基于动平衡状态理论的非线性系统设计方法

基于动平衡状态理论的非线性设计方法是一种建立在控制系统动平衡状态渐近稳定概念上的新的设计方法.首先设计控制律使系统的动平衡状态按期望的方式运动,然后按某一指标设计系统,使其状态按最佳方式向动平衡状态收敛.使用此方法对非线性跟踪问题进行设计,设计过程简单清楚,仿真结果正确,并能更深刻反映动平衡状态的含义.

Scheduling parallel machines with inclusive processing set restrictions

We consider the problem of assigning a set of jobs to different parallel machines of the same processing speed, where each job is compatible to only a subset of those machines. The machines can be linearly ordered such that a higher‐indexed machine can process all those jobs that a lower‐indexed machine can process. The objective is to minimize the makespan of the schedule. This problem is motivated by industrial applications such as cargo handling by cranes with nonidentical weight capacities, computer processor scheduling with memory constraints, and grades of service provision by parallel servers. We develop an efficient algorithm for this problem with a worst‐case performance ratio of + ε, where ε is a positive constant which may be set arbitrarily close to zero. We also present a polynomial time approximation scheme for this problem, which answers an open question in the literature. © 2008 Wiley Periodicals, Inc. Naval Research Logistics, 2008     

An approximate dynamic programing approach to the development of heuristics for the scheduling of impatient jobs in a clearing system

A single server is faced with a collection of jobs of varying duration and urgency. Each job has a random lifetime during which it is available for nonpreemptive service. Should a job's lifetime expire before its service begins then it is lost from the system unserved. The goal is to schedule the jobs for service to maximize the expected number served to completion. Two heuristics have been proposed in the literature. One (labeled π^S) operates a static priority among the job classes and works well in a “no premature job loss” limit, whereas the second (π^M) is a myopic heuristic which works well when lifetimes are short. Both can exhibit poor performance for problems at some distance from the regimes for which they were designed. We develop a robustly good heuristic by an approximative approach to the application of a policy improvement step to the asymptotically optimal heuristic π^S, in which we use a fluid model to obtain an approximation for the value function of π^S. The performance of the proposed heuristic is investigated in an extensive numerical study. © 2010 Wiley Periodicals, Inc. Naval Research Logistics 2010

智能化是现代航空弹药需求与指挥控制系统的发展趋势,如何进行合理快速地调拨航空弹药是系统设计过程中的关键任务之一。为此,提出了依据目标对航空弹药进行选择的策略,利用蚁群算法对战斗目标进行聚类分析,对各类目标进行模糊综合评判,从而确定装备出动方案,依据弹药与装备的关系,对满足既定保障度的弹药需求量建立模型,并计算出满足既定保障度的弹药供应量,为战前对战场态势预估,实现弹药战时及时准确调拨,为作战弹药准备提供依据。     

球形破片侵彻明胶运动模型及破片参数敏感性分析

为揭示球形破片对人体组织致伤机理,以明胶作为人体组织的替代物,基于动态空腔膨胀理论,考虑球形破片未完全侵入阶段的速度衰减,建立了球形破片侵彻明胶的分段运动理论模型,研究了球形破片侵彻明胶的运动规律。通过钢球和钨球侵彻明胶的实验验证了模型的正确性,求解了模型中的最优阻力系数。分析了理论计算过程中的误差来源,并推导得到了无量纲侵彻深度的表达式。利用Sobol′法进行了球形破片参数(直径、密度和速度)对侵彻深度影响的敏感性分析。结果表明：运动模型能够较好地模拟球形破片的运动规律;低密度的球形破片在未完全侵入阶段的速度衰减不能忽略;球形破片参数对侵彻深度影响的敏感性由高到低依次是速度、密度和直径。
