• A Model of Consumer Inertia with Applications to Dynamic Pricing AI翻译

  摘要：This paper introduces a decision model of consumer inertia. Consumers exhibit inertia when they have an inherent bias to delay purchases. Inertia may induce consumers to wait even when it is optimal to buy immediately. We embed our decision model within a dynamic pricing context. There is a firm that sells a fixed capacity over two time periods to an uncertain number of both rational and inertial consumers. We find that consumer inertia has both positive and negative effects on profits: it dec...

  摘要：Information delays exist in an inventory system when it takes time to collect, process, validate, and transmit inventory/demand data. A general framework is developed in this paper to describe information flows in an inventory system with information delays. We characterize the sufficient statistics for making optimal decisions. When the ordering cost is linear, the optimality of a state-dependent base-stock policy is established even when information flows are allowed to cross over time. Addi...
• E-Business: A Review of Research Published in Production and Operations Management (1992-2008) AI翻译

  摘要：We review, classify, consolidate, and synthesize the contributions to the expanding field of e-business that have been published in Production and Operations Management. We classify e-business research in the following four categories: (1) e-auctions, (2) radio frequency identification, (3) e-business system design, and (4) competition, conflict, collaboration, and coordination (C4 in e-business). We identify important research themes, research methodologies, and research techniques within eac...
• Managing White-Collar Work: An Operations-Oriented Survey AI翻译

  摘要：Although white-collar work is of vast importance to the economy, the operations management (OM) literature has focused largely on traditional blue-collar work. In an effort to stimulate more OM research into the design, control, and management of white-collar work systems, this paper provides a systematic review of disparate streams of research relevant to understanding white-collar work from an operations perspective. Our review classifies research according to its relevance to white-collar w...
• Static and Dynamic Pricing of Excess Capacity in a Make-to-Order Environment AI翻译

  摘要：We consider a make-to-order manufacturer that serves two customer classes: core customers who pay a fixed negotiated price, and fill-in'' customers who make submittal decisions based on the current price set by the firm. Using a Markovian queueing model, we determine how much the firm can gain by explicitly accounting for the status of its production facility in making pricing decisions. Specifically, we examine three pricing policies: (1) static, state-independent pricing, (2) constant pricin...
• Demand Forecast Sharing in Supply Chains AI翻译

  摘要：This paper examines the incentives of a manufacturer and a retailer to share their demand forecasts. The demand at the retailer is a linearly decreasing function of price. The manufacturer sets the wholesale price first, and the retailer sets the retail price after observing the wholesale price. Both players set their prices based on their forecasts of demand. In the make-to-order scenario, the manufacturer sets the production quantity after observing the actual demand; in the make-to-stock sc...
• Conditional Monte Carlo Gradient Estimation in Economic Design of Control Limits AI翻译

  摘要：The economic approach to determining the optimal control limits of control charts requires estimating the gradient of the expected cost function. Simulation is a very general methodology for estimating the expected costs, but for estimating the gradient, straightforward finite difference estimators can be inefficient. We demonstrate an alternative approach based on smoothed perturbation analysis (SPA), also known as conditional Monte Carlo. Numerical results and consequent design insights are ...
• The Role of Slotting Fees in the Coordination of Assortment Decisions AI翻译
  作者：Aydin, Goeker; Hausman, Warren H.
  作者单位：University of Michigan System; University of Michigan; Stanford University
  摘要：Large numbers of new products introduced annually by manufacturers may strain the relationship between retailers and manufacturers regarding assortments carried by retailers. For example, many retailers in the grocery industry will agree to broaden their assortments only if the manufacturer agrees to pay slotting fees for the new products. We investigate the role played by slotting fees in coordinating the assortment decisions in a supply chain. To do so, we study a single-retailer, single-man...
• Supply Chain Strategies for Perishable Products: The Case of Fresh Produce AI翻译
  作者：Blackburn, Joseph; Scudder, Gary
  作者单位：Vanderbilt University
  摘要：This paper examines supply chain design strategies for a specific type of perishable product-fresh produce-using melons and sweet corn as examples. Melons and other types of produce reach their peak value at the time of harvest; product value deteriorates exponentially post-harvest until the product is cooled to dampen the deterioration. Using the product's marginal value of time (MVT), the rate at which the product loses value over time in the supply chain, we show that the appropriate model ...
• Acquisition Management Under Fluctuating Raw Material Prices AI翻译

  摘要：We study a continuous-review acquisition problem, in which the raw material price follows a discrete-state Markov process and demand is compound Poisson. We show that one optimal policy is of the order-up-to type. Under our mean reversion and time continuity conditions, we further show that the order-up-to levels are decreasing at the current price level. At the same time, our computational study verifies that both conditions are indispensable for the monotonicity result. The study also hints ...
