为了综合分析雷达的生存效能,通过调整非关键因素和不确定因素的基本可信度对证据理论中证据合成规则进行了改进,并基于改进D-S证据理论提出了雷达生存效能评估模型.改进后的证据合成规则不仅减小了证据的冲突,而且仍然满足证据的基本可信度之和为1的基本要求,保持Dempster合成规则所具有的可交换性.通过雷达生存效能模型应用的一个实际例子计算表明,证据理论是一种科学的效能评估方法,具有可行性和实用性,改进后的证据合成规则能够较好地分析雷达的生存效能. 相似文献

基于云模型的导弹信息作战指挥效能评估 总被引:1,自引:0,他引:1
针对导弹信息作战指挥效能评估中既包含定量指标,又包含定性指标,而对这些指标进行科学合理地统一评价尚存在很多困难的问题,运用云模型对其进行了研究。分析了导弹信息作战指挥能力的指标体系,介绍了云模型的相关理论,并给出了运用云模型进行效能评估的详细算法,利用云发生器得到了最终的评估结果。最后给出了一个评估实例,结果证明该方法有效可行,能很好地解决效能评估中定性语言到定量值之间的转化问题。 相似文献

从依附理论到依附发展理论的思考——析发展中国家在经济全球化中的道路取向 总被引:1,自引:0,他引:1
经济全球化是当今世界的一大潮流,如何利用经济全球化这一有利条件,充分发挥发展中国家的后发优势,促进经济和社会发展是发展中国家面临的一个重大课题.依附发展理论是关于发展中国家道路取向的一个重要理论派别,它起源于依附理论.依据依附理论的产生、发展过程,指出在经济全球化背景下发展中国家迅速发展所面临的有利和不利条件,应当采取的正确做法,指明了发展中国家的发展道路取向. 相似文献

基于模糊集理论和D-S证据推理的空袭目标识别 总被引:2,自引:2,他引:2
目标识别是防空作战指挥过程中信息处理的一个重要环节。在基于模糊理论目标识别基础上,引入D-S证据理论,通过对模糊隶属度进行重新分配,较好地克服了随机因素的影响,可望进一步提高对空中目标的正确识别率。 相似文献

This article presents a proposed theory of how war economies are formed and maintained, as well as an integrated policy framework to guide the dismantling of war economies emanating from the proposed theory. Additionally, six potential areas for future research pertaining to the dismantling of war economies are also presented. 相似文献

This paper analyses the financial and war‐spending policies of a state that faces a conflict in which defeat would result in the loss of sovereign power and in which the material consequences, conditional on avoiding defeat, are stochastic. The analysis takes explicit account of the historical experiences of lenders, who face debt repudiation if the state to whom they have lent is defeated and who also face partial default if the material consequences of the war are unfavorable for the debtor state, even if it avoids defeat. In this analysis, the state uses war debt to smooth expected consumption intertemporally in response to temporary war spending, and the state also uses contingent debt servicing to insure realized consumption against the risk associated with the material consequences of the war. An important innovation in the analysis is to treat the equilibrium amount of war spending, the state's resulting probability of avoiding defeat, as well as the equilibrium amount of borrowing as a set of endogenous variables to be determined simultaneously. 相似文献

This paper gives a new organization of the theoretical results of the Generalized Transportation Problem with capacity constraints. A graph-theoretic approach is utilized to define the basis as a one-forest consisting of one-trees (a tree with an extra edge). Algorithmic development of the pivot-step is presented by the representation of a two-tree (a tree with two extra edges). Constructive procedures and proofs leading to an efficient computer code are provided. The basic definition of an operator theory which leads to the discussion of various operators is also given. In later papers we will present additional results on the operator theory for the generalized transportation problem based on the results in the present paper. 相似文献
