Firstly, the relation between the suppliers and the customers is analyzed. Seondly, the evaluation index system and fuzzy quantitative methods are provided. Thirdly, the CSD evaluation system including eight indexes and three ranks based on one-against-one mode of SVM is built, last simulation experint is presented to illustrate the theoretical results.展开更多
应用Logistic回归模型确定权重的模糊综合评判法分析边坡稳定性,是主观评判和客观数据相结合的分析方法,其评判结果更让人容易接受,具有良好的适用性.选取重度、内聚力、内摩擦角、边坡角、孔隙水压力比5个因素作为评价因子,边坡状态稳...应用Logistic回归模型确定权重的模糊综合评判法分析边坡稳定性,是主观评判和客观数据相结合的分析方法,其评判结果更让人容易接受,具有良好的适用性.选取重度、内聚力、内摩擦角、边坡角、孔隙水压力比5个因素作为评价因子,边坡状态稳定、较稳定、欠稳定、不稳定4个等级作为评价等级,建立评价等级和评价因子之间对应的关系,确定隶属度函数,建立综合评判模型;同时采用逻辑回归模型,应用42个边坡实例,运用SPSS(Statistical Product and Service Solutions)软件求解回归系数,采用回归系数来确定评判权重;将综合评判模型和确定的权重应用于龙南县东江乡足洞试验矿某边坡实例中,评判结果与实际相符合.展开更多
