer-packaged-goods industry eroding profits and generating substantial waste. We propose that shelf space selection can be an operational lever to control expiration of perishable inventory. To this end, we first explain the conditions under which shelf space impacts expiration then develop a method to determine the appropriate level of shelf space which incorporates this impact. We formulate a shelf space selection problem for a single pr...

摘要：We investigate the association between continuity of care mechanisms and a patient's risk of readmission in the context of one chronic condition, heart failure. We define continuity of care as the level of consistency across patient care episodes. We dynamically measure continuity of individual referring provider; continuity of physical location, which links multiple individual providers; and continuity of Accountable Care Organization, which spans a variety of individual and institutional pro...

摘要：We study the classic assortment optimization problem in which a retailer seeks the revenue maximizing set of products to offer to each arriving customer. This study relates two variants of this assortment problem: the space constrained assortment problem, in which the retailer has a limit on the total space of the offered assortment, and the fixed cost assortment problem, in which the retailer incurs a fixed cost for each offered product. In particular, we develop an approximation scheme for t...

摘要：When designing an assortment, a fundamental trade-off exists between estimating consumer behavior more precisely and solving the corresponding optimization problem efficiently. For instance, a mixture of logit model can closely approximate any random-utility choice model; however, it is not suitable for optimization when the number of customer segments and the number of products considered are large. As many companies are using big data and marketing analytics toward microsegmenting consumers,...

摘要：Conspicuous consumption of status goods signals consumers' status and grants status value to them. In this article, we examine how firms selling status goods make vertical line extension decisions when they take consumers' status preferences into account. Analyzing an incumbent's vertical line extensions when it faces a threat of entry, we find that status preferences can make unprofitable extensions profitable. Moreover, without status preferences, an incumbent can introduce line extensions t...

摘要：Retail inventories have been consistently dropping, relative to sales, since the 1990s. Whether these lean inventory developments translate to better retailer operational performance is still an open question. We empirically examine associations between inventory leanness and operational efficiency for a sample of public US retailers from 2000 to 2013. Via a stochastic frontier analysis that accounts for retailer heterogeneity and time parameters, we find support for the hypothesis that operat...

摘要：We consider an integrated multinational firm (MNF) who produces a product in a low-tax country and sells it in a high-tax country. The global firm faces the decision of whether to sell the product (and at what price) to an external rival in the retail market who has an alternative outside sourcing option. Using a Cournot competition model, we show that two salient elements of the global tax planning-namely the tax rate disparity and the regulatory restrictions on transfer pricing between the M...

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...

摘要：This special issue implores us to address sustainability from the lens of emerging economies and the role that innovation can play in this context. We posit that, for sustainable operations research to be relevant in the context of emerging economies, it needs to incorporate social concerns and conditions of underserved populations, with an emphasis on inclusion and equity. Especially important for addressing social concerns of these populations will be product/service innovation, process/busi...

摘要：This paper studies the priority pricing problem for a single-server queueing system with two priority classes in which customers have different sensitivities to delay. The system makes a fixed-delay announcement to inform arriving customers of the expected delay for each class, whereupon each customer must decide which class to join. Any customer who joins the priority class is charged a fixed priority price. Our examination of customers' joining behavior under any given priority prices reveal...
