Abstract: The complexity of modern product design requires high level design process management which can support multi disciplinary concurrent design. To provide high level problem\|oriented process management services, the concept and method of design process management are put forward based on a problem solving model. Design process is regarded as a process of problem definition, planning, and solving. Discipline knowledge is captured through process description language, and design problems are broken down and solved based on process grammar. The theory and method presented can reflect the nature of design process, and effectively support the designer with high level multi disciplinary process management services, thus shorten the design cycle.
