Operation and maintenance efficiency evaluation method and system based on operation and maintenance quality management database

The invention discloses an operation and maintenance efficiency evaluation method and system based on an operation and maintenance quality management database, and the method comprises the steps: firstly obtaining operation and maintenance management data, generating corresponding operation and maintenance efficiency data, dividing the operation and maintenance efficiency data into operation and maintenance efficiency data of different levels, and then constructing a utility coefficient analysis optimization model of the operation and maintenance efficiency data, analyzing the utility coefficient of the current target efficiency value and evaluating the influence coefficient of the current target efficiency value increased along with time, generating evaluation data after evaluation, and finally responding to the evaluation data to match an operation and maintenance optimization scheme and outputting a result. According to the method, the operation and maintenance efficiency evaluation model of the operation
