简介:复杂解决问题要求多样的专家知识和多重技术。为了解决如此的问题,人的专家包括两个的复杂多代理人系统和自治代理人,在许多应用程序域被要求。最复杂的多代理人系统在开的领域工作并且包括各种各样的异构的代理人。由于代理人的异质和工作环境的动态特征,代理人的专家知识和能力可能很好没在这些被估计并且介绍系统。因此,怎么从人、自治的专家发现有用知识,为专家的能力做更多的精确评价并且发现解决到来的问题(“专家采矿”)的合适的专家是在区域ofmulti代理人系统的重要研究问题。在这篇论文,我们在混合多代理人系统为知识和专家采矿介绍一条基于本体论的途径。在这研究,本体论被雇用描述系统的知识。当系统处理到来的问题,知识和专家采矿进程被执行。在这条途径,我们在multi-agentsystems嵌入更自我学习、自动调节的能力,以便在发现多代理人系统的异构的专家的知识帮助。
简介:这篇论文问一个新问题:我们怎么能控制集体行为组织ofself的多代理人系统?我们试着由建议新观点called'SoftControl'回答这个问题,它把存在代理人的本地规则放在系统。我们由案例研究显示出软控制的可行性。考虑简单却典型的分布式的multi-agentmodel由Vicsek等求婚了。为鸟结队:每个代理人以一样的速度,但是与基于它的自己的标题的一般水准用一条本地规则被更新的不同标题和它的邻居的标题移动。这个模型的大多数研究关于self-organizedcollective行为,例如标题的同步。我们想要由软控制在这个组的集体行为(标题)干涉。一个指定方法是增加一个特殊代理人,叫了一个“党羽”,它能被我们控制,但是被另外的代理人当作一个平常的代理人。我们为党羽构造一条控制法律以便它能同步整个组到一个客观标题。这条控制法律被证明是有效经分解并且数字地。注意软控制与分布式的控制的途径不同。在分布式的系统干涉是一个自然方法。它可以在复杂系统的控制上拿出许多有趣的问题和挑战。

简介:这份报纸集中于多代理人系统(质量)的formability。这个问题涉及有能力驾驶包含到需要的形成的MAS的一个协议的存在,并且这样,具有在设计形成协议的必要重要性。Formability一妈取决于几个关键因素:动态结构,连接拓扑学,需要的形成的性质和可被考虑的控制设置了的代理人。这里考虑的团的代理人被一个将军描述连续线性时间不变(LTI)当模特儿。由使用矩阵分析和代数学的图理论,LTI团的formability上的一些必要、足够的条件被获得。这些条件关于一些典型、广泛地使用的可被考虑的协议集合在某感觉描绘formability,连接拓扑学,形成性质和代理人动力学的关系。
简介:自从它能改进生产率,一个有效预示的程序对复杂设备的预兆的维护关键,延长设备生活,并且提高系统安全。这份报纸基于背繁殖为精确失败预后建议一种新奇技术神经网络和量多代理人算法。由量计算理论和多代理人系统的广泛的研究启发了,这种技术采用量多代理人策略与包括健康评估,合作,转线路和变化的量代理人表示和几操作的主要特征,为神经网络到的参数优化避免象困住到本地最小的慢集中和责任那样的缺乏。验证建议途径的可行性,几个数字近似实验第一被设计,在哪个以后从辛辛那提大学的实验室的轴承的真实震动的数据被分析并且过去常为一个给定的未来点估计健康条件。结果是鼓励并且显示介绍预报方法有潜力在工业机械为失败预言作为一个评价工具被利用。
简介:在这份报纸,一个分布式的一致协议在一般固定指导拓扑学下面与测量噪音为分离时间的单个整数的多代理人系统被建议。变化时间的控制获得令人满意随机的近似条件被介绍稀释噪音,这样靠近环的多代理人系统是内在地一个线性变化时间的随机的差别系统。然后,吝啬的方形的一致集中分析基于Lyapunov技术被开发,并且Lyapunov函数的构造特别不要求为二次的Lyapunov功能的存在假定的典型平衡网络拓扑学条件。因此,建议一致协议能对更一般的联网的多代理人系统适用,特别地当在代理人之间的双向或平衡的信息交换没被要求时。在建议协议下面,每个代理人的状态在吝啬的平方收敛到其数学期望是起始的状态珍视的代理人的加权的一般水准的一个普通随机的变量,这被证明;同时,随机的变量变化被围住。
