Materials & methods: Fuzzy PROMETHEE and fuzzyTOPSIS approaches were used.Fuzzy PROMETHEE utilizes a pair-wise comparison ofalternatives under the fuzzy environment while fuzzy TOPSISutilizesgeometric distance from the positive ideal solutionunder the fuzzy environment for the evaluation of the effectiveness of the alternatives.The techniques selected for evaluation are applied behavioral analysis, cognitive behavioral therapy, speech therapy and pharmacological therapy such as Risperidone and Aripiprazole. Criteria used in this study include efficacy, cost and side effects, and their weights are assigned based on specific patient conditions.
