Reliability Modeling and Analysis of Assembly Process of Products Based on GGSPN
摘要
Abstract
Aiming at the assembly step of products,the paper put forward a modeling method based on GGSPN focusing on the assembly reliability of products.First of all,the GGSPN model dur-ing the assembly process of products was set up before which the assembly relation analysis among va-rious assembly steps was done.Secondly,the simplication of the GGSPN model was realized based on the basic stochastic Petri net model and the equivalenced-performance equation.Thirdly,according to the uncertain lack-of-information problems of failure information during the assembly process,the pa-per employed grey numbers into the generalized stochastic Petri net model to optimize the vicissitude stimulating rate.Moreover,the stable-state probability represented by grey numbers and the whiteni-zation were worked out directing at the set-up reliability model of the assembly process of products. After the reliability analysis during the assembly process,the improved measures of reliability control were carried out.In the end,the feasibility of the mentioned method was proved by the assembly process of a gear oil pump as example.关键词
