协同空战指挥控制系统智能体模型研究 总被引:10,自引:4,他引:6
建立了由多个智能体(Multi-AgentSystem)组成的多机协同空战指挥控制系统的总体结构模型及基于信念、期望、意图(BDI)结构的单个智能体的结构模型,并针对多机协同空战指挥控制的特点,对基于BDI框架的智能体结构、智能体的内部行为、触发事件和结合作战效能的BDI解释器等形式化建模问题进行了研究。最后,指出需完成的后续工作以及相关技术问题。 相似文献

自主构形重构是分布式卫星自主运行的典型任务.将构形重构问题分解为底层控制问题和上层规划问题,给出构形重构问题的统一描述,在一种递阶控制结构中探讨基于Agent的分布式卫星自主构形重构问题,并介绍基于ObjectAgent的实现框架.针对底层控制问题,提出卫星相对运动轨道调整的螺旋控制策略,并对燃料消耗量进行估计;针对上层规划问题,采用拍卖算法完成构形重构位置分配.最后通过一个仿真实例验证基于Agent的分布式卫星自主构形重构的可行性. 相似文献

能力是规范Agent的一个重要抽象概念。本文提出了规划树概念以刻划在动态、不确定的多A-gent系统中Agent如何通过对其规划进行合理、有效的组织来实现其任务、维护某些条件。基于规划树概念,本文给出了能力概念的形式化语义定义,获取和描述了它的一些重要属性。 相似文献

由于多智能体系统(MAS)中各个Agent具有自治性、分布性和异构性等特征,导致MAS内部经常会出现冲突现象。首先,运用数学方法对MAS中存在的属性冲突进行形式化描述,并将其分为6类,针对每类冲突提出了相应的消解对策。其次,对属性冲突智能消解系统(AACIRS)流程框架进行了分析,并在此基础上建立了AACIRS系统,实现了MAS中属性冲突的消解。从而为解决MAS中Agent属性冲突提供了解决方案,为MAS的稳定运行提供了技术保证。 相似文献

Taking insurgency sponsorship as an instrument states have available for achieving foreign policy objectives, I consider how state-sponsors could best manipulate their support to maximize control of the proxy group. Building on research that models the state-sponsor–insurgent relationship using a principal–agent framework, I identify two key vulnerabilities to which the state-sponsor is exposed: adverse selection and agency slack. As an original contribution to the literature on state-sponsorship of insurgency, I articulate reasons why certain forms of support would be most conducive to overcoming these problems and illustrate how South Africa and Iran used those kinds of support to influence the behavior of their proxies, RENAMO and Hezbollah. Additionally, I consider how this principal–agent analysis of insurgency sponsorship also could apply when the principal is an international terrorist organization such as al Qaeda. Finally, I address the relevance of these ideas to two contemporary conflicts taking place in Syria and the Congo. 相似文献

七氟丙烷贮存容器贮存压力的保持是保证灭火剂能在规定时间内有效覆盖防护区的关键因素之一.通过理论分析,认为氮气和七氟丙烷气体分子的相互扩散是导致贮存压力下降的主要原因.并通过对两个典型案例的分析,从氮气充装工艺等角度对如何保持灭火剂充装后的贮存压力提出了建议. 相似文献

We study the optimal contracting problem between two firms collaborating on capacity investment with information asymmetry. Without a contract, system efficiency is lost due to the profit‐margin differentials among the firms, demand uncertainty, and information asymmetry. With information asymmetry, we demonstrate that the optimal capacity level is characterized by a newsvendor formula with an upward‐adjusted capacity investment cost, and no first‐best solution can be achieved. Our analysis shows that system efficiency can always be improved by the optimal contract and the improvement in system efficience is due to two factors. While the optimal contract may bring the system's capacity level closer to the first‐best capacity level, it prevents the higher‐margin firm from overinvesting and aligns the capacity‐investment decisions of the two firms. Our analysis of a special case demonstrates that, under some circumstances, both firms can benefit from the principal having better information about the agent's costs. © 2007 Wiley Periodicals, Inc.
