• Sourcing with Deferred Payment and Inspection under Supplier Product Adulteration Risk AI翻译

  摘要：We study the deferred payment and inspection mechanisms for mitigating supplier product adulteration, with endogenous procurement decision and general defect discovery process. We first derive the optimal deferred payment contract, which reveals that either entire or partial deferral can arise, depending on the moral hazard severity and the information accumulation rate. Because of the supplier's incentive to adulterate, the optimal procurement quantity under deferred payment generally is smal...
• A Dynamic Disaggregation Approach to Approximate Linear Programs for Network Revenue Management AI翻译
  作者：Vossen, Thomas W. M.; Zhang, Dan

  摘要：The linear programming approach to approximate dynamic programming has received considerable attention in the recent network revenue management (RM) literature. A major challenge of the approach lies in solving the resulting approximate linear programs (ALPs), which often have a huge number of constraints and/or variables. Starting from a recently developed compact affine ALP for network RM, we develop a novel dynamic disaggregation algorithm to solve the problem, which combines column and con...
• The Timing of Capacity Investment with Lead Times: When Do Firms Act in Unison? AI翻译
  作者：Anderson, Edward James; Yang, Shu-Jung Sunny

  摘要：We study competitive capacity investment for the emergence of a new market. Firms may invest either in capacity leading demand or in capacity lagging demand at different costs. We show how the lead time and other operational factors including volume flexibility, existing capacity, and demand uncertainty impact equilibrium outcomes. Our results indicate that a type of bandwagon behavior is the most likely equilibrium outcome: if both firms are going to invest, then they are most likely to act i...
• Managing Perishables with Time and Temperature History AI翻译

  摘要：We address the use and value of time and temperature information to manage perishables in the context of a retailer that sells a random lifetime product subject to stochastic demand and lost sales. The product's lifetime is largely determined by the temperature history and the flow time through the supply chain. We compare the case in which information on flow time and temperature history is available and used for inventory management to a base case in which such information is not available. ...
• Impulse Balance and Multiple-Period Feedback in the Newsvendor Game AI翻译
  作者：Ockenfels, Axel; Selten, Reinhard

  摘要：Human subjects in the newsvendor game place suboptimal orders: orders are typically between the expected profit-maximizing quantity and mean demand (pull-to-center bias). In previous work, we have shown that impulse balance equilibrium (IBE), which is based on a simple ex post rationality principle along with an equilibrium condition, can predict ordering decisions in the laboratory. In this study, we extend IBE to standing orders and multiple-period feedback and show that it predicts-in line ...
• Economic Manufacturing Quantity and Its Integrating Implications AI翻译
  作者：Moily, Jaya P.
  作者单位：University System of Maryland; University of Baltimore
  摘要：Several contradictions are noted among the Economic Order Quantity (EOQ), Just-In-Time (JIT), and Optimized Production Technology (OPT) approaches and the economic framework for profit maximization. A fundamental model referred to as the Economic Manufacturing Quantity (EMO) is developed and examined for its integrating implications for the three approaches. An implication for the classic EOQ approach is that the balance between setup and inventory carrying costs is valid when a production fac...
• Online Manufacturer Referral to Heterogeneous Retailers AI翻译

  摘要：Since the development of the Internet, thousands of manufacturers have been referring consumers visiting their websites to some or all of their retailers. Through a model with one manufacturer and two heterogeneous retailers, we investigate whether it is an equilibrium for the manufacturer to refer consumers exclusively to a retailer or nonexclusively to both retailers. Our analysis indicates that nonexclusive referral is the manufacturer's equilibrium choice if the referral segment market siz...
• Competition and Coordination in a Two-Channel Supply Chain AI翻译

  摘要：We study competition and coordination in a supply chain in which a single supplier both operates a direct channel and sells its product through multiple differentiated retailers. We study analytically the supply chain with symmetric retailers and find that the supplier prefers to have as many retailers as possible in the market, even if the retailers' equilibrium retail price is lower than that of the supplier, and even if the number of retailers and their cost or market advantage prevent sale...
• An Integrated Text Analytic Framework for Product Defect Discovery AI翻译

  摘要：The recent surge in the usage of social media has created an enormous amount of user-generated content (UGC). While there are streams of research that seek to mine UGC, these research studies seldom tackle analysis of this textual content from a quality management perspective. In this study, we synthesize existing research studies on text mining and propose an integrated text analytic framework for product defect discovery. The framework effectively leverages rich social media content and quan...
• Dynamic Pricing of New Services in Subscription Markets AI翻译

  摘要：We analyze the dynamic price discrimination strategies of a monopolist who offers new services on a subscription basis. Access to customers' subscription histories permits the monopolist to design pricing policies that can be based on customers' past purchase behavior, and on the time period in which they made their purchases. Uncertainty regarding the value of new features, and heterogeneity in consumers' valuation for existing features, creates inter-temporal incentives that influence both p...
