Distributed environments with the decoupling of users from resource providers are generally termed as utility Grids. The paper focuses on the problems of efficient job flow distribution and scheduling in virtual organizations (VOs) of utility Grids while ensuring the VO stakeholders preferences and providing dependable strategies for resources utilization. An approach based on the combination of the cyclic scheduling scheme, backfilling and several heuristic procedures is proposed and studied. Comparative simulation results are introduced for different algorithms and heuristics depending on the resource domain composition and heterogeneity. Considered scheduling approaches provide different benefits depending on the VO scheduling objectives. The results justify the use of the proposed approaches in a broad range of the considered resource environment parameters.
