针对影响因素重要性分析中存在的问题,基于区间数可能度矩阵提出了一种分析影响因素重要性的新方法。根据影响热油管道进站温度因素参数取值波动的事实,使用区间数描述因素参数的取值。利用相对优势度比较目标参数变化区间的大小,建立判断因素重要性的区间可能度矩阵,进而得到重要性排序向量,实现影响因素重要性排序。热油管道进站温度影响因素重要性分析结果表明,影响因素参数均值不同、变动幅度不同或者单独改变某因素参数,都会改变影响因素的重要性,说明该方法具有通用性,可以有效地进行影响因素的重要性分析。
Aiming at the problems existing in the importance analysis of influencing factors, a new method to analyze the importance of influencing factors is proposed based on the interval number likelihood matrix. According to the fact that the parameter value of the temperature factor of hot oil pipeline entering the station fluctuates, the interval number is used to describe the value of the factor parameter. The relative dominance is used to compare the size of the change range of the target parameters to establish the interval probability matrix of the importance of the judgment factors, and then the importance ranking vectors are obtained to rank the importance of the influencing factors. The analysis of the importance of influencing factors for the temperature of the hot oil pipeline entering the station shows that the importance of the influencing factors can be changed by different means of the influencing factors, different amplitudes of change or single changes of the parameters of a certain factor, indicating that the method is universal and can be effectively influenced Importance Analysis of Factors.
