摘　　要：给出一次二阶矩法、蒙特卡洛法和粒子群算法求解可靠度的MATLAB简便程序。应用划分网格法与避免了维数灾的粗格子法求解几何可靠度;通过并行粗格子法求解可靠度时,将约束优化转化为无约束优化应用了外惩罚函数法。MATLAB, a simple and convenient method incorporating first-order second-moment, Monte-Carlo Method and PSO, is developed to calculate structure reliability. It is also proposed to calculate geometric reliability with divided mesh method and coarse divided mesh method that can avoid dimensional disaster. When using parallel coarse divided mesh method to calculate geometric reliability, the exterior penalty function is introduced to transform constrained optimization into unconstrained optimization.
