Establishment and application of G1-CRITIC-MEEM model for evaluation of utilization efficiency of power grid assets

Accurate evaluation of the utilization efficiency of power grid assets not only helps power grid enterprises to grasp the current status of the assets used now and strengthen the assets management but also helps to improve the quality and efficiency of power grid operation and promote the sustainable development of enterprises. In this paper, an evaluation index list of power grid asset efficiency is established by literature research method and expert interview method. Then, the questionnaire survey method and factor analysis method are used to screen, refine and classify the indicators to form the evaluation index system of the utilization efficiency of power grid assets. The index system includes two first-level indicators, four second-level indicators, and eight third-level indicators, which comprehensively reflect the utilization efficiency of fixed assets and current assets of power grid companies, and it is systematic, concise, and operable. Combining the G1 method, CRITIC method, and matter-element extension method, the G1-CRITIC-MEEM model for evaluating the utilization efficiency of power grid assets is established, which can reflect the status and overall level of all indicators that affect the use efficiency of power grid assets comprehensively. The established model is applied to an example, and the evaluation results obtained are consistent with the actual situation, which verifies the scientific and effectiveness of the model. This provides a new path for the evaluation of the asset utilization efficiency of power grid enterprises.
