Modeling method for product comprehensive design process and its realization

To solve the problems of poor effective integration and combination of Reliability, Maintainability and Supportability (RMS) design with performance design during present product digital development process, a distributed comprehensive design process model with flexibility was defined and implemented. Aiming at characteristics existing in comprehensive product design process such as intentional iteration, strong coupling, work item selectivity, coexistence of determinate and non-determinate process, concepts of gray-box node, black-box node and flexible process modeling elements were introduced. A complete scheme by stages and levels for distributed definition of process model was presented so that RMS design could be effectively and reasonably integrated into the complex product development. Supported by Product Lifecycle Management (PLM) technology and typical digital design environment platform, a process model for typical board level electronics integrated design was exemplified and applied into practice. The application and implementation results showed that the process model had enough flexibility to support effective integrated design.
