A Novel Hybrid MCDM Model for Location Selection of Collection Centers in Closed Loop Supply Chain based on Sustainability Dimension

Location selection decisions involved many factors that may be conflicting in nature. Considering Sustainability factors in location selection problem, this paper propose a hybrid framework based on two novel MCDM methods which can be applied for selecting the optimal location that satisfies the decision maker. In this regard, first by the survey of the related literature, main criteria of location selection of collection centers in closed loop supply chain based on sustainability dimension were identified. In the second step by means of judgmental sampling, a committee of 15 experts of glass industry was formed and their idea about the importance of criteria was extracted through questionnaire. Then Linear Goal Programming was applied for calculating the relative importance or the criteria weights. In the third step for demonstrating the applicability of the model five collection centers, were ranked by Similarity-Based Approach and GTMA methods based on the sustainability dimension. The input information for this phase was obtained by experts of Hamdean Glass Company which were selected by judgmental sampling.
