FUZZY DECISION-MAKING APPROACH IN GEOMETRIC PROGRAMMING FOR A SINGLE ITEM EOQ MODEL

Background and methods: Fuzzy decision-making approach is allowed in geometric programming for a single item EOQ model with dynamic ordering cost and demand-dependent unit cost. The setup cost varies with the quantity produced/purchased and the modification of objective function with storage area in the presence of imprecisely estimated parameters are investigated. It incorporates all concepts of a fuzzy arithmetic approach, the quantity ordered, and demand per unit compares both fuzzy geometric programming technique and other models for linear membership functions. Results and conclusions: Investigation of the properties of an optimal solution allows developing an algorithm whose validity is illustrated through an example problem and the results discussed. Sensitivity analysis of the optimal solution is also studied with respect to changes in different parameter values.
