Abstract

Here a single item inventory model for deteriorating items without shortages under fuzzy sense is formulated and solved. Fuzziness is introduced by allowing cost components, demand rate, deterioration rate and the production rate. In fuzzy environment, demand, holding cost, set-up cost, deterioration cost, production rate, deterioration rate etc. are assumed to be pentagonal fuzzy numbers. The purpose of this model is to minimize the total cost function in fuzzy scenario. Signed distance method is employed to defuzzify the total cost function per unit time in fuzzy approach. We provide a numerical example to illustrate the theoretical result obtain by the above defuzzification method. Sensitivity analysis of parameters is also carried to detect the effect of change of their values.
