Utilizing a cyclic queue system, this paper investigates the effect of variance on a multi-item production facility …. Reduction in setup time, for example, is usually presumed to reduce inventory. We demonstrate that inventory can blow up if … examined, such as its relationship to KAIZEN and Just-In-Time production practices, and especially its property of impairing …

This paper investigates a single-vendor single-buyer integrated production-inventory model with stochastic demand and … imperfect production process. It is assumed that there is an inspection activity on the part of the buyer with a fixed screening … rate greater than the demand rate. The vendor invests money in order to improve the production process quality and reduce …

In this paper we introduce a new class of OR games: economic lot-sizing (ELS) games. There are a number of retailers that have a known demand for a fixed number of periods. To satisfy demand the retailers order products at the same manufacturer. By placing joint orders instead of individual...
