Inventory Model in a Fuzzy Environment with Exponential Membership Cost Functions

In this paper, an EOQ Model has been analyzed in a fuzzy environment. Its objective goal, holding cost, shortage cost, set-up cost and storage area are all represented by means of three different combinations of linear, parabolic and exponential membership functions. Fuzzy non-linear programming (FNLP) method with Lagrange multipliers is applied. This method has been illustrated by means of numerical examples. The variations of the results with those of the crisp model have been pointed out. Sensitivity analysis of the model has also been carried out.
