APPLICATION OF THE TOPSIS METHOD IN DETERMINING THE LOCATION OF A NEW GRET LAUNDRY BRANCH

Abstract

In opening a new branch, one important factor that needs to be considered is the selection of a new branch location. Because the location of a new branch determines the future journey of a business. If the selection of the location of the business is carried out carefully, then the business that is run will run well and vice versa. In determining the location of a new branch will be very difficult if done manually. Therefore we need a system that can help solve these problems, SPK is a computer-based system that will ultimately help in deciding where to find a good new branch location. In using SPK, a method is needed. The method used in this study is the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. TOPSIS is a method in SPK which means it is a ranking method that uses the longest and shortest distances to measure its ranking. Based on this research, it was finally obtained 0.8589 which was achieved by alternative B7 on behalf of Jalan Sisingamangaraja, as the location of the new Gret laundry branch.
