On‐line algorithms for minimizing makespan on batch processing machines

We consider problem of scheduling jobs on‐line on batch processing machines with dynamic job arrivals to minimize makespan. A batch machine can handle up to B jobs simultaneously. The jobs that are processed together from a batch, and all jobs in a batch start and complete at the same time. The processing time of a batch is given by the longest processing time of any job in the batch. Each job becomes available at its arrival time, which is unknown in advance, and its processing time becomes known upon its arrival. In the first part of this paper, we address the single batch processing machine scheduling problem. First we deal with two variants: the unbounded model where B is sufficiently large and the bounded model where jobs have two distinct arrival times. For both variants, we provide on‐line algorithms with worst‐case ratio (the inverse of the Golden ratio) and prove that these results are the best possible. Furthermore, we generalize our algorithms to the general case and show a worst‐case ratio of 2. We then consider the unbounded case for parallel batch processing machine scheduling. Lower bound are given, and two on‐line algorithms are presented. © 2001 John Wiley & Sons, Inc. Naval Research Logistics 48: 241–258, 2001

多媒体教学与政治理论教员的发展走向

多媒体教学强大的替代作用使人们对教员的地位和作用产生怀疑。政治理论教员应该选取正确的发展思路 ,使自身的言传身教与多媒体教学相得益彰。在运用多媒体教学的过程中 ,政治理论教员应该努力做到 :突出授课风格的个性化 ;实现道德、人格的魅力化 ;由理论灌输式向“实话实说”式、“焦点访谈”式转变 ;由知识传输型向学者型、专家型、创新型转变 ;由授业者向播火者转变 ;激发学员的非智力因素 ,促进学员成才的多样化。

An (s,S) model for inventory with exponential lifetimes and renewal demands

Inventory control of products with finite lifetimes is important in many modern business organizations. It has been an important and difficult research subject. Here, we study the (s, S) continuous review model for items with an exponential random lifetime and a general renewal demand process through a Markov process. We derive a fundamental rate conservation theorem and show that all the other system performance measures can be obtained easily through the expected reorder cycle length. This leads to a simple expression for the total expected long run cost rate function in terms of the expected reorder cycle length. Subsequently, we derive formulas for computing the expected cycle lengths for the general renewal demand as well as for a large class of demands characterized by the phase type interdemand time distribution. We show analytically when the cost as a function of the reorder level is monotone, concave, or convex. We also show analytically that, depending on the behavior of the expected reorder cycle, the cost as a function of the order‐up level is either monotone increasing or unimodal. These analytical properties enable us to understand the problem and make the subsequent numerical optimization much easier. Numerical studies confirm and illustrate some of the analytical properties. The results also demonstrate the impact of various parameters on the optimal policy and the cost. © 1999 John Wiley & Sons, Inc. Naval Research Logistics 46: 39–56, 1999     

弹炮结合武器系统作战效能评估

弹炮结合系统是一种有效的防空武器系统,但以往对该武器系统的作战效能评估存在两方面不足:一是较少考虑攻防双方的对抗以及环境对作战效能的影响,使得出的指标可信度降低;二是不同国度、类别、型号的武器系统没有构建统一的价值可比空间,使获得的指标缺乏横向可比性.为此利用灰色关联综合优化法有关原理,给出弹炮结合防空系统作战效能的评价指标体系,确立了相关的隶属函数,进而通过六种弹炮结合防空系统作战效能的优劣排序,验证了该方法有效可行,初步解决了上述问题.
