Decision Support System for Selecting the Best E-Wallet using TOPSIS Method

A decision support system (DSS) is a system that can quickly solve problems that arise in ranking and determine the highest to lowest score for a selection. In this article, is one of the case studies that can be done using a decision support system and represents the problem ms faced when looking for the best e-wallet, the selection requires the use of a manual evaluation process that takes time to obtain results . Therefore, a decision support system was created that can support the evaluation process. This decision support system uses the TOPSIS and ROC methods used for testing which aims to determine the accuracy of the value obtained by the system, sensitivity tests are carried out on the weight value of the criteria, and modified experiments are carried out with the aim of knowing how many criteria can be added, each criterion has its own weight value to determine the ranking of alternatives. Based on the ranking, the results obtained from the calculation of the TOPSIS and ROC methods, the best is LinkAja (A5) with a value of 0.7518.
