Abstract: In the Multidisciplinary Design Optimization（MDO） integration system, both the design process and optimization solution algorithm are based on the workflow. Workflow validity verification is important for improving the work efficiency and improving the user experience of the system. The most validity verification method is proposed for the workflow in office automation and enterprise information management system, a few for MDO workflow. Based on study in the previous works, a algorithm, named concentration-loop, for the analysis and verification of MDO workflow with loop structure character, based on graph theory, is proposed. With the launch platform digital design system design and implementation, the feasibility of concentration-loop algorithm is proved.

Key words: multidisciplinary design optimization, workflow verification, graph, workflow

摘要： 在多学科设计优化集成系统中，设计过程和优化求解算法均通过可视化工作流实现，工作流有效性验证对提高设计效率和提高系统的用户体验具有重要意义。当前验证方法主要针对办公自动和企业管理系统中的工作流验证问题，多学科设计优化集成系统中的工作流验证问题研究较少。在分析前期工作验证技术的基础上，针对以循环结构为特征的优化环，提出一种基于图论方法的，名为浓缩环（concentration-loop）的验证算法。结合发射平台数字化设计系统的设计与实现，对该算法进行了验证。
