系统工程过程中的综合设计方法

针对复杂产品,将设计作为在一定约束条件下的求解过程,基于系统工程过程的分析,提出了以"需求-功能-结构"为解空间,以"分析-综合-评价"为执行机制的系统综合设计方法,确立了系统综合设计的基本流程,并依据系统综合设计方法,建立了由集成产品与过程模型、工具管理体系构成的综合设计平台,从而为实施系统综合设计方法提供了一个统一的、集成的环境,帮助工程人员以系统的观点组织和协调产品设计活动,保证整个产品设计过程中的所有活动都是围绕系统整体开展,并以一种统一化手段完整地确定出系统的所有技术、功能要求和物理结构,保证最终系统在给定环境下的行为表现符合用户最初的期望. 

System synthesis design method in system engineering process

Based on the design process acted as a solution-finding process under certain constraints, and on analysis of the system engineering process, for a complex product, a system synthetic design method with ‘request-function-structure’ solution space and ‘analysis-synthesis-evaluation’ execution mechanism was presented, a basic process for system synthetic design was determined for complex product, and a synthetic design platform composed of integrated product and process models and a tool management architecture was established according to the system synthetic design method, thereby providing a uniform integrated platform for engineers, implementing the system synthetic design method, helping the engineers to organizing and coordinating the product design action with a whole system view, ensuring that all of the action in the whole product design process was performed based on the whole system, fully determining all technologies, function requests and physical structures by a uniform mean, and ensuring that the performance of the final system in a given environment can satisfy the original expectation of users.
