The Research Of Industrial Plants Reliability Evaluation System Based On Fussy Comprehensive Evaluation

Industrial plants will have more or less damage after they are used long-termproduction in harsh conditions. This damage makes structures’ function decline,which affect the use of the structure、 the operation of equipment, even worse cancause plant collapsed and caused serious property damage and casualties.Firstly, this paper introduces the background and significance of this research,comprehensively illustrates the study of structural reliability assessment andevaluation software; analyses the pros and cons of various reliability assessmenttheory and application; submits fuzzy comprehensive evaluation methods used inindustrial plants reliability evaluation system; briefly introductions fuzzycomprehensive evaluation theory and basic steps.Secondly, this paper establishs factors of industrial plants reliability evaluationbased on existing norms and standards; studies the factors’ standard、the selecting ofthe membership function and the weighting coefficient of distribution; establishs thebasic framework flow chart of the system. Then, this paper uses ASP technology,Macromedia Dreamweaver software to design and establish the reliability evaluationsystem. This system achieves the research of the basic structure information andquality status, preliminary and detailed evaluation of structure, dynamic features suchas display of the measured sensor location. This system enables users be knowned tothe plant health.Finally, a case of Pingdingshan Province’s plant’s data is used, the evaluationresult which is consistent to the expert’s judgment validated the feasibility andreliability of this program. This system has certain research and applicationsignificance.
