Quantifying the performance effects of idle time utilization in multiserver systems

In many practical multiserver queueing systems, servers not only serve randomly arriving customers but also work on the secondary jobs with infinite backlog during their idle time. In this paper, we propose a c‐server model with a two‐threshold policy, denoted by (e d), to evaluate the performance of this class of systems. With such a policy, when the number of idle servers has reached d (<c), then e (<d) idle agents will process secondary jobs. These e servers keep working on the secondary jobs until they find waiting customers exist in the system at a secondary job completion instant. Using the matrix analytic method, we obtain the stationary performance measures for evaluating different (e, d) policies. © 2006 Wiley Periodicals, Inc. Naval Research Logistics, 2007.     

Constrained minimax optimization of continuous search efforts for the detection of a stationary target

Analytical resolution of search theory problems, as formalized by B.O. Koopman, may be applied with some model extension to various resource management issues. However, a fundamental prerequisite is the knowledge of the prior target density. Though this assumption has the definite advantage of simplicity, its drawback is clearly that target reactivity is not taken into account. As a preliminary step towards reactive target study stands the problem of resource planning under a min–max game context. This paper is related to Nakai's work about the game planning of resources for the detection of a stationary target. However, this initial problem is extended by adding new and more general constraints, allowing a more realistic modeling of the target and searcher behaviors. © 2007 Wiley Periodicals, Inc.

Probabilistic solution and bounds for serial inventory systems with discounted and average costs

We consider the infinite horizon serial inventory system with both average cost and discounted cost criteria. The optimal echelon base‐stock levels are obtained in terms of only probability distributions of leadtime demands. This analysis yields a novel approach for developing bounds and heuristics for optimal inventory control polices. In addition to deriving the known bounds in literature, we develop several new upper bounds for both average cost and discounted cost models. Numerical studies show that the bounds and heuristic are very close to optimal.© 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

用毁伤概率指标优化二点源诱饵系统布阵

两点源诱偏系统是应用有源干扰的方式,利用反辐射导弹(ARM)本身的缺陷来对反辐射导弹的导引头进行干扰,从而达到保护主战雷达目的的一种有源干扰系统。主要从反辐射导弹的基本原理和有源诱偏的概念入手,对两点源诱偏系统进行理论推导、数学建模、布站设想,后引入毁伤概率指标对各种布站方式进行分类、仿真,对每一种仿真结果进行分析、评估,再把各种分析结果加以比较,从中找出最佳的布站方式。最后利用以上的分析结果,得出几点有用的结论。

论心理健康教育的人本价值

心理健康教育无疑具有重要的人本价值。从历史发展看,心理健康教育就是沿着以人为本的方向演进;人作为心理健康教育价值的承载者,其心理的复杂性决定着心理健康教育的人本向度;心理健康教育的人本价值则体现在从个体全面发展到民族素质的综合提高上;只有树立起以人为本的心理健康教育观,方能真正实现其人本价值。
