摘要
对于工程系统的优化设计，本文讨论了各分系统（或单元）最优化与总系统最优化的关系．提出了各分系统（或单元）单独进行优化设计后所得总系统能够实现最优的条件，并给出了数学证明；讨论了一般情况下分系统（或单元）单独优化后所得总系统并不能达到最优化的原因，指出对一般工程大系统必须进行全局协调优化才能真正收到优化的效果．
For optimum design of large scale engineering systems,the relationship of subsystems(or elements)optimization and global optimizationof systems is discussed,the conditions on which independent optimzationsof subsystems(or elements)are equal to global optimization of system arepresented and proved, the reason why independent timization of subsystems(or elements)are not equal to global optimization for general engineeringsystems is geven.It is ponied that for general engineering large scale systems,global coordinating optimization is necessary.
