A Fuzzy Programming Approach To Inventory Control Problem
In this paper an inventory control problem has been considered in fuzzy environment. In inventory, holding
costs, set-up costs etc. may be flexible with vagueness in their values. Fuzzy set theory has been used to convert the fuzzy
model into a crisp one. Compensatory operator and weighted compensatory operator have been used to aggregate the fuzzy
membership functions corresponding to fuzzy sets for fuzzy objectives & constraints. This aggregation gives the overall
achievement function and the model takes the form of a Geometric Programming (GP) Problem. GP algorithm has been used
to solve the problem.
