基于模板的军事概念模型描述与设计

首先分析军事概念建模存在的问题,然后提出两个阶段、四个步骤的建模思路,在此基础上通过基于模板的概念模型描述方法,将概念建模区分为实体元模型、动作元模型、关系元模型、属性元模型和数据元模型,通过对上述元模型的建模完成对仿真对象的概念建模。     

BOOK REVIEWS

This study examines how young people who have joined the South African National Defence Force (SANDF) on the two-year Military Skills Development System (MSDS) contract experience military service, and the effect this has on their ability to readapt to civilian life. The first part of the study examines the theoretical debates associated with military socialisation and reintegration into civilian life. Hereafter, the findings are presented in terms of the experiences of MSDS privates serving in the infantry, those that have left, and the perceptions of employment agencies in terms of the marketability of military skills. The conclusion is reached that MSDS members experience their two years in the SANDF as life-changing, that this affects their ability to reintegrate back into civilian society, and that the skills acquired during military training is of limited market value. The conclusion is reached that more needs to be done to assist these young military veterans to adapt to civilian life and to augment their military experience with more marketable skills to enable them to find gainful employment.     

Country survey IV: Pakistan

This paper examines the role of the military in Pakistan, particularly in regard to civil‐military relations and defence industrialisation. Pakistan's military expenditure is relatively high, but apart from investment multipliers, little of this spending filters through to the civil sector. Pakistan's defence‐industrial strategy centres on rebuild and Chinese technological collaboration. However, while this ‘capital‐saving’ approach has merit, the strategy has thus far failed to stimulate broader civil development linkages. A conclusion of this paper is that Pakistan is failing to maximise the strategic dual‐use benefits of integrating civil‐military activity.

The challenges of Iraq: putting US Army stability operations doctrine to the test

The US Army develops doctrine as a set of fundamental principles that guide its actions in support of national objectives. Recently, those national objectives required stability operations, with increasing scope and frequency. This study examines whether existing US Army doctrine adequately fulfilled its role as a guide to tactics in addressing the challenges that Army forces faced in the first 15 months of the war in Iraq. Field Manual 3-24 Counterinsurgency has remedied many deficiencies, but several remain to be addressed to offer commanders better guidance in the face of the many complex challenges they face in stability operations.     

The use of undercover military units in counter-terrorist operations: a historical analysis with reference to contemporary anti-terrorism

This article examines the use of specialised plain-clothes military units in counter-terrorism, concentrating on examples involving liberal-democratic states. It analyses the benefits and problems arising from clandestine military activity, focusing in particular on British army units (notably 14 Intelligence Company and the Force Research Unit in Northern Ireland). The article concludes by arguing that such formations have a clear utility – notably in gathering intelligence on terrorist groups – but other aspects of their role are inherently controversial (notably in cases where undercover soldiers use deadly force against suspected terrorists). It also states that plain-clothes military operations need to be conducted on the basis of accountability, both for strategic reasons, and also in accordance with the norms of liberal democracy.     

Controlled warfare: how directed-energy weapons will enable the US Military to fight effectively in an urban environment while minimizing collateral damage

US military operations are increasingly conducted within urban environments and with these operations come the risk of increasing the number of civilian casualties and infrastructure damage. The use of non-lethal weaponry, such as directed-energy weapons, is one method for minimizing collateral damage. This method enables US military forces to effectively fight within urban environments through force escalation capabilities. Using a series of historical examples and future scenarios for urban warfare, this article highlights deficiencies affecting military capabilities in military urban operations, addresses the consequences of collateral damage, assesses the effectiveness of directed-energy weapons in military urban operations and encourages further funding, research and integration of non-lethal weaponry, such as directed-energy weapons, within the US military.     

STRATEGIC DEFENSE AND ATTACK FOR SERIES AND PARALLEL RELIABILITY SYSTEMS: COMMENT

The contest-theoretic literature on the attack and defense of networks of targets focuses primarily on pure-strategy Nash equilibria. Hausken's 2008 European Journal of Operational Research article typifies this approach, and many of the models in this literature either build upon this model or utilize similar techniques. We show that Hausken's characterization of Nash equilibrium is invalid for much of the parameter space examined and provides necessary conditions for his solution to hold. The complete characterization of mixed-strategy equilibria remains an open problem, although there exist solutions in the literature for special prominent cases.     

Sovereign debt,deficits and defence spending: the case of Greece

Abstract

The outbreak of the sovereign debt crisis at the end of 2009 in Greece led to a severe recession, and constant economic problems. This paper investigates military expenditure among others as a potential factor to the growth of sovereign debt in Greece over the period 1960 until currently. Our empirical findings suggest that high deficits, inflation and military spending have been the primary causes of debt growth in Greece. The structural break models reveal a much higher effect of deficits and inflation in the post-1990 period while the threshold switching regression, based on the level of sovereign debt, indicate that for levels of debt-to-GDP ratio above 90% deficits, inflation and military expenditures had significantly more pronounced effects on government debt changes.
