为了解决通信时延下关于参考状态的二阶一致性问题,提出了一种一致性算法。该算法利用Lya-punov稳定性理论,首先给出多智能体系统在固定时延下达到一致性的充分的线性矩阵不等式(LMI)判据;再给出满足一定条件的多智能体系统在时变时延下达到一致性的判据;最后,以水下无人航行器(UUV)集结为应用背景进行算法验证。运算结果表明了所提出的一致性算法和判据的有效性。该算法适用于具有时延的有向通信网中多智能体系统关于参考状态的二阶一致性问题。 相似文献

We consider several independent decision makers who stock expensive, low‐demand spare parts for their high‐tech machines. They can collaborate by full pooling of their inventories via free transshipments. We examine the stability of such pooling arrangements, and we address the issue of fairly distributing the collective holding and downtime costs over the participants, by applying concepts from cooperative game theory. We consider two settings: one where each party maintains a predetermined stocking level and one where base stock levels are optimized. For the setting with fixed stocking levels, we unravel the possibly conflicting effects of implementing a full pooling arrangement and study these effects separately to establish intuitive conditions for existence of a stable cost allocation. For the setting with optimized stocking levels, we provide a simple proportional rule that accomplishes a population monotonic allocation scheme if downtime costs are symmetric among participants. Although our whole analysis is motivated by spare parts applications, all results are also applicable to other pooled resource systems of which the steady‐state behavior is equivalent to that of an Erlang loss system. © 2012 Wiley Periodicals, Inc.

以多机协同多目标攻防对抗为背景,研究协同火力/电子战综合决策方法。提出雷达发现概率下降因子表示雷达发现能力的下降程度,来衡量电子干扰对目标威胁度的影响效果;以降低目标总体威胁为目标,建立了多机协同自卫有源压制电子干扰功率分配模型,并采用贪心算法进行求解;最后综合考虑电子干扰对目标威胁度的影响,改进了基于协同攻防的空战多目标分配算法。通过仿真分析证明该决策过程是可行的、有效的。 相似文献
