基于改进TOPSIS法的维修保障系统效能评估研究

维修保障系统涉及因素众多,对其进行效能评估是一项非常复杂的问题.在分析TOPSIS及其改进方法的基础上,构建了维修保障系统效能评估指标体系,应用改进TOPSIS法对维修保障系统效能进行了综合评估,并将评估结果与AHP和突变评价法的结果进行比较,结论一致.为维修保障系统效能评估问题寻求出一种新的方法,其评估结果可为决策提供定量依据.     

模糊逻辑系统在船舶风险评估中的应用

为了合理进行船舶风险评估,提出了一种基于模糊逻辑系统的船舶风险评估方法.根据模糊逻辑系统的基本原理,建立了船舶风险评估的模糊逻辑模型;按照国家标准、规范,并结合经验建立了风险指标的模糊集合、风险矩阵及模糊规则,然后进行了模糊推理,得到了系统的风险等级,并制定了预防风险的措施.以某艇消防系统的风险评估为例,证明了其能够合理地评估出系统的风险,可为决策提供参考.     

面向决策的一体化建模方法及其在兵力筹划中的应用

在对军事决策问题的主要特点进行分析的基础上,提出从军事概念模型到数学模型再到定性推理模型的一体化建模思想.以空军航空兵遂行直接航空火力支援任务为想定背景,根据EATI模板,利用基于UML的Rose工具依次对想定任务的实体、任务、交互等进行分析;对于兵力筹划中的结构化问题建立了机会约束多目标规划数学模型;对于非结构化问题则构造了推理机,推理机体现了定量与定性相结合的决策分析思想.最后,以一个实例验证文章思路的可行性.     

基于"联合指数"的联合作战编组集团能力量化分析

随着科学技术的发展,以信息技术作为联结手段、由各军兵种部队参加的一种新的作战方式———联合作战,已经正式登上人类战争的舞台.而对于联合作战编组集团的作战力量的量化分析,是摆在联合作战模拟人员面前的一个重要而紧迫的任务.文中以“联合指数”方法为基础,就联合作战编组集团能力量化问题特别是对不同武器装备作战单元的能力量化进行了探讨.     

动态灰色时序系统 DGTS 及其在安全策略规范中的应用

设计安全策略模型时应考虑安全策略的时序特性和灰色特性,还应综合考虑保密性、完整性和可用性三方面的需求。已有的安全模型没有描述时序性和灰色特性,而且一般只侧重描述保密性或完整性。为此,本文提出了动态灰色时序系统（简称ＤＧＴＳ）。本文详细描述了ＤＧＴＳ,以及基于ＤＧＴＳ的动态语义设计的灰色时序安全策略规范语言ＧＴＳＬ。     

Boko Haram terrorism in Nigeria

Since the July 2009 Boko Haram terrorist outburst in Nigeria, there have been increasing questions on the phenomenon in the country. There has not been any substantial analysis on the emergence of the Boko Haram group and its terrorist activities in Nigeria as the out-rage continues. This study is advanced to explain the phenomenon of Boko Haram terrorism in Nigeria. It employs the levels of analysis framework popular in the field of international relations to explain the terrorism at three major levels: individual, state and international. The study relies on dependable news reports, which include interviews with key actors relevant to the subject matter, and finds that Boko Haram terrorism has its roots in the ideology and motivations of its founder and members, the failures and deficiencies of the Nigerian state, and the modern trend of religious terrorism in the international system.     

Defence spending and growth in turkey 1954–1993: A causal analysis

This paper investigates the causality issue between military expenditure and growth in the case of Turkey, a strategically located developing country, for the period 1954–1993. Results reported herein reveal the absence of any causal ordering between the variables in question.     

Is there a Greek‐Turkish arms race?: Evidence from cointegration and causality tests†

Greece and Turkey are both members of NATO and are two of the principal players in the Balkan region. Their respective defence burdens (i.e. the share of military expenditure to GDP) are the highest in NATO. Their bilateral relations are marred by serious friction and conflict of interest and have on a number of occasions come close to an armed confrontation. Their strategic interaction and mutual weapons build‐up has recently attracted the attention of researchers in the field testing the hypothesis of a Greek‐Turkish arms race with conflicting results. This paper, using cointegration and causality tests, finds evidence of a systematic armaments competition between the two countries provided that a defence policy regime shift estimated to occur in 1985 is explicitly taken into consideration. This policy regime change is associated with the stagnation of defence spending in Greece owing to the gradual deterioration of Greek public finances over the last decade.     

Democracy and peace: Reply to oneal and russett

The criticism of James, Solberg and Wolfson (JSW) (1999) by Oneal and Russett (OR) is not responsive to the methodologica] issues at stake. JSW argued that war is an endogenous feature of the world political and economic system. If its causes are to be measured, it must be as a structural equation in a simultaneous system. Wedded to the idea that “democracies never fight each other,” OR rely on a single equation to justify their view. JSW claim that such an equation may be an ad hoc reduced form with no causal implications unless the equation is explicitly identified as a structural equation. JSW expand the model to explain democracy and conflict as two endogenous variables. JSW do not claim to have discovered the true relationships between these variables by their minimal expansion of the structural relation. They do show that unless these (and other) variables are treated as part of a system, the results are unstable, contradictory, of minimal size and not a reliable guide to public policy.
