Modeling and Analysis of Weaving-preparation Systems with Respect to Small-lot Manufacturing Part I: Problem Definition

Abstract

The implementation of quick-response manufacturing strategies in the textile industry has led to the realization of smaller lot sizes for woven-fabric producers. In this first part of a two-part work, the effects of this shift are explored, and an approach for producing within a short-run environment is presented. A definition of small lot sizes is also developed for weaving preparation that holds for a wide range of product mixes. Basic models of the weaving preparation processes as multistage flow shops are given for the purpose of design and analysis. Finally, a framework for the design of appropriate small-lot weaving-preparation systems is defined. In Part II of this work, the analysis component of this framework will he used to characterize the performance of weaving-preparation systems with respect to small-lot manufacturing.
