Abstract—To improve the accuracy and efficiency of task decomposition of R&D (Research and Development) projects, a new decomposition method based on product structure tree was proposed. The relevance between product structure tree and work breakdown structure (WBS) was analyzed through their natural quality and association relations. The mapping rules between product components and project tasks were defined. Mathematical models about the mapping from components and parts to tasks and combining tasks were established. Based on the above mechanism and models, the automatic mapping transformation from product components to project tasks was achieved. A prototype system was developed based on the task decomposition method, and the system had been applied in R&D projects of a diesel engine factory, which verified its effectiveness and feasibility.

Index Terms—product structure tree, work breakdown structure, mapping transformation
