粒子群算法在化工设备可靠性分析中的应用

Application of Particle Swarm Optimization in Structural Reliability Analysis

基于可靠度指标的几何含义,分析了粒子群算法的原理、模型和算法实现过程。通过算例用MATLAB语言编程进行计算,并与一次二阶矩法和蒙特卡罗法得出的结果进行了比较,证明了粒子群算法在化工设备可靠性分析中的有效性和可行性。

Based on the geometric implication of reliability index, this paper analyzes the principle, model and the algorithm realization of Particle Swarm Optimization（PSO）, in which through a ease calculation, MATLAB - the programming language is applied in the calculation and also it is compared with the results of the first - order second - moment methed（FSOM） and genetic algofithm（GA）, proving that the method is effective and feasible in the reliability analyse of machinery equipment.
