战略导弹惯性/星光复合制导技术研究

以Kalman滤波为基础,研究了惯性/星光复合制导系统的原理和特点,并对系统进行了计算机仿真。通过将惯导系统和星敏感器所测得的战略导弹相关姿态信息进行数据融合,估计出复合制导系统的误差状态量,进而修正惯导系统的位置、速度和姿态角误差。仿真结果表明,采用惯性/星光复合制导可以有效地提高战略导弹的姿态精度。     

‘Blackmailing the army’ – ‘Strategic Military Refusal’ as policy and doctrine enforcement: the formation of a new security agent

The study shows how ‘strategic military refusal’ in Israel developed as a rational and institutional means to influence security policies. As opposed to the perspective that sees military refusal as a spontaneous individual act, the study illustrates how organizations operate to distribute military refusal in order to pressure decision-makers to change their military policies. This strategy has proven to be effective when the military is involved with groups that threaten it with refusal – which threatens the military's operational ability and its official and apolitical image. These include soldiers whose civilian authorities, rather than their military commanders, are perceived as an epistemic authority regarding security issues. The case study refers to the impact of strategic military refusal in Israel on security policies and the military doctrine. This was influenced by leftist groups, which, although they belonged to the parliamentary opposition, had dominant presence in the military ranks. Furthermore, the study examines the effect of the use of strategic military refusal on the model of military recruitment.     

Selling to strategic and loss‐averse consumers: Stocking,procurement, and product design policies

Motivated by the presence of loss‐averse decision making behavior in practice, this article considers a supply chain consisting of a firm and strategic consumers who possess an S‐shaped loss‐averse utility function. In the model, consumers decide the purchase timing and the firm chooses the inventory level. We find that the loss‐averse consumers' strategic purchasing behavior is determined by their perceived gain and loss from strategic purchase delay, and the given rationing risk. Thus, the firm that is cognizant of this property tailors its inventory stocking policy based on the consumers' loss‐averse behavior such as their perceived values of gain and loss, and their sensitivity to them. We also demonstrate that the firm's equilibrium inventory stocking policy reflects both the economic logic of the traditional newsvendor inventory model, and the loss‐averse behavior of consumers. The equilibrium order quantity is significantly different from those derived from models that assume that the consumers are risk neutral and homogeneous in their valuations. We show that the firm that ignores strategic consumer's loss‐aversion behavior tends to keep an unnecessarily high inventory level that leads to excessive leftovers. Our numerical experiments further reveal that in some extreme cases the firm that ignores strategic consumer's loss‐aversion behavior generates almost 92% more leftovers than the firm that possesses consumers’ loss‐aversion information and takes it into account when making managerial decisions. To mitigate the consumer's forward‐looking behavior, we propose the adoption of the practice of agile supply chain management, which possesses the following attributes: (i) procuring inventory after observing real‐time demand information, (ii) enhanced design (which maintains the current production mix but improves the product performance to a higher level), and (iii) customized design (which maintains the current performance level but increases the variety of the current production line to meet consumers’ specific demands). We show that such a practice can induce the consumer to make early purchases by increasing their rationing risk, increasing the product value, or diversifying the product line. © 2015 Wiley Periodicals, Inc.

美关岛基地战略前景分析

关岛是美军在西太平洋地区的重要战略支撑点,既是战略轰炸机基地,又是海军在西太主要的作战、后勤保障中心,还是海军陆战队的集结基地,军力可有效辐射西太地区。对于美军来说,关岛具有政治可持续性、地理位置优越、自身规模适宜等自身优势,同时也面临着远程打击威胁增多、军力部署集中与分散两难、盟友顾虑被抛弃等问题。美国将持续加大对关岛的军事力量建设投入,进一步加强关岛在西太的军事核心地位。     

US strategic preferences in the early twenty-first century

This article investigates how US national security planners have envisioned the emerging strategic environment during the early twenty-first century and evaluates how their perceptions of this strategic environment have changed during these years. This conceptual evolution can be seen in how defense planners define threats, identify defense priorities, and design security strategies. Five key strategic planning documents serve as the basis for this analysis and illustrate significant shifts in how the US government has envisioned its own security requirements as well as the context within which its strategic vision will need to be realized. These planning documents are: (1) Joint Vision 2020, (2) the Bush Administration's 2002 National Security Strategy of the United States, (3) the Obama Administration's 2010 National Security Strategy, (4) US Strategic Defense Guidance entitled Sustaining US Global Leadership: Priorities for 21^st Century Defense, and (5) the US Chairman of the Joint Chiefs of Staff's Capstone Concept for Joint Operations: Joint Force 2020.

带运力限制及单边时变约束下多出发机场航空战略投送兵力分配模型研究

利用民航力量由多个机场向一个目标机场实施航空战略投送时,由于各民航机场都具有运力限制约束,不可能无限制地快速投送兵力,因此,考虑了在多个出发机场存在运力限制约束的情况下,构建了"投送时间最短,动员机场最少"多目标决策模型,并给出了优化算法和算例.     

United Nations Security Council reform and the dilemmas of African continental integration

This article analyses the disunity among African states in terms of United Nations Security Council (UNSC) reform, and attributes it to the contest between South Africa and Nigeria. These two countries have been locked in a hegemonic contest for continental domination. To this end, the article notes that African unity, not in terms of protocol but on the basis of principles and cooperation, is sacrosanct in order for the African Union to make a significant contribution to the reform of the UNSC. It is asserted that the contest between South Africa and Nigeria has been symbolised by the continental leadership aspirations of the heads of state of both countries, and recommends that it be tamed through forging diplomatic and strategic partnerships between the ruling parties of these two countries. The influence of external actors on the African countries, particularly that of France, is underscored as a contributing factor in stalling the debate on the UNSC reform. It recommends that South Africa use its strategic partnership within the association of Brazil, Russia, India, China and South Africa (BRICS), particularly Russia and China as permanent members of the UNSC, to influence the realisation of the reform debate.     

The concept of logistics derived from Clausewitz: All that is required so that the fighting force can be taken as a given

This article assesses the existing literature on logistics in war, concluding that there is no satisfactory conceptual definition of logistics. It proposes a concept of logistics derived from Clausewitz's theory of war to fill that void. This is presented as a derivation because Clausewitz's distinction between (1) the use of the fighting forces (tactics and strategy) and (2) all other activities in war that were required so that forces could be taken as a given. The latter, left unnamed by Clausewitz, corresponds to a concept of logistics that proves to be an analytical peer to Clausewitz's categories of politics, tactics and strategy.
