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.
