Fuzzy Inventory Model With Weibull Distributed Deterioration Along Variable Demand and Time Varying Holding Cost
Abstract
The present paper investigates a fuzzy continuous inventory model for deteriorating items with variable demand. The deteriorating rate follows weibull distribution. In Real world situation it has been observed that the cycle time of every supply chain system is uncertain hence, it has described with triangular fuzzy parameters. The Yager's formula and signed distance method is applied to de-fuzzify the cost function. A numerical illustration has been proposed to validate the model. The sensitivity analysis has been carried out to explore the effect of minor changes in parameters with the optimal solution associated to different parameters.
