Abstract
The construction of Green Mine has become an essential policy for the management of mineral resources in China. This study aims to propose a favorable approach to assess the performance of Green Mine. The evaluation criteria are recognized based on the specific characteristics of Green Mine. Considering that some of these criteria could not be mutually compensated, a novel multi-criteria decision making (MCDM) method is presented. It integrates the TODIM (an acronym in Portuguese of interactive and multi-criteria decision-making) method with the elimination and choice translating reality (ELECTRE) method in a picture fuzzy environment. In most existent methods, the evaluation information of Green Mine is described by real numbers. However, in this study, picture fuzzy numbers (PFNs) are first used to express such information to effectively indicate the uncertainty and fuzziness in the evaluation process. Another innovation is that the entropy weights model and the best-worst method (BWM) are combined to determine the comprehensive criteria weights. The practicability and advantages of the proposed method are verified by a case study and a comparative analysis with other methods. In addition, the influences of some parameters are discussed using sensitivity analysis to judge the flexibility and robustness of the proposed method. The results show that the proposed approach is feasible for solving the non-compensatory problems of evaluation criteria and can provide references for the performance evaluation and management of Green Mine.
Highlights
With the expanding global population and the rapid economic growth, the demand for mineral resources has greatly increased [1], [2]
This study focused on proposing a combined multi-criteria decision making (MCDM) method with picture fuzzy information to evaluate the performance of Green Mine
The largest contribution of the proposed work is that it integrated the advantages of picture fuzzy numbers (PFNs), TODIM and ELECTRE to well address Green Mine performance evaluation problem
Summary
With the expanding global population and the rapid economic growth, the demand for mineral resources has greatly increased [1], [2]. For coping with limitation (3), a modified approach based on the TODIM method can be proposed to solve the non-compensatory problems of evaluation criteria. The traditional TODIM method has an obvious defect in that it is not able to deal with these evaluation issues since the criteria cannot be mutually compensated In this case, this study considers the combination of the TODIM with another powerful means, the elimination and choice translating reality (ELECTRE) method [28]. Based on the motivations mentioned above, the aim of this study is to propose a combined TODIM-ELECTRE decision making method with picture fuzzy information for assessing the performance of Green Mine. A combined TODIM-ELECTRE method is proposed for picture fuzzy circumstances It complements the advantages of both PFNs and classical decision making methods.
