厂房可靠性的模糊综合评判

研究厂房可靠性模糊综合评判法的基本原理与(操作)方法.结合厂房的结构特点,将模糊评判应用到厂房鉴定中.通过确定影响结构可靠性模糊变量的隶属度,形成损伤或破坏因素的评价矩阵,采用三级模糊推理逻辑运算,判定厂房结构的可靠性.通过一个工程实例,将模糊综合评判法与现行规范评判法进行比较.结果表明利用模糊综合评判法所得到的计算结果信息量大、直观性强,具有更高的可信度.

Fuzzy comprehensive evaluation of reliability of workshop buildings

The basic principle and implement procedure of fuzzy comprehensive evaluation of workshop buildings were investigated in order to use it for appraisal of workshop buildings with their special structural feature.The reliability of the building structure was to be evaluated by means of defining the membership of fuzzy variables,which would have influence on the reliability of the building,to form an evaluation matrix,and as well as employing a logic operational approach of three-step fuzzy inference.The evaluation method presented was compared to the standard one available through an engineering example.Its result showed that the information obtained by using the evaluation method presented were large,straightforward,and of even more trusty.
