Research on Quality Evaluation of Multi-State Data of Substation Equipment Based on Game Theory Combined Weighting-Comprehensive Evaluation

Based on the game theory combination weighting-comprehensive evaluation method, this paper proposes a new method for evaluating the quality of polymorphic data. By building a data quality evaluation system for five indicators of integrity, accuracy, uniqueness, consistency and timeliness, using decision experimental analysis method and best-worst method game theory combination weighting method to determine the weight of each indicator, and then using comprehensive evaluation method. The method determines the quality of polymorphic data, improves the existing evaluation method, and combines specific examples to verify the feasibility and effectiveness of the method.
