Two-agent scheduling with linear resource-dependent processing times

This paper considers a two-agent scheduling problem with linear resource-dependent processing times, in which each agent has a set of jobs that compete with that of the other agent for the use of a common processing machine, and each agent aims to minimize the weighted number of its tardy jobs. To meet the due date requirements of the jobs of the two agents, additional amounts of a common resource, which may be in discrete or continuous quantities, can be allocated to the processing of the jobs to compress their processing durations. The actual processing time of a job is a linear function of the amount of the resource allocated to it. The objective is to determine the optimal job sequence and resource allocation strategy so as to minimize the weighted number of tardy jobs of one agent, while keeping the weighted number of tardy jobs of the other agent, and the total resource consumption cost within their respective predetermined limits. It is shown that the problem is -hard in the ordinary sense, and there does not exist a polynomial-time approximation algorithm with performance ratio unless ; however it admits a relaxed fully polynomial time approximation scheme. A proximal bundle algorithm based on Lagrangian relaxation is also presented to solve the problem approximately. To speed up convergence and produce sharp bounds, enhancement strategies including the design of a Tabu search algorithm and integration of a Lagrangian recovery heuristic into the algorithm are devised. Extensive numerical studies are conducted to assess the effectiveness and efficiency of the proposed algorithms.

略论清末北方军事集团的军事教育及其影响

清末北方军事集团,前后有两个界定：一是洋务运动时期以李鸿章为首的“北洋海军军事集团”;二是新政时期至北洋前期以袁世凯为首的“新建陆军军事集团”。二者前后并没有直系的承接关系。但他们在创办军事教育方面都做出有目共睹的成就,促进了中国教育,尤其是军事科技教育的现代化发展,对中国近代社会产生重要影响。同时也应该看到,由于军事集团创办并掌握教育主导权,导致教育的集团化和教育的私人化,形成中国军队派系对立,是最终促成近代中国军阀割据局面出现的重要因素。     

抗震救灾斗争对执行多样化军事任务的启示

执行多样化军事任务事关国家安全和发展利益,紧系人民生命财产安全,要求我们必须有高度的政治责任意识;执行多样化军事任务参与力量多、协作任务重、工作范围广,要求我们必须建立健全联合高效的统一指挥机制;执行多样化军事任务往往事发突然,通讯交通受阻、信息采集难度大、新闻宣传制约因素多,要求我们必须注意信息掌握与管控;执行多样化军事任务艰巨繁重,任务转换节奏快,专业素质要求高,要求我们平时必须加强非战争军事行动的针对性训练;执行多样化军事任务条件艰苦、环境恶劣,不仅要连续作战,而且随时面临生命危险,要求我们必须大力培育部队的战斗精神;执行多样化军事任务对后勤补给、装备保障有着特殊要求,我们必须不断加强执行多样化军事任务的各项保障建设。

浅论应急作战背景下的网络破袭战

现代战争是体系与体系的对抗,随着战场上的传感器网络、指挥控制网络、通信网络和火力打击网络的有机联结,并组成一个统一的作战体系。体系破袭已经成为敌对双方首要采取的作战方式。其作战目的明确,就是削弱对方的信息可达度和信息优裕度,使其作战能力始终处于平台中心区域而无法达到信息中心区域。应急作战背景下,可将网络破袭战作为对敌体系破袭的重要手段,以未来作战对手高度依赖的信息网络系统为打击重心,“断网毁链”,削弱敌整体作战能力。     

Approximation schemes for single‐machine scheduling with a fixed maintenance activity to minimize the total amount of late work

We consider the problem of scheduling n independent and simultaneously available jobs without preemption on a single machine, where the machine has a fixed maintenance activity. The objective is to find the optimal job sequence to minimize the total amount of late work, where the late work of a job is the amount of processing of the job that is performed after its due date. We first discuss the approximability of the problem. We then develop two pseudo‐polynomial dynamic programming algorithms and a fully polynomial‐time approximation scheme for the problem. Finally, we conduct extensive numerical studies to evaluate the performance of the proposed algorithms. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 172–183, 2016
