Abstract: This paper is based on parallel genetic algorithm.The reliability optimization problem in terms of software system is converted into a kind of nonlinear optimation problem with a large number of constraints. Furthermore,it greatly improves the search performance on using the island model and migration policy.The imitate results manifest that the algorithm can effectively improve the computing speed and the resolution quality.
