In allusion to the impossibility of conducting both a specific product's reliability modeling and performance modeling at the same time as well as the fact that the reliability design of a product being out of line with performance design, this study defines a modeling method of function model based on SysML, which allows the systems engineers to build system function model using IBD to depict the relationships of system static function and generate reliability block diagram. An algorithm based on system function matrix is also proposed. This work enables an automatic reliability block diagram analysis during the system performance design phase. Such a method promotes the effectiveness and reliability of products as well as the consistency that a reliability design may be involved with performance design.
