Inventory Flow in Supply Chain with Deteriorating Items for Customers in Queue: Computation of Profit Optimization in Fuzzy Environment

摘要

The present paper makes a fresh attempt to discuss the inventory flow in supply chain with deteriorating items for customers in queue and its profit optimization in fuzzy environment by using computational approach. The system has been fuzzified by using Zadeh’s extension principle and triangular and defuzzified by centroid method. Consequently, by applying optimization technique, a system of non-linear equation has been developed and it has been solved by using fast converging Newton Raphson’s (N-R) method. A sensitivity analysis has been also carried out to gain deeper insight into the model under consideration.
