The best alternative would be the one that is nearest to the positive ideal solution (the solution that maximizes the benefit criteria and minimizes the cost criteria) and farthest away from the negative ideal solution. In the traditional TOPSIS method, the weights of the criteria are known precisely and crisp values are used in the evaluation procedure. However the major drawback is that the uncertainty and imprecision related with representing decision makers observations to crisp values. Therefore, the fuzzy TOPSIS method is proposed. Fuzzy set theory allows the decision maker to incorporate unquantifiable information, inplete information and nonobtainable information and partially ignorant facts into the decision model .The fuzzy set theory is intended to deal with the abstraction of the main viable effect from an array of information that is expressed in vague and imprecise terms. Linguistic variable is very useful in dealing with circumstances, which are too multifaceted or not well defined to be reasonably described in typical quantitative terms. The linguistic variables that are applied in the model can be expressed in triangular fuzzy Numbers for each criterion. 4. Numerical Illustration Proposed model is applied to a real problem in industry. A printing industry located in the Southern part of India is selected. The industry wanted a systematic way to implement the reverse logistics operations. Reverse Logistics brings significant improvements in the manufacturing process and the correct decisions made brings the industry petitive advantage. Therefore selecting the most important operating channels is of great importance for the industry. To collect the used papers and magazines from the customers, the industry may choose MO, TPO, JO. A hybrid methodology bing AHP and TOPSIS under fuzzy environment is utilized for the selection. Schematic diagram of the proposed model is presented in figure a team prising two engineers and one manager was formed. The data required for selection are obtained through direct questions. 5. Conclusions Since financial and operational attributes are involved, the implementation of reverse logistics may be an unsafe task for the industry. However growing environmental concerns have forced the industries to opt for reverse logistics. The question is by which channel the industries will be able to collect the returned product. A methodology based on AHP and TOPSIS under fuzzy environment is proposed for the selection of RL operating channels. The problem has been described as a multicriteria decision making method under uncertainty, prompting the need for the method to handle imprecise judgments from decision makers. Future research includes incorporating a two phase methodology bining AHP and Fuzzy VIKOR and carrying out sensitivity analysis to confirm the robustness.
