  摘要：We consider a company that schedules the tasks of its projects to maximize their expected net present value (ENPV) when tasks may fail. The failure of any task terminates the project immediately. We show that for projects with certain decreasing failure rates, the ENPV optimization problem can be solved using a linear program. The main focus of our work is on how constant task failure rates contribute to decreasing project risk as tasks are completed. Under constant task failure rate, earlier ...
• Category Inventory Planning With Service Level Requirements and Dynamic Substitutions AI翻译

  摘要：We study a single-period inventory planning problem for a category of substitutable products. This is an important practical problem facing category managers who have to maintain high service levels for constantly expanding product catalogs. We formulate the problem as a stochastic optimization model that minimizes the total stocking cost subject to service level requirements, which consist of product-specific and category-wide targets for inventory availability (ready rates) through the selli...
• One Size Fits All? The Differential Impact of Online Reviews and Coupons AI翻译

  摘要：Using a unique dataset that includes individually identifiable consumer online browsing and purchase data in the restaurant industry, this paper examines how individual consumer shopping characteristics and product characteristics moderate the effect of online reviews on individual consumer choice based on information search theory and signaling theory. We find that different dimensions of reviews have distinctive impacts on consumers with different information search needs and behaviors based...
• Return Window Decision in A Distribution Channel AI翻译

  摘要：This study investigates a firm's return window decision in a distribution channel. Conventional wisdom posits that compared to a centralized channel, a decentralized channel induces worse services (e.g., a shorter return window) because of double marginalization. We build a model consisting of one manufacturer, one retailer, and consumers who are heterogeneous in their willingness-to-pay (WTP) for product quality. Counterintuitively, we find that the return window can be longer in a decentrali...
• An Efficient Algorithm for Dynamic Pricing Using a Graphical Representation AI翻译

  摘要：We study a multi-period, multi-item dynamic pricing problem faced by a retailer. The objective is to maximize the total profit by choosing prices, while satisfying several business rules. The strength of our work lies in our graphical model reformulation, which allows us to use ideas from combinatorial optimization. We do not make any assumptions on the structure of the demand function. The complexity of our method depends linearly on the number of time periods but is exponential in the memory...
• Assessing Impacts of Store and Salesperson Dimensions of Retail Service Quality on Consumer Returns AI翻译

  摘要：This study contributes to the understanding of consumer return behavior by examining associations between in-store customer shopping experiences and subsequent customer returns. Return rates can vary a great deal across stores within a company and across salespersons within a store. We empirically examine returns across these two levels with respect to three retail service quality dimensions: salesperson friendliness, salesperson competence, and store environment. We conduct a detailed analysi...
• Location-Routing with Conflicting Objectives: Coordinating eBeam Phytosanitary Treatment and Distribution of Mexican Import Commodities AI翻译

  摘要：We study a generalized location-routing problem in which the key decisions are made by supply chain partners with conflicting objectives. The context of our problem is the irradiation by electron beam (eBeam) of fresh produce imported from Mexico to reduce the threat of insects and pests to the U.S. agriculture. Because too few irradiation facilities exist to serve the current demand, we focus on two parties to be coordinated: the eBeam Services Provider, who will choose the facilities' locati...
• On the Non-Equivalence of Trade-ins and Upgrades in the Presence of Framing Effect: Experimental Evidence and Implications for Theory AI翻译
  作者：Mahmoudzadeh, Mahdi
  作者单位：University System of Georgia; Georgia Institute of Technology
  摘要：Manufacturers of durable goods often buy back older versions of their products from customers to encourage them to switch to improved versions and to create control over product return streams in their closed-loop systems. Classical models and conventional wisdom have long ignored that the framing of these buyback schemes, whether through trade-ins or upgrades, can matter for theory. Using the reference-point shift mechanism, we provide experimental evidence that the alternative frames are not...
• Sourcing and Procurement Cost Allocation in Multi-Division Firms AI翻译
  作者：Fang, Fang; Natarajan, Harihara Prasad

  摘要：Through Central Procurement Organizations (CPOs), large firms with multiple divisions have begun adopting a center-led sourcing approach that allows firms to centralize strategic sourcing activities, while permitting decentralized execution by divisions, allowing the firm to leverage large purchase volumes with vendors. This new center-led procurement environment has brought a new decision requirement: How should a CPO select vendors for each division's requirements to minimize the firm's tota...
• Coordinating Lot Sizing Decisions Under Bilateral Information Asymmetry AI翻译

  摘要：We consider inventory management decisions when manufacturing and warehousing are controlled by independent entities. The latter possess private information that affects their choices and are allowed to communicate via a mediator who attempts to streamline their decisions without restricting their freedom. The mediator designs a mechanism based on quantity discounts to minimize the overall system costs, attempting to reach a win-win situation for both entities. Using the Revelation Principle, ...
