Pseudo excitation method ( pem ) is used, thus one random process excitation can be transformed into a deterministic transient excitation, so the joint - random problem is turned into a single - random problem accurately, it can be solved easily by means of perturbation method and sequence orthogonal decomposition theory respectively. the probabilistic approach is used to transform stochastic optimization into deterministic optimization, therefore the optimization can be achieved through multiple objective decision making theory
以虛擬激勵法為基礎，將隨機過程激勵轉化為確定性動力激勵，從而將復合隨機問題精確地轉化為僅結構參數具有隨機性的問題，分別利用攝動理論和次序正交分解理論推導了確定性動力激勵下隨機結構響應特徵，採用概率方法將隨機優化問題轉化為確定性優化問題，從而可以通過多目標決策理論進行結構優化設計。
