SUSHIL KUMAR*

Abstract


In the present paper we considered an inventory model for deteriorating items with stock dependent selling rate and fuzzy type deterioration. Shortages are allowed and completely backlogged. The backlogging rate of unsatisfied demand is assumed to be a decreasing exponential function of waiting time. The purpose of our study is to defuzzify the total profit function by signed distance method and comparing the results of this method with the crisp model. Further a numerical example is also given to demonstrate the developed model and to show the sensitivity analysis of the effect of change of parameters.
