攻击机首攻概率模型

攻击机在首次进入攻击时完成作战任务的概率(首攻概率)是评估空军武器进攻装备作战效能的基础。从无对抗情况下攻击机的作战过程入手,分析建立了攻击机机载空地武器可攻击区的数学模型,在此基础上建立了无对抗情况下攻击机的首攻概率模型,并对所建立的概率模型进行了有效性分析。     

论消防法中责令停产停业处罚的实施主体

消防法中责令停产停业处罚的决定主体应当包括人民政府和公安消防机构。其中 ,重大的责令停产停业处罚的决定主体应当是地方县级以上人民政府而不是公安消防机构。这是由重大的责令停产停业处罚的严厉性、对经济和社会生活影响的重大性、受处罚组织的特殊性以及处罚实施主体权限的法定性决定的 ,也与地方人民政府的行政管理职能相适应 ,并且符合我国的立法例。责令停产停业处罚的执行主体应当是公安消防机构。

测试性增长中资源优化配置模型及求解

良好的测试性设计对系统维修性具有重要意义,测试性增长试验通过一系列测试性设计缺陷发现和纠正措施,可保证系统测试性指标达到设计要求。针对基于延缓纠正的测试性增长过程中的资源配置问题进行研究,基于增长试验目标是否明确和试验资源是否受限制问题构建资源优化配置模型,并提出一种基于拉格朗日松弛和本地搜索的快速优化算法。仿真结果表明:该模型能够有效指导测试性增长中的资源优化配置问题,所提混合优化方法能够高效、准确地求解整数规划问题。     

面向能力需求的武器装备组合规划模型与算法

针对武器装备组合规划中存在的选择难、规划难问题,在给定能力需求的条件下,从分析装备的组合变更对整体体系的影响出发,考虑了总的经费预算、年度费用分配、装备规划周期等约束,以能力差距和发展风险最小为准则,构建了双目标优化模型,并设计了基于差分进化和非支配排序的遗传算法的求解算法,获得模型的Pareto解。通过逼近理想解排序法方法从所求Pareto解中求得令决策者满意的折中解。通过一个具体示例验证了模型和算法的有效性,能够为武器装备组合规划提供辅助决策。     

WHILE WAITING FOR THE PROTOCOL

The Biological Weapons Convention (BWC) regime currently suffers from a lack of effective compliance procedures. Because a legally binding compliance protocol to the BWC is not available, other measures are needed to stabilize the regime against the risk of violations of its rules. The Treaty on the Non-Proliferation of Nuclear Weapons, the Chemical Weapons Convention, and the experiences of UN inspection teams show that among the necessary components of effective compliance mechanisms are an intermediary level between bilateral consultations of states parties and involvement of the UN Security Council as well as independent assessment capabilities. This article suggests that the UN Secretary General could assume such an intermediary function and, using the authority contained in Article 99 of the UN Charter, could investigate not only alleged use of biological weapons but also alleged breaches of the BWC. A standing expert unit in the Department for Disarmament Affairs could provide the independent expertise necessary for such investigations. Such a compliance mechanism could provisionally help stabilize the BWC regime until a permanent compliance system can be agreed.     

舰炮对海上集群小目标射击的毁伤概率

海上集群小目标是水面舰艇面临的主要威胁之一。以单管大口径舰炮对海上集群小目标射击作为研究对象,对集群目标进行了等效处理,分析了弹种、引信和装药的选择以及效力射中的表尺分配问题,提出多表尺效力射方法,利用该方法对海上集群小目标射击的毁伤概率进行了分析。结果表明,采用该方法并使用空炸榴弹或杀伤爆破弹,可有效破坏敌运输工具,杀伤其有生力量。     

Jihad Against Palestinians? The Herostratos Syndrome and the Paradox of Targeting European Jews

Abstract

This paper addresses the waves of mass killings recently perpetrated by individuals with a weak or nonexistent ideological motivation, whose acts either appear to contradict their purported political cause or are admittedly driven by a quest for notoriety. Examples range from killers who have been waging jihad against European Jews to unattached mass killers such as the Germanwings pilot to the perpetrators of mass school shootings in America and worldwide. We argue that these phenomena can be understood as instances of the Herostratos syndrome, which has been known for thousands of years as characterizing the behavior of people who seek to survive in the collective memory by excelling in their infamous acts. We provide a model of hybrid killers which accommodates the Herostratic motive alongside a political motive and characterize a well-behaved Nash equilibrium where Herostratic killers are competing with one another with a view to make a name for themselves in infamy. The policy implications point towards reducing the publicity the killers enjoy, thus frustrating their quest for notoriety.     

层次分析法的水下航行器维修性指标分配方法

基于层次分析法的水下航行器维修性指标分配方法把层次分析法应用到水下航行器维修性指标分配方法中,即邀请专家对故障的检测和隔离方式、可达性、可更换性和测试的困难等级进行两两比较,得到评价矩阵,据此,可以得到分配结果.这种方法克服了按故障率和设计特性分配法在设计特性相差不大时存在的缺陷,把定性分析与定量分析相结合.在设计初期即明确设计目标,除了考虑到单元的故障率还兼顾了初期设计过程中的不确定性.将这种方法应用于某水下航行器的维修性分配,结果表明,该方法具有实用价值.
