复杂工程系统综合设计优化环境

建立了系统整合、流程统一、参数优化、协同设计的综合设计优化环境.通过 分析复杂工程系统的特点,建立了具有高可扩展性的多层体系架构.阐述了组成该环境的4 个关键模块:项目组织与管理模块,保证项目进度和质量;以设计结构矩阵为表达形式、以 工作流参考模型为运行机制的过程建模与执行模块,提供跨部门的任务流转;基于组件技术 ,实现人员、数据和工具在网络上紧密集成的设计任务单元模块,为系统设计提供简洁一致 的任务模型;以产品数据管理(PDM,Product Data Management)为信息基础结构的产品数 据模型,提供单一数据源.最后给出了技术实现和运行机制.该环境的原型系统已成功地经 过了气动、结构、控制和总体设计等领域的设计与优化技术测试试验. 

Complex engineering system synthesis design optimization framework

Synthesis design optimization environment was built for system integration,process unification,parameter optimization and collaborative design.The high extensible and multi-tiered architecture of this environment was built on the analysis of characteristic of complex engineering system.Four key modules were discussed: project organization and management module guarantees project schedule and quality;process modeling and running module applies design task structure for representing design processes,workflow reference model for running,and provides the ability of task transition across organization;design task unit based on component technology integrates people,data and tool over network,and provides a coherent task model for system design;product data model uses PDM(product data management) as information infrastructure,and provides a single representation of product.The implementation of the environment and running mechanism were presented.The prototype of this environment has been successfully tested by the design and optimization experimentations in fields of pneumatics,structure,control and system design.
