Fuzzy Inventory Model for Slow and Fast Growing Items with Deterioration Constraints in a Single Period

In this paper, a fuzzy inventory model with random demand rate for two items with deteriorateconstraints have been proposed. The Lower-Upper (L-U) bud with rhombus fuzzy number is defined and its properties are given. The proposed model is formulated in fuzzy environment.ie., the parameters involved in this model are represented by L-Ubud with rhombus fuzzy number. The agreement index of L-Ubud with rhombus fuzzy number is explained and using this technique the total cost is defuzzified. Maximum inventory level per period is determined. A numerical example is given to illustrate both the proposed crisp model and fuzzy model.
