双射软集合理论是软集合理论的一个分支,它用来解决不确定问题的一种新型数学工具。在研究已有文献的基础上,对双射软集合的理论及应用进行拓展研究,首先简单回顾双射软集合的定义、运算以及应用等相关理论,其次在应用部分重点给出双射软集合分明矩阵的参数约简思想,最后通过决策分割之间的依赖关系确定决策权重,同时在应用方面进行算例分析,结果显示合理。
Bifacial soft set theory, a branch of soft set theory, is a new mathematical tool used to solve uncertain problems. On the basis of studying the existing literature, this dissertation studies the theory and application of birefringence soft set. Firstly, the author briefly reviews the definition, operation and application of birefringence soft set. Secondly, we focus on the application of birefringence soft set The parameter reduction idea of the distinct matrix is used to determine the weight of the decision-making through the dependence relationship between the decision-making partitions. At the same time, the case study is applied in the application and the result is reasonable.
