A Fuzzy Non Linear Programming Approach of An Inventory Model For Time Dependent Deteriorating Items With Three Rates Of Production

摘要

An inventory model with three different rates of production and quadratic demand rate is considered. The shortages are allowed and deterioration rate is time dependent. The objective is to determine the optimal total cost and the optimal time schedule of the plan for the proposed model. To illustrate the results of this model, numerical example is presented.
