• Improving performance in cyclic production systems by using forced variable idle setup time AI翻译

  摘要：In the early 1990s, research began to show that the Japanese production theory, which espouses reduction of machine setup time as a sure way to improve production performance, may be limited. Specifically, it was found that reduction in mean setup times without any change in variance can, paradoxically, increase waiting time and work in process (WIP) in a cyclic production system. Setup time variance was demonstrated to play a central role because of the paradoxes it produced with the resultin...
• Load-based POLCA: An integrated material control system for multiproduct, multimachine job shops AI翻译

  摘要：This article proposes a supporting framework for the implementation of the material control system POLCA (paired-cell overlapping loops of cards with authorization). The POLCA system is particularly appropriate for environments that involve highly variable demand and large product variety, which force small batch (or even one-of-a-kind) production. We propose a load-based version of the POLCA control system (LB-POLCA), which determines the POLCA parameters (release authorizations, allowed work...
• Mass customization vs. mass production: Variety and price competition AI翻译

  摘要：We study competition between two multiproduct firms with distinct production technologies in a market where customers have heterogeneous preferences on a single taste attribute. The mass customizer (MC) has a perfectly flexible production technology and thus can offer any variety within a product space, represented by Hotelling's linear city. The mass producer (MP) has a more focused production technology and therefore offers a finite set of products in the same space. The MP can invest in mor...
• Integrating the promotional and service roles of retail inventories AI翻译

  摘要：In some retail contexts, higher inventories not only improve service levels, but also stimulate demand by serving as a promotional tool (e. g., by increasing product visibility). Motivated by a building-products retailer's practice of stocking large quantities of products to stimulate demand, we study inventory management and pricing policies when demand is uncertain but increases with stocking quantity. We first characterize the profit-maximization policy for a stochastic inventory model with...
• Dynamic inventory management with learning about the demand distribution and substitution probability AI翻译
  作者：Chen, Li; Plambeck, Erica L.
  作者单位：Stanford University
  摘要：A well-known result in the Bayesian inventory management literature is: If lost sales are not observed, the Bayesian optimal inventory level is larger than the myopic inventory level (one should stock more to learn about the demand distribution). This result has been proven in other studies under the assumption that inventory is perishable, so the myopic inventory level is equal to the Bayesian optimal inventory level with observed lost sales. We break that equivalence by considering nonperish...
• Retail inventory management when records are inaccurate AI翻译

  摘要：Inventory record inaccuracy is a significant problem for retailers using automated inventory management systems. In this paper, we consider an intelligent inventory management tool that accounts for record inaccuracy using a Bayesian belief of the physical inventory level. We assume that excess demands are lost and unobserved, in which case sales data reveal information about physical inventory levels. We show that a probability distribution on physical inventory levels is a sufficient summary...
• On the choice-based linear programming model for network revenue management AI翻译
  作者：Liu, Qian; van Ryzin, Garrett
  作者单位：Hong Kong University of Science & Technology; Columbia University
  摘要：G allego et al. [Gallego, G., G. Iyengar, R. Phillips, A. Dubey. 2004. Managing flexible products on a network. CORC Technical Report TR-2004-01, Department of Industrial Engineering and Operations Research, Columbia University, New York.] recently proposed a choice-based deterministic linear programming model (CDLP) for network revenue management (RM) that parallels the widely used deterministic linear programming (DLP) model. While they focused on analyzing flexible products-a situation in w...
• Further improvements on base-stock approximations for independent stochastic lead times with order crossover AI翻译
  作者：Robinson, Lawrence W.; Bradley, James R.
  作者单位：Cornell University; William & Mary
  摘要：When inventory replenishments can arrive in a different sequence than the one in which they were placed, it is important to use the shortfall distribution to set the base-stock level. Because the exact shortfall distribution is quite difficult to compute, heuristics are commonly used in its stead. Bradley and Robinson [Bradley, J. R., L. W. Robinson. 2005. Improved base-stock approximations for independent stochastic lead times with order crossover. Manufacturing Service Oper. Management 7 319...
• A mathematical model for evaluating cross-sales policies in telephone service centers AI翻译
  作者：Byers, Reynold E.; So, Kut C.
  作者单位：University of California System; University of California Irvine
  摘要：Cross-selling in telephone service centers is seen by industry as a useful means to generate profits from an existing customer base. Introducing cross-sales to a service center, however, needs to be properly managed as it could degrade customer service quality. Real-time customer and system information can be used to set the appropriate control policy for cross-sales to enhance profitability without causing undesirable service degradation for calling customers. The objective of this paper is t...
• A newsvendor's procurement problem when suppliers are unreliable AI翻译

  摘要：We consider the problem of a newsvendor that is served by multiple suppliers, where any given supplier is defined to be either perfectly reliable or unreliable. By perfectly reliable we mean a supplier that delivers an amount identically equal to the amount desired, as is the case in the most basic variant of the newsvendor problem. By unreliable, we mean a supplier that with some probability delivers an amount strictly less than the amount desired. Our results indicate the following effects o...
