Abstract
This paper presents a mathematical framework to obtain a production model for perishable items with a learning effect in production cost. The study considers different demand rates at different. This model is along with the concept of two warehouses, where one is its own warehouse (OW) and the other is a rented warehouse (RW). The demand rate for RW is strictly increasing function of time which is exponential, and selling price of inventory in own warehouse in such a way that the producer gets the benefit and can build the according to his profit, also production rate is dependent on demand. Hethe re concept of shortage is also considered. In this model, we analyzed the changes in the total cost by taking item price and production time as a decision variable. The optimal solution has presented with the use of the centroid method with q- fuzzy number. A numericaexamplesle and sensitivity analyses of some parameters are provided to examine the impact on the optimal total cost of the system.
