英文摘要： The management and control of multi-source design changes is a great challenge during the concurrent design processes of complex products. Therefore this research will focus on the new solutions of change propagation prediction, propagation path plan and change cost estimation for the multi-source design changes. First, the design feature of the complex product will be modeled by using semantic technology to operate the changes consistently between various design processes and ensure the data coherent. Then the design change analysis network will be built based on the design feature semantic model. The propagation mechanism of the design changes will be studied quantitatively at the design feature granularity in the change analysis network. Subsequently, the propagation paths of multi-source design changes will be optimized based on the aforementioned change propagation mechanism and some heuristic optimization algorithms. Through the multi-agent technology, the design changes will be self-adapted to be absorbed and counteracted along the propagation paths. Consequently the impact imposed by the design changes will be controlled within a minimum area and the chances of change conflicts will be decreased. Finally, the evaluation principle about the optimization propagation paths of design changes will be established, which will be employed to estimate the variations in cost, quality and efficiency due to the series of design changes. This principle will be a theoretical reference for making design change decisions. The innovative research work is carried out by taking the design features into account for planning the propagation path of the multi-source design changes, which will be an effective method for managing the changes of complex products during the concurrent design processes.
