The operation and maintenance phase of established large gymnasiums lacks a holistic evaluation system and a dynamic evaluation method, which makes it difficult to reflect the overall performance and status of management. To solve the above problems, this study establishes an evaluation system for operation and maintenance performance and status indicators and proposes a dynamic evaluation method that integrates spatial and temporal dimensions. First, operation and maintenance performance and status indicators are identified and weighted using the fuzzy Borda method. Furthermore, the operation and maintenance performance and status of a single building is evaluated in the time dimension by variable-weighted composite method, and the comparison of operation and maintenance performance and status of gymnasiums in different spatial dimensions is realized by considering the time weights. The case validation evaluates the dynamics of five large gymnasiums in Beijing in both temporal and spatial dimensions.
