【Abstract】 In this paper,some classes of optimal design model for complex structure are given by using some simple examples,they can be divided into four classes: independent type, network type,hierarchical type and mixed type,for each type,its general optimization model is given,its corresponding decomposition-coordination strategy is also put forword.更多还原
