Resource allocation in the Grid. A market engineering approach
Schnizler, Björn - 2007
The Grid provides access to distributed computational capabilities such as processors or storage space. One of the key problems is deciding which jobs are to be allocated to which resources at what time. In this context, the use of market mechanisms is a promising approach to solve these...

Market-Based Scheduling in Distributed Computing Systems
Stößer, Jochen - 2009
In verteilten Rechensystemen (bspw. im Cluster und Grid Computing) kann eine Knappheit der zur Verfügung stehenden Ressourcen auftreten. Hier haben Marktmechanismen das Potenzial, Ressourcenbedarf und -angebot durch geeignete Anreizmechanismen zu koordinieren und somit die ökonomische...

Cost Estimating Certifications Offered by Professional Societies in the United States and Abroad
Remer, Donald S.; Ahle, Karen; Alley, Kevin; Silny, John; … - 2007
Many projects in industry and government go over budget and schedule. In most engineering economics courses, the emphasis is on how to compare alternatives and learn about time value of money and interest and inflation rates. The students are usually given the costs and asked to compare the...

A cell-based simultaneous route and departure time choice model with elastic demand
Szeto, WY; Lo, HK - 2004
This paper develops a cell-based formulation for the simultaneous route and departure time choice problem with elastic demands through a variational inequality problem (VIP). This formulation follows the ideal Dynamic User Optimal (DUO) route and departure time choice principle and encapsulates...
