Abstract: Based on traditional process planning technology, the general method and process of Reliability, Maintainability, Testability, Supportability, Safety (RMTSS) synthetical design process planning and reconstruction were put forward. Effect of RMTSS design on product design process was comprehensively analyzed. Considering characteristics of interaction among tasks in synthetical design, an information dependency determining method with multiindex was proposed. In view of the disadvantages of the existing tearing algorithms which resulted in abnormal sorting of coupled tasks，a fuzzy clustering algorithm was developed to divide the couple tasks sets and reorganize coupled tasks together with tearing algorithm and aggregation algorithm. Finally, synthetical design between performance, reliability and testability of printed circuit board was demonstrated.
