Abstract
Implementing cleaner production (CP) is effective to resolve the contradiction between economic growth and environmental crisis. To avoid destroying the ecological environment in the exploitation process of mineral resources, CP has been developed in many gold mines to achieve the goal of sustainable development. Thus, this paper aims to propose a favorable approach to assess CP for gold mines. First, according to the specific characteristics of gold mines, an evaluation criteria system of CP is established. Meanwhile, considering the diversity of evaluation information, crisp numbers and probabilistic linguistic term sets (PLTSs) are adopted to indicate the quantitative and qualitative information, respectively. Subsequently, a modified experts grading method based on PLTSs is proposed to calculate the sub-criteria weights’ values. Following this, an extended Tomada de Decisão Interativa Multicritério (TODIM) method with hybrid evaluation values is presented to obtain the ranking order. Finally, the hybrid multi-criteria decision making (MCDM) approach is applied to a case of assessing CP for gold mines to demonstrate its feasibility. Furthermore, the robustness and advantages of this approach are justified by sensitivity and comparison analyses. The results show that the proposed approach is feasible to solve such kinds of evaluation problems with hybrid decision making information and can provide some managerial suggestions for government and enterprises.
Highlights
Gold, as an important strategic mineral, is a special currency for reserves and investment, and an essential material for jewelry, electronics, communications, and other industries [1]
(3) The traditional Tomada de Decisão Interativa Multicritério (TODIM) method is extended with crisp numbers and probabilistic linguistic term sets (PLTSs), which can efficiently deal with practical hybrid multi-criteria decision making (MCDM) problems, including quantitative and qualitative evaluation information
This paper focused on proposing a hybrid MCDM approach to evaluate cleaner production (CP) for gold mines
Summary
As an important strategic mineral, is a special currency for reserves and investment, and an essential material for jewelry, electronics, communications, and other industries [1]. Considering the diversity of criteria, an extended TODIM method based on crisp numbers and PLTSs can be proposed to assess the CP for gold mines. (3) A hybrid MCDM approach on the basis of an extended TODIM method is proposed to assess CP for gold mines, which can obtain stable and reliable evaluation results. These evaluation results can provide some managerial implications for government and enterprises.
