Proposed Methodology Decision makers find the problem of assessing the variety of alternatives and then selecting the best one using a set of criteria. Multiple criteria decision making methods (MCDM) are discrete with a restricted number of alternatives. A decision matrix in MCDM consists of three main parts a) Alternatives b) Criteria c) Weights of Relative importance. In this paper, a hybrid methodology based on Analytical Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) under fuzzy environment is presented. The weights of criteria are calculated by applying the AHP method. The Fuzzy TOPSIS method is applied to get the final ranking results. Although AHP is a decisionmaking methodology in itself. its ability to get accurate ratio scale measurements and bine them across multiple criteria has led to AHP applications in conjunction with many other decisions support tool and methodologies. Uncertainty and imprecision is handled with linguistic values parameterized by the triangular fuzzy number. Analytic Hierarchy Process AHP method is developed by Prof. Thomas L. Saty. AHP divides a plex problem into a hierarchy of interrelated decision elements. AHP can deal with objective as well as nontangible subjective attributes. The procedure of AHP is as follows . Model the problem as a hierarchy Develop a hierarchical structure with a goal at the top level, the criteria at the second level and alternatives at the third level. Alternatives are affected by uncertain events and are connected to all criteria. Construct a pairwise parison matrix A set of parison matrix with respect to an element of immediately higher level is constructed. The pairwise parisons capture a decision makers perception of which element dominates the other. Test the Consistency by calculating the Eigen Vectors The relative normalized weight of each attribute is determined by calculating the geometric mean of the row and then normalizing the geometric means of rows in parison matrix. A consistency ratio of or less is considered as acceptable for matrices M a consistency ratio is more than the acceptable value, inconsistency occurs, and the judgments are untrustworthy, the evaluation process needs to be improved. Consistency ratio helps to ensure decision maker reliability in determining the priorities for the criteria. TOPSIS Method Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was first established by Hwang amp。 然而越來越多的環(huán)境上的問題，迫使企業(yè)去選擇逆向物流。 4 模型應(yīng)用 所提出的模型被應(yīng)用于工業(yè)上的一個(gè)問題。最好的選擇將是最接近積極的理想解決方案（該方案最大化了收益標(biāo)準(zhǔn)，最小化了成本標(biāo)準(zhǔn)）以及遠(yuǎn) 離了消極的理想解決方案。層次分析法的步驟如下： 問題的模型層次化 在最高水平目標(biāo)的前提下制定一個(gè)分層次的結(jié)構(gòu)，第二層級(jí)是標(biāo)準(zhǔn)，第三層級(jí)是可選擇的方案，可選擇方案受到不確定活動(dòng)的影響，而且與所有的標(biāo)準(zhǔn)相關(guān)聯(lián)。在本章節(jié)中，基于層次分析法（ AHP）和技術(shù)模糊環(huán)境下逼近理想解排序法（ TOPSIS）相結(jié)合的混合方法將會(huì)呈現(xiàn)。第二部分將提出問題，第三部分將給出解決的方法概述，第四部分將給出一則案例作為論證，第五部分進(jìn)行總結(jié)，得到研究成果?？梢酝ㄟ^第
