In this case the researchers used a questionnaire / questionnaire in evaluating the ideal salon. In this case a decision support system is needed to rank the ideal salon recommendations so that a decision support system is a solution offered to resolve the problem.
Many branches of computer science can solve complex problems. Among them is Artificial Intelligence [1]- [10]. Decision support systems are part of artificial intelligence that can be used to avoid the assessment of subjectivity that is produced [11]. Objectivity assessment is needed so that the decision support system can help consumers in choosing the ideal salon with consumer needs. Research ers used the SMART (Simple Multi Attribute Rating Technique) method. This is because the SMART method is able to solve problems with multi criteria. The following are some of the previous studies that used the SMART method to solve problems. One of them is done [11] with the title selection of cattle for beef cattle breeders using the SMART method. The results of the study explained that the SMART method can be applied to the selection of cattle types with the result that the Lemosin cattle (A1) type is the first recommendation with a final score of 1 and Bali cattle (A3) as the second recommendation with a final value of 0.702543.
