卡尔曼滤波在坦克目标状态估计中的应用

分析了现有机动目标数学模型及其卡尔曼滤波算法,并用数字信号处理器(DSP)对一个实际算法进行了实验.实验结果表明目标机动性能的提高将使坦克火控系统由于采用现行目标运动模型而产生较大的误差,因此,在火控系统中采用其他模型,如自适应模型等,势在必行.同时,对于跟踪精度高、实时计算量大的卡尔曼滤波算法,应用DSP技术实现具有良好的发展前景.     

Approximation results for min‐max path cover problems in vehicle routing

This article studies a min‐max path cover problem, which is to determine a set of paths for k capacitated vehicles to service all the customers in a given weighted graph so that the largest path cost is minimized. The problem has wide applications in vehicle routing, especially when the minimization of the latest service completion time is a critical performance measure. We have analyzed four typical variants of this problem, where the vehicles have either unlimited or limited capacities, and they start from either a given depot or any depot of a given depot set. We have developed approximation algorithms for these four variants, which achieve approximation ratios of max{3 ‐ 2/k,2}, 5, max{5 ‐ 2/k,4}, and 7, respectively. We have also analyzed the approximation hardness of these variants by showing that, unless P = NP , it is impossible for them to achieve approximation ratios less than 4/3, 3/2, 3/2, and 2, respectively. We have further extended the techniques and results developed for this problem to other min‐max vehicle routing problems.© 2010 Wiley Periodicals, Inc. Naval Research Logistics, 2010     

海战场态势分析作战想定生成技术研究

态势分析是战场态势监视系统的一项关键技术。在态势分析研究中,需要利用某些作战想定来检验态势分析算法的效果。本文针对该问题,研究了作战想定生成技术,利用该技术为海战场态势分析仿真系统生成某些剧情,并输入想定数据。首先建立了海战场环境下单目标、编队目标的运动模型,生成相关的群体态势参数,并基于此建立了海战场态势分析想定平台,在此平台上生成了一个红蓝双方对抗的想定,并用其验证了一个态势分析的海战场机动目标功能合群算法。

Performance analysis of queue length monitoring of M/G/1 systems

This study investigates the statistical process control application for monitoring queue length data in M/G/1 systems. Specifically, we studied the average run length (ARL) characteristics of two different control charts for detecting changes in system utilization. First, the nL chart monitors the sums of successive queue length samples by subgrouping individual observations with sample size n. Next is the individual chart with a warning zone whose control scheme is specified by two pairs of parameters, (upper control limit, d_u) and (lower control limit, d_l), as proposed by Bhat and Rao (Oper Res 20 (1972) 955–966). We will present approaches to calculate ARL for the two types of control charts using the Markov chain formulation and also investigate the effects of parameters of the control charts to provide useful design guidelines for better performance. Extensive numerical results are included for illustration. © 2011 Wiley Periodicals, Inc. Naval Research Logistics, 2011
