摘　　要：介绍应用于复杂系统的协同优化方法的基本思想和计算框架,并将可靠性理论引入协同优化方法中,优化时加入可靠性约束。在协同优化的系统级优化中,引入松弛变量,将一致性等式约束转化为不等式约束,使该算法易于收敛。该方法实现45吨铰接式自卸车轮边减速器的并行可靠性优化设计,将优化结果应用于实际工程。Basic ideas and computing frameworks of collaborative optimization（CO） which is applied to complex system design are introduced. Reliability theory is introduced into CO, and reliability restraint is applied to optimization design. Within the optimization of systematic level of collaborative optimization, the slack variable is introduced to let the restraint of consistency equality be transformed to the restraint of non-equality, and makes easily the algorithm convergent. This method realized the parallel reliability based optimization design of the wheel hub reducer of articulated dump truck（ADT）, and the results of the optimization were applied to the practical project.
