This paper concentrates on the application of schedule-based methods which allow both efficient handling of QoS requirements as well as traditional machine usage objective. An incremental application of our methods reacting on dynamic character of the problem allows to achieve reasonable runtime. Even more, we show that the schedule-based methods significantly outperform queue-based approaches by means of the weighted machine usage reflecting heterogeneity of the resources common for the Grid environments. A new formalized description of two schedule-based methods is introduced to schedule dynamically arriving jobs onto the machines of the computational Grid. Proposed methods are compared with some of the most common queue-based scheduling algorithms. ER -
