Resourcing for defense: Solving the roles and missions puzzle

One of the most important issues facing the post‐Cold War U.S. defense establishment concerns the future allocation of combat tasks and responsibilities among different branches of the armed forces. The challenge is to reduce unnecessary redundancy across roles and missions when resources are highly constrained, without compromising military effectiveness. Defining the policy problem as one of resource allocation rather than operational effectiveness, we develop a methodology for allocating roles and missions. Our methodology focuses at the highest level of force aggregation and uses a mathematical programming model to produce cross‐service cross‐mission trade‐offs that will yield the best total force combat and non‐combat potential within resource consumption constraints.

A branch and bound algorithm for sector allocation of a naval task group

A naval task group (TG) is a collection of naval combatants and auxiliaries that are grouped together for the accomplishment of one or more missions. Ships forming a TG are located in predefined sectors. We define determination of ship sector locations to provide a robust air defense formation as the sector allocation problem (SAP). A robust formation is one that is very effective against a variety of attack scenarios but not necessarily the most effective against any scenario. We propose a 0‐1 integer linear programming formulation for SAP. The model takes the size and the direction of threat into account as well as the defensive weapons of the naval TG. We develop tight lower and upper bounds by incorporating some valid inequalities and use a branch and bound algorithm to exactly solve SAP. We report computational results that demonstrate the effectiveness of the proposed solution approach. © 2011 Wiley Periodicals, Inc. Naval Research Logistics, 2011     

舰艇编队海上运输补给物资需求预测方法

按照是否与任务、事件相关,将物资需求分为两类,对于任务、事件相关物资需求的预测,将任务进行合理的分解,并根据物资消耗与任务、事件之间的关系,给出了预测的一般模型;对于与任务、事件联系不紧密的物资需求的预测,则根据历史经验及该物资固有的消耗规律,提出了经验预测模型。为了解决舰艇编队海上运输补给物资需求预测所存在的问题,利用案例推理的方法生成了预测所需的样本数据,以最小二乘向量机(LSSVM)模型为预测模型,并以岛屿进攻作战的防空弹药需求预测为例进行了实例分析。结果表明:案例推理生成的样本数据可用,选用LSSVM模型的预测结果与其他预测模型表现出了一致性,但LSSVM相对误差较小;该方法在某种程度上解决了样本数据有限的问题,适用于作战物资需求的预测问题。     

龙冈大捷:中央苏区和中华苏维埃共和国的奠基之战

中央苏区红军第一次反“围剿”的主战场,在江西永丰县的龙冈.龙冈大捷,是中央苏区和中华苏维埃共和国的奠基之战.没有罗坊会议“诱敌深入”的重大战略决策,就没有红军第一次反“围剿”战争的胜利.罗坊会议前后曾争论迭起,毛泽东运筹帷幄、决策拍板,彭德怀鼎力支持、策应启动,红一方面军第1、第3军团顺利合兵、东渡赣江,红军主力实施战略退却、小布集结,取得第一次反“围剿”的重大胜利.

Design and analysis of a scheme for the naval gun test shell entering the bore

The test shell without projectile belt is widely used in the teaching, inspection and maintenance of modern automatic naval guns. In order to ensure the normal work of each mechanism, it is very important to design the buffer and limit of the test shell during the process of entering the bore. Taking a certain type of medium caliber naval gun as the research object, the design of colloidal fluid damper and cartridge lock was proposed to ensure the reliability of entering the bore and closing the breechblock. By combining the simulation methods of computational fluid dynamics (CFD) and multibody system dy-namic (MBD), it was analyzed whether the structural design can meet the engineering requirements. The research results show that the colloidal fluid damper can dissipate a large amount of kinetic energy of the shell, and the cartridge lock can limit the rebound movement. The combination of the two ensures the smooth process of closing the breechblock. The research provides a design method for the process of the test shell entering the bore, and provides theoretical support for the feasibility of the method.     

Warfare by other means: special forces,terrorism and grand strategy

This contribution looks at the role of Special Forces in anti-terrorist operations with particular emphasis on the British Special Air Service. It argues that Special Forces have played a pivotal role in such operations since the era of Palestinian terrorism in the early 1970s. The essay looks at the operations in Afghanistan leading to the overthrow of the Taliban in 2001 and shows that the seven Special Forces involved there proved crucial to the success of the limited ground forces. In particular they served a valuable force multiplier by acting as a nexus between the regional warlords and the use of air power as well as mobile strike units against fortified Al Qaeda and Taliban positions. In the latter instance their success was mixed, involving attacks on difficult cave hideouts, though overall it can be concluded that Special Forces have demonstrated their capacity in fighting unconventional warfare against mobile and transnational terrorist groupings.     

Equality and diversity in the British armed forces: progress,challenges and prospects

The UK's changing political and legal landscape since 2000 reflecting transformations in wider society have elevated equality and diversity (E&D) issues to prominence in the public sector, including in the British armed forces. This research highlights key developments in the British military in relation to E&D, focusing both on areas of progress, and on the challenges still confronting the Forces. The findings reveal that the Forces have made significant strides in advancing E&D through the implementation of a range of policy initiatives but the persistence of discrimination, developments in the wider environment and the dilemmas raised by the strands of age and disability pose challenges. The value of this research is to increase our understanding of diversity management in a public sector institution that has been under-researched and views itself as “different,” and will be of interest to policymakers, E&D practitioners and academics in the field.
