To address the issues of suboptimal utilization and excessive resource waste in the grid, this study proposes a model for evaluating the operational efficiency of equipment in the operation and inspection system. The proposed model employs a fuzzy comprehensive assessment approach. Initially, the relevant factors influencing equipment utilization in the operation and inspection system are identified and organized to establish an index system. Redundancy between the indexes is reduced through correlation analysis, resulting in a multilevel index system for evaluating equipment utilization. The weights are determined including different methods: the Analytic Hierarchy Process (AHP) for subjective weights and the Grey Relation Analysis (GRA) method for objective weights. The combined weighting method is applied to obtain the comprehensive weight coefficients of the system. Fuzzy comprehensive evaluation theory is then introduced to quantify the utilization rate of equipment in grid operation and maintenance systems, this approach ensures a scientific and rigorous assessment process. Finally, the case study results demonstrate that the model can effectively reflect the utilization level of equipment, with assessment outcomes aligning with real-world scenarios, providing valuable insights for grid equipment planning and construction. By analyzing the data of Shanghai Power Grid, the case results prove that the evaluation system and method can effectively reflect the utilization level of equipment, with assessment outcomes aligning with real-world scenarios, providing valuable insights for grid equipment planning and construction.
