Abstract

The invention relates to a credibility evaluation method for a 3D simulation training system of a high-voltage cable constructing operation based on a variable weight theory. According to the credibility evaluation method, starting from evaluation index selection of the credibility of the 3D simulation training system of the high-voltage cable constructing operation, trapezium cloud is adopted to describe uncertainties existing in a credibility evaluation process of the simulation training system, conversion of a qualitative concept and quantitative calculation is realized, and calculation of evaluation index degree of membership is realized; a constant weight of each evaluation index is calculated by adopting an improved fuzzy hierarchy analytical method; specific to the problem that comprehensive evaluation cannot make sensitive response to severe distortion of very few indexes in the credibility evaluation for the 3D simulation training system of the high-voltage cable constructing operation, a punishment type state variable weight function is configured according to the self attribute of the credibility evaluation for the 3D simulation training system of the high-voltage cable constructing operation, so that the weight of each index is reallocated along with the changes of a credibility evaluation result; and a fuzzy weighting operator is adopted to calculate the credibility evaluation result of the simulation training system.
