工程大系统优化设计的设计条件最优分配

Optimal Distribution of Design Conditions for Large Scale Engineering System Optimum Design

对诸如航天器、发电厂、汽车、土木结构等实体工程系统进行优化设计就是在满足工程性能指标,设计可用资源等条件限制下按一定评价标准寻求最优设计方案的过程。值得指出的是:目前的工程优化设计理论几乎都是针对具体单元、孤立结构的;系统工程的优化理论又几乎全是针对已建成系统的运行,控制和管理的。对于如何利用计算机等现代数值分析计算手段自动高效地设计一个工程系统,使其得到总体上的全局性的协调一致的优化,据我们所知,成熟的理论为数甚少,尚处于探索阶段。

In the paper, the conception of global coordinating optimum design for large scale engineering systems, based on the advanced engineering soft design theory, the dominant ideas (optimum distribution of design conditions), mathematical model and solution techniques of above-mentioned optimum design problem are presented, reasonableness and effictiveness of the theory and methodologies are proved by an example.
