互联网上越来越多软件系统呈现出社会与技术交融、环境多样和开放、系统动态和演化等特点,如何支持这类复杂软件系统的构造是软件工程面临的一项重要挑战。通过将社会技术系统视为多Agent组织,把社会组织学的概念和思想引入到面向Agent程序设计范畴,提出了以Agent、组织、角色和职位为核心的基于组织程序模型来支持社会技术系统的开发;通过对多Agent组织不同层次动态性的识别和分析,设计了一组程序设计机制来实现社会技术系统的动态演化;包括角色绑定和组合机制、基于角色的交互机制以及组织的自我管理机制。基于上述模型和机制,提出了社会技术系统程序设计语言OragentL,给出了OragentL程序在组织、角色和组合三个层次的语法形式定义,介绍了OragentL的编译器及其运行支撑环境OragentBurg,并通过案例分析和演示展示了研究成果的有效性。 相似文献

为了开展未来信息化战场情报侦察先期概念技术演示,通过采用基于多Agent的仿真方法,把情报侦察系统的内部组元直接映射成相应的Agent,研究了基于多Agent的战场情报侦察仿真系统总体框架和仿真系统基本单元Agent的框架;并进一步研究了Agent之间的任务分解、信息交换、选择与排序、分配过程。构建的仿真模型,以Agent的表现形式获得了对战场情报侦察这一客观、复杂过程的深刻认识,从而可实现对这种动态作战环境行为的仿真。 相似文献

基于角色的访问控制(RBAC)机制中角色分层不能反映部门的组织结构、不适用大量用户的系统。通过引入用户组使系统的组织层次在用户组的层次结构中得到反映,对用户组的授权代替了组中所有用户的授权,解决了部门权限管理和大量用户的授权问题。基于用户组的访问控制模型在灵活和可扩展性、可接受性、机制的经济性方面具有明显的优势。 相似文献

目前,采用基于Agent建模(Agent-Based Modeling,ABM)方法研究战术级分队层次作战系统建模,存在如何直观形象而准确地表达与实现多Agent组织模式的问题。着眼军事需求,从如何建立Agent交互链的新角度来开展作战系统建模问题研究,推动ABM方法的创新发展,深化Agent和多Agent系统(Multi-Agent System,MAS)技术研究。通过提出规范、实用的Agent交互链形成过程,确立了交互链中的链节点Agent的层次化变换机制,揭示了链节点Agent聚合/解聚和交互链结构约简/扩充同步变换的工作机理。研究结果表明:与一般的ABM方法相比,Agent交互链的形成及其链结构变换,是一种更好地实现战术级分队层次作战系统建模的新途径。 相似文献

In the Post-Bipolar Era the growing complexity of the military operations requires a new approach for the resolution of international crises. Since the end of the Cold War, peace support operations (PSO) have become the mainstay and principal occupation of most Western armies. At the same time, Italy has been one of the most important actors in such an area. The article focuses on the cooperation between military and civil components (a process called CIMIC) as a key variable in the Italian PSOs. We will analyse in detail the main lessons learned from past military interventions as well as the general context in which new tendencies are taking place. The maintaining of a minimum security frame becomes essential to fulfil activities ‘collateral’ to the mission: reconstructing services and infrastructure, food distribution, water and medication, law and order, de-mining, training of local forces, and supporting local institutions. These are the main tasks to obtain thrust and support from the population. 相似文献

Energy continues to serve as the bedrock of modern economies and the main driver of modern society. For Africa, the production and supply of energy resources such as crude oil, natural gas, uranium, coal, biomass, biofuels and other renewables are an important source of employment, rents, taxes, royalties and profits. This sector brings in several tens of billions of dollars of revenue annually. The production and delivery of such resources, however, depend on critical infrastructures such as pipelines, refineries, processing plants, terminals, rigs, electrical energy pylons, substations, pump stations, vessels, and tankers. These infrastructures have been attacked by terrorists, insurgents, vandals and saboteurs, all of whom see them as targets against which to register their grievances and extract concessions from the state. This paper is a chronological account of some of the documented incidents of terrorism, insurgency, kidnapping, destruction, sabotage, and human casualties suffered in the oil and gas sectors in Africa between 1999 and 2012. It is based on data extracted from the databases of the RAND Database of World Terrorism Incidents and the University of Maryland's Global Terrorism Database (GTD). 相似文献

This article demonstrates the inconsistent and wavering Soviet attitude towards national liberation movements in general and the Palestinian organizations in particular. Until the late 1960s, the Soviets viewed these organizations with suspicion, hesitating to engage in political dialogue with them. However, in the 1970s, political and military events in the region, as well as modifications in the Kremlin's Cold War strategies, led to a general shift towards the Middle East in Soviet foreign policy. Soviet leaders showed increased willingness to provide certain Palestinian organizations with arms with which to conduct terrorist activities against Israeli, pro-Israeli, Jewish and Western targets. The article explores the complex relations between Palestinian organizations and the USSR in the field of international terror. The study also exposes and analyzes the nature and content of Soviet–Palestinian arms dialogues and transactions. It provides clear evidence that Soviet policymakers and other luminaries were fully informed of, and sometimes directly involved in, these transactions and dialogues at the highest levels. 相似文献

The September 11 global crisis prompted by the attacks on the World Trade Center and the Pentagon raises major questions concerning the nature and trajectory of terrorism in the post-Cold War global order. Hitherto, terrorism has been largely debated by analysts at the level of nation states. Terrorist and insurgent movements have also been largely anchored in nationalist and ethnic power bases even when they have sought to mobilise a transnational ideological appeal on religious or class grounds. There have been a few exceptions to this pattern such as the alliance between the German Baader-Meinhof group and the Japanese Red Army Faction, but even such international alliances as this did not, until at least the 1980s, presage anything like a global terrorist network necessitating a global strategic response. This study examines terrorism and global strategic responses. 相似文献

This article analyses to what extent the Burmese KNU insurgency made use of external support from states, refugees, and diasporas. Based on extensive fieldwork it is concluded that support from neighbouring states and refugees has for years kept the Karen rebellion alive. Western countries perceived forms of resistance to the illegitimate Burmese regime as just and have therefore played a crucial role in the continuation of conflict in Karen State. It is important that policymakers and donors as well as executing organizations continue to reflect critically on the way they exercise their work. 相似文献

The US Army has two approaches to counterinsurgency operations in Afghanistan. One is hard, or combat-focused, and the other is soft, or development-focused. This study examines two US Army task forces deployed to Panjwai District, Afghanistan from 2012 to 2013. CTF 4-9 and 1-38 offer a meaningful comparison because they pursued these contrasting approaches among the same population and against the same enemy at the same time and place. The study compares each unit’s approach and finds that neither approach was successful absent the other. The article concludes by recommending further research into combining the approaches at the operational level. 相似文献
