Power distribution network operation assessment method and system

The invention discloses a power distribution network operation assessment method. The method comprises the steps of counting student scores, building a knowledge point score index set C, and building a sample set S according to the student scores; establishing a student total score index set B; based on the sample set S, the student total score index set B and the knowledge point score index set C, calculating an information gain rate of the knowledge point score index set C to the sample set S; and constructing a score decision-making tree according to the information gain ratio of the knowledge point score index set C to the sample set S. According to the invention, the direct relationship between each knowledge point and the total score can be clearly seen through constructing the score decision-making tree, and a teacher can conveniently make targeted training in the future. 本发明公开了一种配电网作业考核方法，包括统计学生成绩，构建知识点成绩指标集C，根据学员成绩建立样本集S；建立学生总成绩指标集B；基于样本集S、学生总成绩指标集B以及知识点成绩指标集C计算知识点成绩指标集C对于样本集S的信息增益率；根据知识点成绩指标集C对于样本集S
