【摘要】Combining with international emerging theory of soft set,this paper proposes a synthetically evaluating method for business competitive capacity based on soft set.The proposed approach overcomes the deficiency of traditional methods,deal with the problems which mixed all kinds of uncertainty.It has no use for constructing an analytic mathematical model and defining the notion of the exact solution of this model,it entirely depends on drive of data to evaluate and analyze.The algorithm is very convenient and easily applicable in practice.The validity and feasibility of the proposed approach is verified with a case.
