Outline
The evaluation of the purchasability of mining equipment is a critical issue in the decision-making process for equipment selection in mining enterprises. To address the limitations of traditional evaluation methods, such as the simplicity and lack of systematicity, a comprehensive evaluation method based on the GRA-AHP-Cloud Model was proposed. Firstly, an evaluation index system was constructed, encompassing four dimensions: production platform, adaptability, functionality, and cost. Secondly, the analytic hierarchy process (AHP) was utilized to determine the weights of each evaluation index, and the grey relational analysis (GRA) was employed to calculate the comprehensive correlation degree between each index of the equipment and the ideal value. Finally, a mathematical model for evaluating equipment purchasability was established through the cloud model, enabling the fuzzy quantitative expression of evaluation results. The method is validated through a case study of mining trolley selection in a mine, demonstrating its effectiveness in assessing the comprehensive performance of equipment.
