Machine scheduling with an availability constraint and job delivery coordination

In this paper we study the scheduling problem that considers both production and job delivery at the same time with machine availability considerations. Only one vehicle is available to deliver jobs in a fixed transportation time to a distribution center. The vehicle can load at most K jobs as a delivery batch in one shipment due to the vehicle capacity constraint. The objective is to minimize the arrival time of the last delivery batch to the distribution center. Since machines may not always be available over the production period in real life due to preventive maintenance, we incorporate machine availability into the models. Three scenarios of the problem are studied. For the problem in which the jobs are processed on a single machine and the jobs interrupted by the unavailable machine interval are resumable, we provide a polynomial algorithm to solve the problem optimally. For the problem in which the jobs are processed on a single machine and the interrupted jobs are nonresumable, we first show that the problem is NP‐hard. We then propose a heuristic with a worst‐case error bound of 1/2 and show that the bound is tight. For the problem in which the jobs are processed on either one of two parallel machines, where only one machine has an unavailable interval and the interrupted jobs are resumable, we propose a heuristic with a worst‐case error bound of 2/3. © 2006 Wiley Periodicals, Inc.

论武器装备的劣势对志愿军作战的影响

在革命战争年代,中国共产党领导的人民军队以劣势装备先后打败了装备精良的日本军队和国民党军队,建立了新中国.但抗美援朝战争爆发后,中国人民志愿军在面对美国军队时发现:以往很多行之有效的经验不灵了.究其原因,主要是美军对志愿军在武器装备方面占有绝对优势,这种优势是日军对八路军、新四军的优势和国民党军对人民解放军的优势远远不能比拟的.这一特点深刻影响了志愿军的作战行动,改变了人民军队在以往战争中形成的很多作战原则,也深刻影响了抗美援朝战争的结局.     

史迪威与杜聿明在缅甸战场上的恩怨纠葛(下)

五、同举平满纳会战,史迪威与杜聿明两人重归于好 史迪威对于我想给他讲述《将相和》故事的用心,虽然已表示理解,并嘱我放心他同杜聿明的关系,但在3月31日他到重庆向蒋介石汇报时,仍然告了杜聿明的"状",指责杜聿明和廖耀湘蔑视他的权威,不听他的命令,遂使同古攻势夭折,缅甸战局逆转,请求处分杜、廖二人.同时他还向蒋介石说他要辞职回国,不回缅甸了.

青马军制考论——以兵源、军官和训练为考察中心

青海回族军阀是一支活跃在西北政坛上的地方割据势力。清末以来西北动荡而复杂多变的政局、雄厚的封建地主阶级实力的存在、复杂的民族宗教关系、社会经济衰落造成的农民破产和游离以及青海回族军阀三代的军事积淀,为其割据青海局面的形成创造了条件。而在青海回族军阀体系中,其军事制度扮演着至关重要的角色,只有通过对军制的考察,方能从微观上探讨其军事实力消长的原由。本文拟以兵源、军官成分及训练为核心,对青海回族军阀的军事制度进行了较为深入的剖析及研究,以期引起学术界对其军事制度的探讨和研究。     

Properties of the geometric and related processes

Some properties of the geometric process are studied along with those of a related process which we propose to call the α‐series process. It is shown that the expected number of counts at an arbitrary time does not exist for the decreasing geometric process. The decreasing version of the α‐series process does have a finite expected number of counts, under certain conditions. This process also has the same advantages of tractability as the geometric process; it exhibits some properties which may make it a useful complement to the increasing geometric process. In addition, it may be fit to observed data as easily as the geometric process. Applications in reliability and stochastic scheduling are considered in order to demonstrate the versatility of the alternative model. © 2005 Wiley Periodicals, Inc. Naval Research Logistics, 2005
