有限维修能力下作战单元时变可用度评估模型

针对作战单元任务期内备件需求随任务阶段动态变化的现实情况,考虑作战单元因携行维修能力有限而导致可修件具有一定报废概率的影响,通过引入报废因子,建立两级保障体制下,故障件具有一定报废概率且不考虑外部补给的作战单元时变可用度评估模型。采用Extend Sim仿真软件进行计算,根据仿真值进行参数拟合得到模型中报废因子的近似解析表达形式。研究表明,报废因子能够适应不同的可靠性维修性参数值,模型具有较强的适应性。该模型有效解决了备件非平衡状态下的装备时变可用度评估问题,可为装备管理人员制定合理的保障方案提供支撑。

A model for geographically distributed combat interactions of swarming naval and air forces

This article describes the Distributed Interaction Campaign Model (DICM), an exploratory campaign analysis tool and asset allocation decision‐aid for managing geographically distributed and swarming naval and air forces. The model is capable of fast operation, while accounting for uncertainty in an opponent's plan. It is intended for use by commanders and analysts who have limited time for model runs, or a finite budget. The model is purpose‐built for the Pentagon's Office of Net Assessment, and supports analysis of the following questions: What happens when swarms of geographically distributed naval and air forces engage each other and what are the key elements of the opponents’ force to attack? Are there changes to force structure that make a force more effective, and what impacts will disruptions in enemy command and control and wide‐area surveillance have? Which insights are to be gained by fast exploratory mathematical/computational campaign analysis to augment and replace expensive and time‐consuming simulations? An illustrative example of model use is described in a simple test scenario. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 562–576, 2016

Analysis of artillery shoot‐and‐scoot tactics

Firing multiple artillery rounds from the same location has two main benefits: a high rate of fire at the enemy and improved accuracy as the shooter's aim adjusts to previous rounds. However, firing repeatedly from the same location carries significant risk that the enemy will detect the artillery's location. Therefore, the shooter may periodically move locations to avoid counter‐battery fire. This maneuver is known as the shoot‐and‐scoot tactic. This article analyzes the shoot‐and‐scoot tactic for a time‐critical mission using Markov models. We compute optimal move policies and develop heuristics for more complex and realistic settings. Spending a reasonable amount of time firing multiple shots from the same location is often preferable to moving immediately after firing an initial salvo. Moving frequently reduces risk to the artillery, but also limits the artillery's ability to inflict damage on the enemy.     

一种改进遗传算法在UCAV快速航迹规划中的应用

针对无人作战飞机(Unmanned Combat Aerial Vehicle,UCAV)航迹规划约束条件复杂、不确定因素多、实时性要求高的特点,提出了一种基于Voronoi图和改进遗传算法的快速航迹规划方法。该方法采取分层航迹规划的思想,首先根据Voronoi图生成初始航迹,并综合考虑约束条件,赋予各条航迹相应的权值;然后应用改进的遗传算法在生成的航迹空间中寻优,最终得到满意的航迹。该算法利用多处理机并行计算技术对传统遗传算法进行改进,大大缩短寻优时间。仿真结果表明基于Voronoi图和改进遗传算法的航迹规划提高了实时性,增强了UCAV的动态战场适应能力和突发威胁应对能力。
