摘要: 多机协同目标分配问题是无人机UAV(Uninhabited Aerial Vehicle)研究 中一个重要的问题.考虑UAV差异、目标差异及战场态势对目标分配的影响,建立了多机 协同目标分配问题的数学模型.提出基于满意决策的目标分配算法,通过搜索个体满 意集合获取群体优化的目标分配方案.对多目标分配问题,将攻击方案作为个体满意集 合的元素扩展了基于满意决策的目标分配算法.为适应更大的问题空间的求解需求,提出递 阶分配框架,并将满意决策方法用于递阶分配.计算结果表明,算法能有效提 高搜索效率,并得到很好的优化效果.Abstract: A key problem addressed in study of uninhabited aerial vehicle (UA V) is to coordinated assign targets in multi-UAVs. The mathematic model for mul t i-UAV cooperative target assignment problem was built, when assigning targets i n multi-UAVs, the model considered about effect of the battle field situation, a n d differences in different UAVs and targets. A multi-UAV target assignment algo r ithm based on the satisficing decision theory was presented. Each individual pro posed its satificing set, the algorithm searched the global optimal assignment s cheme on all individual satisficing sets. To settle the multi-target assignment problem, the algorithm was applied by taking the atta ck scheme as the element of the individual satisficing set. To expand the proble m size, a hierarchical structure was presented by which the algorithm was extend ed to the hierarchical form. The method evidently can improve the searching efficiency and obtain the optimal results.
