基于微粒群算法的区间模型非概率可靠性指标的计算
Calculation of non-probabilistic reliability index of interval model based on PSO
摘要
Abstract
The uncertain parameters in engineering is considered as interval variables and the non‐probabi‐listic reliability index of interval model based on particle swarm optimization is studied .Based on the conclusions that the non‐probabilistic reliability index exists only in the line w hich through the vertex and the origin in the space extended by the standard interval variables and function ,establish the optimi‐zation model based on PSO and improve the objective function to make it more conducive to calculate . Through a series of numerical examples and comparison with previous methods ,the method is proved to be simple and accurate ,and it has a certain feasibility .关键词
