A Case Study Based Simulation of Green Supplier Selection Using Fmcdm and Order Allocation through Molp

The purpose of this paper is to select Green Supplier using Integrated Fuzzy Multi Criteria Decision Making (FMCDM) and allocates order through Multi Objective Linear Programming (MOLP) approach along with and Supplier Selection Software development. To select supplier this paper investigates various qualitative and quantitative criteria. For that, this paper integrates Fuzzy Analytic Hierarchy Process (FAHP), Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS), and Fuzzy MOLP to solve the problem of supplier selection and order allocation. At first the authors used Fuzzy AHP to calculate the relative weights of supplier selection criteria; then, the authors used Fuzzy TOPSIS for ranking of suppliers according to the selected criteria. Finally, the weights of the criteria and ranks of suppliers were incorporated into the MOLP model to determine the optimal order quantity from each supplier while being subjected to some resource constraints. Research provides the weight and rank of the suppliers and also optimum order quantity among them according to their rank.
