装备一体化设计中基于约束和实例的维修性冲突解决方法研究

分析了装备一体化设计过程中维修性约束及维修性冲突的特点。在此基础上,结合并行设计、协同设计领域内的相关研究,提出了基于约束和实例的维修性冲突解决方法,该方法发扬了约束法和实例法解决冲突的优势,弥补了单一解决方案存在的不足。最后以某型飞机电动机设计为例对该方法进行了说明。     

一种并行工程冲突管理原型系统的开发

并行产品开发模式下,由于设计者知识的局限性、系统资源的有限性等多种因素的限制,冲突的产生是不可避免的。为减少冲突,提高产品开发效率,文章以坦克火控系统的研制为背景,用面向对象的程序设计语言Visual Basic 6.0编写源程序,通过VB6.0附带的工具程序“可视化数据管理器”建立数据库,开发了一种并行工程冲突管理原型系统。该系统界面友好,功能强大,不仅有效地检测和解决了产品开发、过程中可能出现的冲突,而且它对面向数据库的数据处理系统的开发,具有一定的参考价值。     

Does civil war hamper financial development?

We examine how armed conflict effects financial development in a cross-country setting using dynamic panel data analysis in a panel of 66 developing countries for the period 1985–2010. Financial development is measured by M2 as a share of GDP, and credit allocated to private sector by banks as a share of GDP. Our findings suggest that armed conflict has a significant adverse effect on financial development. Simultaneously, the quality of governance is always highly significant and conducive to the financial development. The quality of governance is more salient in determining financial development compared to low- and medium-intensity armed conflict; however, the quality of governance cannot entirely offset the adverse impact of high-intensity armed conflict on financial development.     

Homes for heroes? Assessing the impact of the UK’s Military Covenant

The British Military Covenant can be located in and from many sources and from 2011 onwards in primary legislation. This article argues that the provision of military housing amounts to an early test of how the military covenant is understood and used by those involved in defence policy, and those in the armed forces affected by it. It finds that housing was a prominent feature of how service personnel understood how they were valued, but was not explicitly understood as a covenant issue by those personnel or the officials in charge of the Defence Estates. We locate three reasons for this: (1) the covenant has been poorly translated from aspiration into policy practice, (2) the covenant is unevenly understood across its stakeholders which has the effect of generating disappointment through misaligned expectations, (3) those engaged in the reform process surrounding the Defence Infrastructure Organisation (DIO) saw the covenant as a means to energise reform. Ultimately housing was seen as a dry and technocratic business area and thus an issue ripe for being refracted through the covenant was ultimately left outside of its remit.     

Majority rule,minority issues: The Macedonian question in the Dekemvriana

This article examines the role of the Macedonian Question in the 1944 December Uprising (Dekemvriana) in Greece. While the Dekemvriana is commonly portrayed in right–left terminology in the historiography, this article argues that part of the reason for the left’s failure was their inability to manage the Macedonian ethnic component of the struggle, either within their armed forces or in their relationship with Yugoslavia. As such, this article integrates the early phases of the Greek Civil War into the broader literature on minorities in civil conflict, while simultaneously exposing some of the myths about Macedonian involvement that result from its contemporary political ramifications.     

基于遗传算法的协同多目标攻击空战决策方法

多机协同多目标攻击是未来空对空作战的一种重要形式。首先建立了多机协同空战的自主优势矩阵 ,并依据多人冲突决策理论构造了空战的总体优化指标向量 ,然后针对其他优化算法的不足 ,提出用遗传算法优化该指标向量 ,实现多机协同多目标攻击空战决策 ,最后对 2∶ 2空战进行了仿真。仿真结果证明了上述思想的正确性。     

基于随机搜索策略的中继卫星调度方法

高质量的调度方案不仅能满足用户的需求,还能为中继卫星系统的计划编制提供科学的决策手段和依据。针对日益多样化的用户需求,采用全新的中继卫星调度应用模式,允许用户提交多个可以滑动的时间窗口。面向这种调度模式,考虑中继业务中任务调度的灵活性和任务间的冲突,构建考虑多滑动窗口的中继卫星调度模型,并设计基于随机搜索策略的中继卫星调度算法。算法包括任务资源匹配与邻域生成、可用时间段生成、任务冲突分析、邻域搜索与冲突消解以及资源与任务集更新5个算子。通过仿真实验将该算法与基于时间自由度的启发式算法进行对比,验证了算法的有效性。     

Competing for Control over the State: The Case of Yemen

Abstract

This article argues that the current conflict in Yemen is better understood as a competition over who controls the state, rather than as a conflict between the state and a non-state actor. It traces the development of the Houthis and shows how the movement managed to seize key government institutions. However, the Houthis lack internal legitimacy and have not been able to position themselves as a nationally relevant political elite. The fragmentation of the Yemeni state has resulted in a shift to more localized struggles over access to resources and power that involve both internal and external actors.     

From Westphalian Failure to Heterarchic Governance in MENA: The Case of Syria

Abstract

The problematic export of the Westphalian system to MENA is examined, taking Syria as exemplar. The export model is juxtaposed to actual non-lineal trajectories, semi-sovereignty and hybrid or failing states. This is manifested in post-uprising Syria in failing statehood, fragmented and overlapping governance, permeable and collapsing borders, the loss of sovereignty to trans-state movements, “competitive regime-building” between the Asad regime and jihadist warlords, and “competitive interventionism” by external powers filling the governance vacuum with their own proxies. The result is heterarchic zones of limited statehood in which state sovereignty is contested by both international (supra-state) penetration and sub-state fragmentation.     

Israel’s Security Nexus as Strategic Restraint: The Case of Iran 2009–2013

This article examines the debates in Israel between 2009 and 2013 over Iran’s nuclear programme as a reflection of a particular type of civil–military or civil–security relationship. It analyses how key actors within that relationship – particularly those with an intelligence background – engaged with media outlets in Israel and further afield to influence domestic and international opinion over how best to contain Iran’s nuclear ambitions. In so doing, it seeks to address one fundamental question: are governments in Jerusalem any longer the final arbiters over deciding what is in the national security interests of the State of Israel?
