A Lean Green Implementation Evaluation Method Based on Fuzzy Analytic Net Process and Fuzzy Complex Proportional Assessment

Abstract

For the issue that the optimal selection of lean green implementation tools for performance effect, a method combining fuzzy analytic net process (FANP) with fuzzy complex proportional assessment (COPRAS) is proposed. Firstly, the main properties of the lean green performance and candidate tools are determined based on the production requirements and expert knowledge. Then, the fuzzy comparison matrix of each attribute is constructed according to the expert judgment represented by triangular fuzzy number, and the FANP method is used to obtain the importance weight of each attribute. After that, the fuzzy decision matrix between attributes with tools alternatives is constructed, and multiplying it with the attribute weight so as to obtain the weighted normalized decision matrix. Finally, the fuzzy COPRAS method is used to analyze the decision matrix to get the utility of each tools alternative. Based on the model and analysis, these results make us understand and be familiar with the most influential practice tools on performance benefits. These findings are expected to policy makers and industrial practitioners to focus on key elements of the success of the manufacturing business to facilitate both lean and green manufacturing implementation and assessment, and contribute to sustainable growth.
