为提高复杂产品研制流程建模与优化的效率,提出一种基于设计结构矩阵和系统建模语言(SysML)的建模与优化方法.首先利用SysML对复杂产品进行需求分析获得系统初步设计方案,并利用设计结构矩阵对产品研制流程进行层次化分解并优化,从而减少设计活动的迭代;然后通过SysML对产品研制流程进行图形化建模表达与分析,以保证模型的一致性和可重用性,提高建模准确率和效率.以发动机为例,验证了该方法的有效性.%For the purpose of improving the efficiency of modeling and optimization of complex product devel-opment process, a method based on design structure matrix and SysML is presented. Firstly, this method under-takes requirements analysis for complex product through SysML and obtains the preliminary system design scheme. The product development process is hierarchically decomposed and optimized with the design structure matrix method in order to reduce the iterative design activities. Secondly, the development process is graphically modeled and represented by SysML, which contributes to the guaranteeing of consistent and reusable process models and improves the accuracy and efficiency of process modeling. Finally, an example of engine is demon-strated to verify the effectiveness of the proposed method.
