A Fuzzy Inventory Model for Deteriorating Items with Linear Price Dependent Demand in a Supply Chain

Abstract

In this paper we have developed a supply chain production inventory model for deteriorating items under fuzzy environment. Demand is taken as linear price dependent. In reality it is seen that we cannot define all parameters precisely due to imprecision or uncertainty in the environment. So we have defined the inventory parameters, such as set up cost, holding cost and deteriorating cost as triangular fuzzy numbers. The signed distance method and graded mean integration method have been used for defuzzification. To illustrate the proposed model a numerical example and sensitivity analysis with respect to different associated parameter has been presented.
