Abstract Particle Swarm Optimization（PSO）is a newly appeared method for Swarm Intelligence optimization. PSO was used by author for optimization design of reliability of mechanical parts and assemblies，and establishment of its mathematical model. In addition，inter-comparison between PSO and generic algorithm（GA）is taken. The results of experiments show that the optimal solution can be quickly and effectively reached with PSO，thus PSO is proven to be an effective method for optimization design of reliability of mechanical parts and assemblies.
