摘要：In this paper, the multi-level grey system theory method is used to evaluate the economics of the circulating water system. Firstly, the influencing factors of each part are divided into different levels, and the weights of each factor are determined by using the analytic hierarchy process. Secondly, the influencing factors are divided into five commentary categories based on the Grey system theory. The whitening weight function of the grey class is established, and then the whitening value is calculated. Finally, the weight of the circulating water system belongs to each grey class, and the economic performance of the cooling water system is reasonably and objectively evaluated. Through the calculation and description of a specific example of the cooling water system, the economics of the whole cooling water system and various links are obtained. The economic evaluation results obtained by the analysis are in line with objective laws and provide a new way for the economic evaluation of the cooling water system.
