Abstract: To solve the problem of long period,high production cost and unstable quality in gas tightness detecting equipments,the design processes of detecting principle and detecting equipment were analyzed,and the adaptable design method based on classified base was described.A factor-considered cluster method which could determine the weight vector of factors by Analytic Hierarchy Process (AHP) was put forward.Through setting the consistency degree of tested parts on each factor,the weighted algorithm for similarity was obtained,and the cluster norm was given.The process of iterative cluster algorithm was explained,and the software based on the method was developed.Cases showed that the proposed method was effective in planning the classified base,which could be used to support the adaptable product case design.
