基于非对称balls-into-bins的高效平衡负载分配模型

在大规模数据中心和P2P覆盖网络等复杂网络负载平衡分配中,前人提出了多种多样的负载分配方法,但许多方法为了达到更好的平衡负载指标,追求越来越复杂的算法,使得时间复杂度和算法复杂度很难控制在合理的范围之内。本文在研究了经典balls-into-bins、Azar balls-into-bins和balls into non-uniformbins等模型的基础上,提出了一种新颖高效的非对称balls-into-bins平衡负载分配模型,该模型具有异构的balls、异构的bins,以及不同的bin选择概率,能以很高的概率将最大负载均衡地控制在合理的范围内,通信负载很小,且具有很好的可扩展性,通过拓展,该模型在负载平衡的诸多领域都将有广阔的应用空间。     

What you should know about simulation and derivatives

Derivatives (or gradients) are important for both sensitivity analysis and optimization, and in simulation models, these can often be estimated efficiently using various methods other than brute‐force finite differences. This article briefly summarizes the main approaches and discusses areas in which the approaches can most fruitfully be applied: queueing, inventory, and finance. In finance, the focus is on derivatives of another sort. © 2008 Wiley Periodicals, Inc. Naval Research Logistics, 2008     

基于平衡计分卡的武器装备维修绩效评价指标体系构建

武器装备维修是武器装备维修保障的重要内容,加强装备维修绩效评价,建立科学规范的绩效评价指标体系,对深入推进装备维修工作健康发展将发挥积极作用。以平衡计分卡为研究手段,运用"5M1E"分析法,从一个内核和四个维度出发,分析武器装备维修绩效评价的影响因素,据此建立评价指标体系,并应用于装备维修管理实践,为有效提高装备维修保障效益提供有益借鉴。     

A note on the financial condition of defense contractors

In recent years, there have been several changes in the weapon‐system acquisition market which have the potential to negatively impact the financial condition of defense contractors. This study evaluates the financial health of defense firms vis‐a‐vis nondefense firms using a fiscal distress identification model developed by E.I. Altman. We conclude that the financial condition of defense firms has deteriorated but the deterioration is the same as experienced by nondefense firms.     

一种能量高效和均衡的无线传感器网络分簇数据融合算法

在无线传感器网络中,如果传感器节点之间的能耗不均衡,一些能耗进度较快的节点会过快失效,继而导致网络过早无法正常工作。为了解决分簇无线传感器网络在数据收集过程中所存在的节点之间能耗不均衡问题,提出了一种新的分簇数据融合算法。该算法将网络划分为大小不等的栅格,并根据剩余能量使簇首分别在每个栅格的节点中轮转。簇首消耗的能量越多,其所在的栅格也越大,栅格内有更多节点参与簇首的轮换以分担能量负载。通过该方式,算法能够提高节点的能耗均衡程度。另外,考虑到无线传感器网络的能量受限,算法还采取了一系列措施以节约能量。仿真实验结果表明,算法在能量使用效率、网络生命周期以及能耗均衡程度三个方面都具有较好的性能。
