摘　　要：通过分析战域保障网络的构造和特点,提出了基于级联失效的战域保障网络节点容量优化模型,进而研究了3种优化策略对级联失效抗毁性的影响:度升序优化策略、度降序优化策略、随机优化策略。结果表明按度降序策略优化约50%的节点可以有效提高战域保障网络级联失效抗毁性。A node capacity optimization model for campaign logistics networks based on cascading failure is proposed by analyzing its construction and features. Based on the optimization model, the effects of three optimization strategies on network invulnerability are investigated： degree-descend optimization strategy, degree-ascend optimization strategy and random optimization strategy. It is shown that the degree-descend optimization strategy with 50% node selection proportion can improve the network invulnerability effectively.
