摘　　要：针对不同领域评标专家关注的评价指标集有差异情形的政府采购评标问题,在给出软集、软集的∧积运算及其uni-int算子和决策函数相关定义的基础上,给出了一种基于软集理论的评标方法。在该方法中,通过对uni-int决策函数进行有效扩展,给出了综合不同评价指标集评价信息的投标商初筛准则,在此基础上,通过定义初筛通过的各投标商优先序来确定最终中标者。最后,通过一个算例说明了该方法的可行性和有效性。With respect to bidding evaluation problems on government procurement with different evaluation criteria sets addressed by bidding evaluation experts from different domain, based on the definition of soft set, A-product of raft set, uni-int operators and decision function, a method for bidding evaluation is proposed based on soft set theory. In the method, by effectively extending uni-int decision function between two soft sets to multiple soft sets, the rule of tenderer selection to integrate evaluation information of different evaluation criteria sets is given. And on that basis, priority order of selected tenderer is defined to determine winner. Finally, a numerical example is given to illustrate the feasibility and effectiveness of the method proposed.
