A Comprehensive Study of Fuzzy Economic Order Quantity Model with Ramp Type Demand for Perishable Products

Abstract

In this study, explore a fuzzy inventory model for declining products, with a ramp shape demand feature and no shortage. The rate of depreciation is proportional to the unit production expense, while demand is inversely proportional. The aim of this study is to apply Trapezoidal fuzzy numbers and sign distance for defuzzification, and achieve an optimal total cost for the given scenario under uncertainty. The model is illustrated and validated numerically, and a comparative study in both cases crisp and fuzzy approach is obtained and provide the best solution approach for the model.
