摘要
用粗糙集中组合属性重要度确定单属性重要度的理论,给出了供应链最佳合作伙伴选择的新方法,改进了文献[1]的粗糙集评价方法,新方法计算的指标权重结果避免了文献[1]中计算的指标权重为0的情况出现,同时新算法计算的各指标重要度之和比原算法各指标重要度之和大,计算精度更高,评价结果更符合实际。
The theory that combinational attribute significance degree to determine the single attribute significance based on rough set has triggered a new method of Selection of Supply Chains Cooperators and has improved the method in paper [ 1 ]. The new method has solved the problem in paper [ 11 that the weight of some index is zero. Meanwhile, the sum of significance degree of each index with new algorithm for computing is larger than algorithm of paper [ 1], with higher accuracy in computing, and more objective evaluation results.
