摘要
有效管理虚拟设计中仿真优化决策的不确定性问题,能确保产品开发的成功几率。本文首先分析了虚拟设计中仿真模型不确定性的来源,研究总结了不确定性建模的基本方法;将虚拟产品开发过程中的决策方式分为非合作决策、顺序决策和合作决策三种;引入稳健设计哲理和工程随机变量优化设计方法,分别提出了对应的不确定管理策略;最后,通过复合材料结构设计进行了应用说明。
The purpose of uncertainty management of simulation optimization decision in virtual design is to ensure the product development success probability. Firstly, the potential uncertainty sources of simulation model in virtual design are concluded, and modeling methods for uncertainty are also concluded. The decision manners in the virtual product development process are classified into three cases, i.e., non-cooperative decision, sequential decision and cooperative decision. Simulation uncertainty mitigated strategies for different cases mentioned above are presented by means of robust design and engineering stochastic variable optimization methods. Finally, a composite material structure design problem is given as an example.
