Comprehensive evaluation method and terminal for input and output benefits of power grid unit

The invention discloses a comprehensive evaluation method and terminal for the input-output benefits of a power grid unit, and aims to establish unit input-output benefit evaluation indexes conforming to the power grid industry, establish a unit input-output benefit evaluation model, automatically calculate the comprehensive evaluation score of the input-output benefits of the power grid unit, and improve the evaluation efficiency. Wherein the unit input and output benefit evaluation model comprises an index processing module, a weight determination module, an index score calculation module and a comprehensive score calculation module, the weight of each index is determined by adopting a Delphi method, and each benefit result is evaluated through the benefit evaluation model. A power grid unit can be assisted in checking input-output benefits and positioning weak links of input-output; and then a specific comprehensive evaluation score can be accurately calculated, and comprehensive evaluation of the input an
