摘要  基于区间数层次分析法研究大型钢铁企业关键备件——轧辊供应商评价.轧辊供应商评价需综合考虑轧辊的性能、价格、质量、供应商的交货能力、服务水平等属性,属于多属性决策问题,而钢铁生产过程的连续性、轧辊供应商分散性、质量严格性等特点,使轧辊供应商评价更为复杂.区间数能柔性地表达决策者的偏好,适合不确定背景下的决策.以区间数层次分析法为框架研究轧辊供应商评价问题,然而,区间数判断矩阵的权重求解方法并不成熟.Mikhailov最近提出一种新方法,简单实用,不足之处是隶属度函数设置有误.文章对此加以修正.最后,将修正方法应用到国内某大型钢铁企业轧辊供应商评价之中. The problem of the key spare-roll vendor selection for the large-scale iron-steel enterprise is studied based on the interval numbers analytic hierarchy process. Roll venll vendor selection should be formulated as a multiple criteria decision-making problem since the purchaser must consider the performance, price, quality, delivery and service, etc synthetically. In addition, the roll vendor selection problem becomes more complex because of the continuity of iron-steel production procedure, the dispersion of the vendors, and the strict requirements to quality. The interval numbers can express the decision-maker's preference more flexible and it is adapt to the decision-making problem under the uncertainty. Therefore, the interval numbers analytic hierarchy process is adopted to solve the roll vendor selection. However, the weight approaches deriving from the interval numbers comparison matrix aren't perfect. Mikhailv had put forward a new weight approach recently. It was simple and practicable, but its membership function was faultiness. To solve the problem, the correction of that approach is made. Then it is adopted as the roll vendor selection for a large-scale iron-steel enterprise in China.
