摘要

针对线性编队无人机集群多阶段任务可靠性建模问题,首先基于加速时间失效模型构建集群中单架次无人机的多阶段任务可靠性模型;其次将单架次无人机可靠性的量化结果引入线性连续n中取k系统的可靠性模型中,实现集群多阶段任务可靠性建模;最后通过数值仿真算例实现给定任务条件下的集群多阶段任务可靠性计算,并分析无人机数量n、连续失效架次k以及阶段任务中要求最少的无人机数量N_min三个模型参数对任务可靠性的影响。研究结果可为无人机集群可靠性评估和预测以及作战指挥人员实施任务规划、任务分配和决策提供技术支持。

Abstract

Aiming at the phased-mission reliability modeling problem of linear formation unmanned aerial vehicle (UAV) swarm, firstly, the phased-mission reliability model of a single UAV is established based on the accelerated failure model. Then, the quantitative results of reliability for each single UAV are substituted into the reliability model of linear continuous k-out-of-n system, and the phased-mission reliability model of UAV swarm is obtained. Finally, numerical simulation examples are showed to realize the calculation of the phased-mission reliability of UAV swarm, and the influence of three model parameters (total number of UAV n,number of continuous failure UAV k,minimum number of UAV required in a single phase N_min) on phased-mission reliability. The research results can provide technical support for the reliability evaluation and predication of UAV swarm, as well as the implementation of mission planning, mission allocation and decision-making by battle commanders.
