摘要:T his research studies the impact of improved forecasts on the members of a two-stage supply chain. The supplier builds capacity based on original forecast information, and the manufacturer places its order after observing improved ( but imperfect) demand information. We study three types of wholesale price purchasing arrangements: ( 1) when the wholesale price is determined to be exogenous to the supply chain; ( 2) when the supplier sets the wholesale price; and ( 3) when the manufacturer set...

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...

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...

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...

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...

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...

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...

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...

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...
