摘　　要：可靠性分配是系统可靠性设计的重要任务之一,其结果直接影响系统的设计方案。为了能快速获得在一定费用约束条件下的可靠性优化分配结果,减少分配过程中的主观因素,建立了可靠性预计值的可靠性分配模型,并设计了新的编码方式和新的变异率调整模型,使改进后的遗传算法能用于求解复杂系统的可靠性分配问题。最后给出导弹武器可靠性分配的计算实例和结果分析。Reliability allocation is an important part of reliability design because its result influences system design directly. In this paper, reliability allocation model with the constraints of cost is established based on reliability prediction to get optimal reliability allocation results of complicated network system. Furthermore, new coding and new self-changeable rate is designed to improve tradition genetic algorithms for seeking optimal solution to this model. In the end, we use the model and acquired ideal results.
