Optimal multiple delivery schedule for demand in logistic model

Traditional analysis for determining inventory levels assumes constant or n ormally distributed demand over the period of analysis, which is not suitab le for products of short life-cycles as commonly found in fashion-related p roducts. This paper utilizes a logistic growth function and a logistic subs titution function to model the growth, saturation, and decline of such prod ucts with varying yet dependent demands. A heuristic that finds the minimum cost single-order multiple deliveries schedule for the logistic demand is developed to facilitate the use of the logistic model. (C) 2001 Elsevier Sc ience B.V.
