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

潜艇规避被动声纳浮标阵方法及期望驶离时间 总被引:2,自引:0,他引:2
基于对反潜巡逻机布放被动声纳浮标阵的研究,对方形阵的布放建立了模型。利用该模型研究了我潜艇规避被动浮标声纳阵的方法。通过计算,得出潜艇驶离被动声纳浮标阵搜索范围的期望时间,用选取的声纳浮标阵间距和潜艇规避速度对结果进行分析,为潜艇的下一步行动提供辅助决策。 相似文献

Submarine berthing plans reserve mooring locations for inbound U.S. Navy nuclear submarines prior to their port entrance. Once in port, submarines may be shifted to different berthing locations to allow them to better receive services they require or to make way for other shifted vessels. However, submarine berth shifting is expensive, labor intensive, and potentially hazardous. This article presents an optimization model for submarine berth planning and demonstrates it with Naval Submarine Base, San Diego. After a berthing plan has been approved and published, changed requests for services, delays, and early arrival of inbound submarines are routine events, requiring frequent revisions. To encourage trust in the planning process, the effect on the solution of revisions in the input is kept small by incorporating a persistence incentive in the optimization model. © 1997 John Wiley & Sons, Inc.

The US Navy's audacious Maritime Strategy of the 1980s is often credited with acting as a key catalyst to the demise of the USSR. In assessing the role of strategic missile submarine “bastions” in the country's overall military strategy, the authors are skeptical of the above thesis, explaining that Moscow actually viewed deployments of Tomahawk land-attack cruise missiles on to US submarines (versus direct threats against the Soviet Navy itself) as the most alarming threat. The authors concede that the arms race played a role in the collapse of the USSR, but deny a direct connection with Soviet naval development citing the relatively minor naval proportion of overall defense spending. For the difficulties facing the fleet at the end of the Cold War, they instead blame deep systemic problems internal to the Soviet Navy. 相似文献
