An integrated production model in fuzzy environment under inflation

Abstract

In this research article, an integrated system with variable production is developed in fuzzy environment. The demand rate is regarded as an increasing function of time. In developing the proposed model, it is assumed that the manufacturer takes the raw materials in multiple batches from the supplier, process them to produce finished products and deliver to the buyer in multiple shipments. The effect of inflation and time value of money is also taken into consideration. All the cost parameters are considered as triangular fuzzy numbers and signed distance method is used for defuzzification. The model is illustrated with numerical example and sensitivity analysis with respect to the system parameters is also executed.
