为了对软集合各参数进行约简的同时更大程度的保留集合性质,使约简方法更广泛地运用于决策分析与决策系统,文中在软集合理论的数据挖掘方法基础上,从决策系统各因素的重要程度出发,提出了一种新的约简方法,得到简化的参数集.文中首先分析了以往软集合的决策规则,然后定义了参数的影响因子,并提出了更能反映元素决策等级的加权选择价值,从而构造了一种新的不可区分关系和决策优先级.最后将该约简算法运用到购房决策系统中,为决策者提供有价值的信息,并得到了可行的约简结果.

In order to reserve the properties of soft set while reducing the parameters,a new approach of parameter reduction is proposed by using the data mining based on soft set theory,according to the importance degree of each factor in decision making system,which is more widely used in decision analysis systems and obtains a reduction parameter set. Firstly,the former decision rule is analyzed. Next,the impact factor of parameter is defined as well as the weighted choice value that denotes the decision making level for each element. Then, a new indiscernibility relation and decision making priority are presented. Finally,the algorithm for reduction is applied in a house pur-chase system to show some valuable information and give a feasible result.
