| 摘 要： | 提出了一种结合D-S证据理论和模糊理论的安全评估方法.从实际应用的角度出发,将证据空间中的事件视为模糊子集,通过引入模糊子集,更好地描述了专家意见(或知识),给出了证据函数的表示.最后,结合某船舶系统,给出了安全评估的具体实现过程.结果表明,该方法可靠、有效,具有一定的实际应用价值.

| Abstract: | A method of security assessment combining D-S theory of evidence and fuzzy theory is put forward in this paper. According to the applications, the events of evidence space are considered as fuzzy subsets. When the fuzzy subsets are introduced, the opinion (or knowledge) of experts can be described better, and the evidence function is also given. Finally, the practical assessment process is given through an illustrative example of ship system. The results show that the method is effective and reliable with practical value. |
