A Supply Chain Inventory Model for Deteriorating Items with Variable Lead Time and Varying Demand under Shortages


Vipin Kumar Tyagi, Ruchi Goel, Manindar Singh and Sunil Kumar
Abstract

In this model we have developed a supply chain inventory model for the decaying items where the deterioration rate is assumed to be constant and the demand rate is considered as price 1dependent. Shortages are allowed and partially backlogged. To make the study realistic we have considered an uncertain lead time which is assumed to be a decision variable. Mathematical formulation has been done to find out the optimal replenishment policies. Theoretical results have been verified through a numerical example and the effect of variation is examined via sensitivity analysis.
