Through the investigation research on practical damaged element , considering the effect of corrosion , high temperature , wet environment , damage ( crack ) on structural durability , bearing capacity . this paper established the reliability analysis method of large - scale industrial factory , and applied the fuzzy mathematics to establish the factor set and weight coefficient set on the basis of expert experience . an analyzed method for fuzzy evaluation of structural element and bent frame structure system reliability is put forward 通过对实际结构破损构件的调查，考虑腐蚀，高温，环境潮湿，破损(裂缝)等因素对结构耐久性、承载力的影响，论文建立了大型工业厂房可靠度的计算方法，利用专家经验和模糊数学方法建立了模糊评价的因素集和权重集，对钢筋砼结构构件和厂房排架结构体系进行了模糊评价。
By way of multi - factor fuzzy integration decision - making , the algorithms of the ship tracks correlation from radar and ais ( automatic identification system ) were researched , and the mathematic models were setup including the fuzzy factor sets , evaluation sets , single - factor fuzzy judgment matrix , multi - factor fuzzy integration decision - making rule , and the quality of the correlation and disengagement 摘要采用多因素模糊综合决策方法，研究了雷达与ais （船舶自动识别系统）目标航迹关联算法.建立了该算法的模糊因素集、评价集、单因素模糊评判矩阵、多因素模糊综合决策准则、以及航迹关联与脱离质量等数学模型。
