为增强航路规划算法的适用性,充分考虑潜艇面临的动态威胁,建立并求解了基于多目标动态威胁的潜艇航路规划模型.首先,介绍了微分对策的基本理论,指出其在处理航路规划问题方面的优越性;其次,引入了基于单目标威胁的航路规划模型,并采用微分对策对其进行了描述和求解;最后,在单目标威胁模型的基础上,推导了基于多目标动态威胁的潜艇航路规划模型,建立了对策的状态变量、控制变量及其约束、状态方程与微分对策模型,并给出了其微分对策的系统解.数值求解结果表明:该算法可较好地解决动态对抗问题,只需确定界栅和最优策略即可,同时该航路规划算法简便易行,具有较强的适用性. 相似文献

The aim of this paper is to investigate the determinants of international arms transfers in a gravity model framework. By distinguishing between the decision to export arms (extensive margin) and the value of the arms exported (intensive margin), while also considering its interdependence, is what differentiates this paper from previous research. A theoretically justified gravity model of trade augmented with political and security motives is estimated using a two-stage panel data approach for 104 exporting countries over the period from 1950 to 2007. In addition to the usual gravity variables related to the economic mass of the trading countries and the trade cost factors, the model is extended with political and security factors. The level of democracy in both trading partners, political differences between trading partners and voting similarity with the United States in the UN General Assembly of the countries engaged in trade are the main political factors, whereas the existence of conflicts, military pacts, and embargoes are taken as security motives. The key result indicates that both political and security motives are an important determinant of an arms trade, but their effects on the extensive margin of exports (the decision to order a transfer) differs from their effect on the intensive margin (average value of exports). Moreover, the relative importance of the factors under study has changed since 1989. In the post-cold war period, countries that are less democratic are more likely to export arms, military pacts are less relevant and embargoes play a role. 相似文献

The paper draws on the demand for arms imports model of Levine and Smith (1995, 1997) using stochastic processes of the birth-death type in steady state. It assumes two antagonistic regional players engaged in an armaments race satisfying their demand for military hardware through imports from the international market. The paper examines the effects that arms imports have on the military balance between the two recipient countries. It constructs a state space of possible outcomes in terms of the military balance/imbalance between the two countries involved. A new variable is introduced which tries to encapsulate the absolute difference in their respective security functions at any moment in time. This variable affects the transition from one state of affairs to the other. 相似文献

This study analyzes the determinants of arms production in 15 countries using annual panel data from 1997 to 2002. The results suggest that real GDP per capita, military expenditures, arms exports, and arms imports are positively related to arms production. 相似文献
