Problems solved by technology
[0003] At present, there are two problems in the research on the selection of transmission line routing schemes. One is that the calculation of index weights is seriously affected by subjectivity, the evaluation scale is too single and rigid, and the uncertainty of human cognition is not fully considered; the other is that the calculation theory cannot Fully reflect the relationship between the various selection factors that affect the program, and cannot clearly reflect the pros and cons of each program

The invention relates to the technical field of power transmission line path scheme evaluation, and provides a power transmission line path scheme optimization method based on a cloud matter element. An index system influencing scheme optimization is constructed in combination with the influence on each society and each aspect of nature in a power transmission line construction process and after construction, a triangular fuzzy analytic hierarchy process based on a COWA operator is used to determine the weight value of each hierarchy index, the evaluation grade result of the scheme is determined according to the comprehensive grade correlation degree by using the cloud matter element theory, and then the power transmission line path scheme is optimized more scientifically, comprehensively and reasonably. Therefore, on the basis of comprehensively considering uncertainty existing in judgment of importance of each influence factor by experts and incompleteness and fuzziness of available information, a cloud matter-element model for power transmission line path scheme optimization is established.
