This paper proposes an integrated network design model for a post-distribution cross-docking strategy, comprising multi product production facilities with shared production resources, capacitated cross docks with setup cost and customer zones with time windows constraints. The model is dynamic in terms of time-varying uncertain demands, whereas uncertainty is expressed with scenario approach an...

Received (received date) Revised (revised date) Communicated by (Name of Editor) ABSTRACT In this paper we present a performance model for a constant service time, globally synchronized multistage interconnection network that is an improvement on earlier work in this eld. The events at the network input are assumed to have a geometric distribution in time. As the events are combined within the ...

Presents a compact optimal algorithm maximize equity allocation across blood types ethnic groups. Analyses discusses implemented policies improve kidney the USA. Inequities times donor transplantation have r...

Workloads for web applications can change rapidly. When the change is an increase in customers, a common adaptive approach to maintain SLAs is elasticity, the on-demand allocation of computing resources. However, application-level denial-of-service (DoS) attacks can also cause changes in workload, and require an entirely different response. These two issues are often addressed separately (in bo...

The primary goal of future cellular mobile communication networks is to provide efficient and cost effective services to mobile users under all environments. The major issues that affects the quality of service and performance in wireless communications systems is scarcity of resources. Hence, efficient resource allocation is prime concern in order to improve the performance of cellular network...

ABSTRACT We tackle the problem of designing revenue maximizing auctions in the Bayesian framework, when bidders not only have private valuations but also private budgets. We consider the setting of selling divisible goods to multiple agents each with linear utilities, but agents cannot pay beyond their budget. We focus on the case when the auctioneer can check that bidders do not over-report th...

In this paper, we propose a novel bandwidth allocation scheme that will guarantee quality-of-service (QoS) support in the downlink (DL) of a LTE-A system. The proposed scheme is developed based on a queuing model that links important performance metrics of DL service flows of LTE-A systems to a set of tunable parameters. Based on the outcome of the results of the queuing model, the performance ...

The end-to-end delay is one of the most critical and fundamental issues for wireless sensor networks. Many applications of sensor networks require an end-to-end delay guarantee for time sensitive data. However, the end-to-end delay is difficult to bound for event-driven sensor networks, where nodes generate and propagate data only when an event of interest occurs, thereby producing unpredictabl...

Truck and shovel are the most common raw material transportation system used in the cement quarry operations. One of the major challenges associated with the cement quarry operations is the efficient allocation of truck and shovel to the mining faces. In order to minimize the truck and shovel operating cost, subject to quantity and quality constraints, the mixed integer linear programing (MILP)...

In this paper, we propose a novel scheduling scheme that will provide quality-of-service (QoS) support in the downlink (DL) of a WiMAX system. The proposed Subchannel mapping Scheduling Algorithm completely exploits the physical layer properties of the Orthogonal Frequency Division Multiple Access (OFDMA) in order to improve the throughput of the WiMAX network at the same time improving the QoS...
