为降低消费者租借云计算系统资源的开销,提出了成本约束的内存预留随机整数线性规划模型及方法。结合预留计划和按需计划的内存资源价格,设计包含成本及资源总量约束条件的随机开销函数,并以函数期望值最小化为目标,基于内存消耗量概率分布求出优化的内存预留量。试验表明,消费者利用该方法租借资源的开销比利用预留计划、按需计划及同类方法租借资源的开销更小。 相似文献

To meet customer demand, delivery companies are offering an increasing number of time‐definite services. In this article, we examine the strategic design of delivery networks which can efficiently provide these services. Because of the high cost of direct connections, we focus on tree‐structured networks. As it may not be possible to identify a tree‐structured network that satisfies all of the delivery guarantees, we allow these guarantees to be violated but seek to minimize the sum of the violations. We establish the complexity of the problem and exploit an empirically identified solution structure to create new neighborhoods which improve solution values over more general neighborhood structures. © 2008 Wiley Periodicals, Inc.

This study introduces one modeling methodology that describes a broad range of multiple stage production planning issues, including multiple limited resources with setup times and joint fixed cost relationships. An existing production system is modeled in this fashion, creating a new set of 1350 highly generalized benchmark problems. A computational study is conducted with the 1350 benchmark problems introduced in this paper and 2100 benchmark problems, with more restrictive assumptions, from the existing literature. The relative merits of a decomposition‐based algorithm and a neighborhood search technique known as NIPPA, or the Non‐sequential Incremental Part Period Algorithm, are assessed. NIPPA is generally the more successful of the two techniques, although there are specific instances in which the decomposition‐based algorithm displayed a distinct advantage. © 2005 Wiley Periodicals, Inc.

高层建筑火灾具有火灾蔓延途径多、火灾荷载大、扑救难度大等特点,易造成群死群伤的严重后果。在火灾扑救中,主要有举高消防车的高度、出警速度极限、人员疏散与战斗进攻路线、战斗员体能和火场供水等五个方面的限制因素。从实战出发,提出了增强高层建筑火灾灭火救援能力应采取的措施。 相似文献

Minimizing the makespan in open‐shop scheduling problems with a convex resource consumption function
We consider open‐shop scheduling problems where operation‐processing times are a convex decreasing function of a common limited nonrenewable resource. The scheduler's objective is to determine the optimal job sequence on each machine and the optimal resource allocation for each operation in order to minimize the makespan. We prove that this problem is NP‐hard, but for the special case of the two‐machine problem we provide an efficient optimization algorithm. We also provide a fully polynomial approximation scheme for solving the preemptive case. © 2006 Wiley Periodicals, Inc. Naval Research Logistics, 2006 相似文献
