Analisis Efektivitas Penyelesaian Masalah Transportasi Fuzzy dengan Menggunakan Metode Improved Exponential Approach

Abstract

Transportation is an activity that affects the smooth wheels of the economy. The core problem of transportation is to minimize distribution costs. Parameters that affect distribution costs in the form of demand, supply and transportation costs are sometimes not fixed, so it needs to be stated in a fuzzy set to solve it. In 2021, the cost of distributing rice at Perum Bulog Sub Divre Medan is very high accompanied by uncertain demand and supply so that the parameters of demand and supply are expressed in fuzzy numbers. In this study, the improved exponential approach method was used to find optimal solutions in rice distribution by taking into account three parameters, namely demand, supply and distribution costs. The improved exponential approach method is a method that is able to solve balanced and unbalanced transportation problems directly. However, to solve problems in fuzzy form, this method is combined with fuzzy integer transportation to find integer values that can represent fuzzy sets. The calculation results show that the cost of distributing rice in 2021 using the improved exponential approach method has decreased by IDR 41,155,480 from the actual distribution cost of IDR 729,593,658. From these results, it can be concluded that the improved exponential approach method is able to optimally solve the fuzzy transportation problem in 2021 at the Perum Bulog Sub. Divre Medan
