Title Lead Time Demand Modeling in Continuous Review Supply Chain Models.
Publication Date Apr 2013
Media Count 20p
Personal Author A. W. Johnson B. R. Cobb
Abstract This paper introduces a mixture distribution approach to modeling the probability density function for lead time demand (LTD) in problems where a continuous review inventory system is implemented. The method differs from the typical 'moment-matching' approach by focusing on building up an accurate, closed-form approximation to the LTD distribution from its components by using mixtures of truncated exponential (MTE) functions. First, construction of the LTD is illustrated and the approach is compared to two other possible LTDs. This distribution is then utilized to determine optimal order policies in cases in which a buyer makes its decisions alone, and later in a situation in which members of a two-level supply chain coordinate their actions.
