Abstract: To extend the decoupling ability of traditional workflow engine, and to eliminate the data flow decoupling in multidisciplinary design process, a multi-objective collaborative data flow decoupling strategy was proposed, and a data flow decoupling ware was developed. In order to improve reusability of integrated design software and disciplinary model, from the perspective of collaborative design method framework, the modeling process was modified. By remaining unchanged of various sub-disciplinary models, design results of various disciplines were analyzed by using clustering method. Functions to judge multi-objective satisfaction rate were added in order to acquire reasonable design results.The application of small solid rocket design proved that the extended workflow engine could realize the process decoupling control of multidisciplinary design and obtain the global feasible solutions of design problem, thus the management disadvantages of traditional workflow method on multidisciplinary coupling design process were remedied.
