Performance Approximation and Design of Pick-and-Pass Order Picking Systems

Yu, M.; Koster, M.B.M. de - Erasmus Research Institute of Management (ERIM), ERIM … - 2007

In this paper, we discuss an approximation method based on G/G/m queuing network modeling using Whittâ€™s (1983 …) queuing network analyzer to analyze pick-and-pass order picking systems. The objective of this approximation method is to … approximation method based on G/G/m queuing network modeling using Whitt’s (1983) queuing network analyzer to analyze pick …

Capacity Planning for Virtualized Servers

Bichler, Martin; Setzer, Thomas; Speitkamp, Benjamin - 2007

Today's data centres offer many different IT services mostly hosted on dedicated physical servers. Virtualization provides a technical means for server consolidation leading to increased server utilization. The term refers to the abstraction of computing resources across many aspects of...

A Queuing and Statistical Analysis of Freeway Bottleneck Formation

Das, Shantanu; Levinson, David Matthew - 2007

A modified approach to treat traffic flow parameters (flow, density and speed) has been introduced in this paper. A queuing analysis has been conducted on traffic flow data on Interstate 94 in the Minneapolis-St. Paul metro area. A methodology has been developed to calibrate loop detector count...

Locating Emergency Services With Priority Rules : The Priority Queuing Covering Location Problem

Silva, Francisco José Ferreira; Serra, Daniel - 2007

Previous emergency service covering models consider all the calls to be of the same importance and impose the same waiting time constraints independently of the service's priority. This type of constraint is clearly inappropriate in many contexts. For example, in urban medical emergency...

Cost Sharing in a Job Scheduling Problem

Mishra, Debasis; Rangarajan, Bharath - 2007

A set of jobs need to be served by a server which can serve only one job at a time. Jobs have processing times and incur waiting costs (linear in their waiting time). The jobs share their costs through compensation using monetary transfers. In the first part, we provide an axiomatic...

Using G/G/m-models for multi-server and mainframe capacity planning

Müller-Clostermann, Bruno - 2007

Results from classic queueing theory are shown to be useful for capacity planning of largescale multi-server systems. In the field of mainframe systems on-line monitoring and dynamic workload management care for the fulfilment of short-term performance goals with respect to service class...

Queueing problems with two parallel servers

Chun, Youngsub (contributor); Heo, Eun Jeong (contributor) - 2007

A group of agents are waiting for their job to be processed in a facility. We assume that each agent needs the same amount of processing time and incurs waiting costs. The facility has two parallel servers, being able to serve two agents at a time. We are interested in finding the order to serve...
