In optimizing design, there are some contradictions amongst every object of the system;the main object of system and the object of subsystem also have some contraventions as well as the object of every subsystem. Because of those problems, the optimum allocation of the main system cannot be achieved by optimizing every single subsystem;That is to say, the connection of simple optimization is unequal to the complex optimization.

工程系统优化设计中，不但多个目标间存在矛盾、而且系统总目标与子系统目标间及各子系统目标间也存在矛盾，所以各子系统单独优化后所得结果一般说来并不意味着工程系统本身的优化，正像各构件独立优化后凑成的结构并不一定最优一样。
