| 摘 要： | 介绍了双射软集合的基本概念,并提出了基于双射软集合决策系统的参数约减算法(BSSR),同时还考虑了论域中元素带权重的算法(W-BSSR),并与粗糙集方法进行比较,结果表明BSSR与粗糙集方法的结果相同.而W-BSSR则能够处理论域中元素权重不同的参数约减问题.

| Abstract: | This paper introduced the concept of bijective soft set and proposed the parameter reduction based on bijective soft set decision system (BSSR). Moreover, this paper considers the situation that element in universe with weight and proposed weighted bijective soft set based parameter reduction as well, and compares BSSR with rough set based reduction. The results show that BSSR can obtain the same result as rough set based reduction and W-BSSR can solve problem that element with different weight in universe. |
