摘要
在人机系统可靠性评价中,评价因素众多且具有不同属性.为使评价结果尽可能多地体现这些属性,且避免多指标权重难以确切分配这一弊端,文章在灰色关联分析法的基础上,将可靠性标准的各级别视为区间的概念,同时对分辨系数ρ的取值进行了探讨以避免随意性;然后,按隶属度最大原则确定人机系统可靠性评价等级.实例分析表明,该方法层次分明,简便实用,对人机系统可靠性评价具有较好的适用性.
In man-machine system reliability assessment, there are lots of factors with different attributes. For the purpose of reflecting the attributes in the assessment and avoiding the trouble of distributing weight to every index, which is difficult generally, and according to the principle of relational grade of grey systems theory, the reliability standard is taken as a zone and the coefficient is discussed to avoid the random; and then, according to the principle of maximum relevancy, the degree of the man-machine system reliability is ascertained. At last, a practical example is given and it shows the method has a preferable applicability in the reliability assessment of man-machine system.
