In today's competitive business world, it is extremely important for decision makers to have access to decision support tools in order to make quick, right and accurate decisions. One of these decision making areas is courier service selection. Courier service selection is a multi - criteria decision making problem that deals with the optimization of conflicting criteria on which decision maker's knowledge is usually vague and imprecise. In this project, fuzzy TOP­SIS method is proposed to select appropriate alternatives. To gather initial data, a committee of three decision makers were asked by a questionnaire. In this questionnaire, the decision-makers use the linguistic weighting variables to assess the importance of the criteria. They use the linguistic rating variables to evaluate the rating of alternatives with respect to each criterion. Using fuzzy-TOPSIS approaches all criterion in hierarchy were ranked. Our findings demon­strated that using fuzzy-TOPSIS method price, timeliness, quality of information, services and warranty are the five first important criteria in order to rank each alternatives of courier ser­vices. Finally, a numerical example is provided to demonstrate the computational efficiency of the proposed fuzzy TOPSIS method.
