Defuzzification을 고려한 TOPSIS 다기준 의사결정 방법

Abstract

Companies in materials, assembling parts, services, and vendor evaluation and selection for purchase problem degree of uncertainty, decision makers, including criteria to consider the properties of the multi-criteria decision-making is an issue. This study in a group decision-making process, as measured by linguistic variables by fuzzy data based on the weight of decisions after interpreting defuzzification TOPSIS method to evaluate the study was about decision-making. As a result of this study to determine the evaluator`s ambiguous representation of linguistic variable, then by the number of fuzzy trapezoidal fuzzy set theory was applied to representing. Defuzzification weights were analyzed by considering decision problems, defuzzification when considering previous research among a more efficient decision-making alternatives were possible. Be able to choose a more viable alternative to the proposed methodology.Companies in materials, assembling parts, services, and vendor evaluation and selection for purchase problem degree of uncertainty, decision makers, including criteria to consider the properties of the multi-criteria decision-making is an issue.
