基于偏联系数的得分函数构造方法

A construction method for score functionbased on partial connection number

分析了集对分析中已有偏联系数得分函数的不足和缺陷,并构造了新的偏联系数得分函数.通过分析新得分函数,有效刻画了偏联系数中异向偏于正向和负向的趋势变化中的不确定主观因素,解决了偏联系数中得分函数评价结果与客观判断不一致的问题,在此基础上讨论了新的得分函数的构造准则及性质.最后,通过实例分析比较了新得分函数的有效性和可行性.

Aim to the existing problems of partial connection number score function in set pair analysis,a new partial connection number score function is constructed.Through the analysis of new score function,the uncertain subjective factors in the trend changes of the same direction and the opposite direction in the partial connection number are effectively described with different bias relations,and the problem of inconsistency between the evaluation results of the score function in the deviation coefficient and the objective judgment is solved.On this basis,the relevant construction criteria and meanings of the new score function are discussed.Finally,an example is given to compare the effectiveness and feasibility of the method.
