Problems solved by technology

[0003] In view of this, the embodiment of the present invention provides a comprehensive evaluation method and system for the optimal configuration of distribution network resources to solve the problem that the measurement of a single index in the prior art is difficult to reflect the main characteristics of the optimal allocation of resources. When evaluating the optimal allocation of resources, the credibility of the evaluation results is low. When a single index is cross-referenced and comprehensively evaluated for the optimal allocation of distribution network resources, the evaluation results are highly subjective, and the evaluation results also do not have a high degree of confidence. question of credibility
