Description:
Quick Response is a new supply chain management system designed to meet the changing requirements of an increasingly more competitive market in the apparel sector. The main objective of this study is to build a Systems Dynamics stimulation model of the portion of the textile and apparel pipeline including the retailing and wholesale processes to search for inventory decisions and policies that yield reduced costs/increased revenues in terms of the retailer. As seen in Fig. 1, the model not only includes the main components of supply chain, but also incorporates how product diversity may affect sales, There are two conflicting effects: first, as the product diversity of the store increases, the probability that customers' preferences will be matched increases towards 1.0 asymptotically. (See Fig. 2a). This graph not only makes sense, but can also be obtained by probabilistic analysis, using Binomial probabilities (Barlas & Aksogan 1995) The opposite effect of increasing diversity implies lower stocks of each product type ("Typesupply"). Thus as the ratio type supply/demand decreases, higher fractions of demand will be lost due to type stockouts. (As shown in Fig. 2b) Therefore, the conflicting effects of product diversity is potentially worth investigating dynamically.
