Problems solved by technology

[0003] However, among the investment decision-making evaluation indicators of the original distribution network production project, there are both positive investment decision-making evaluation indicators and negative impact investment decision-making evaluation indicators; if the evaluation indicators are not scientifically and reasonably classified and standardized, It will affect the accuracy of the decision-making method; thus, it is impossible to complete the optimization decision-making of the distribution network production project, and it is impossible to ensure the maximum investment benefit of the technical transformation project
