Abstract: 3F integrated technology is a reliability analysis technology consisted of two modules,i.e.,FMECA and FTA,by methods based on a comprehensive analysis of potential failure prediction and improvement of function modules and the FRACAS prototype known fault closed-loop control function module.The research ideas that 3F integrated technology be applied to the whole process of new product development was described.The process model and the implementation of the operation flow of 3F integrated technology in the new product development were focused,and presentation of its case-specific process of implementation was given.Finally,for the 3F integrated technology and its application in new product development,pending development study were proposed.
