Over the last few years, Grid technologies have progressed towards a service-oriented paradigm that enables a new way of service provisioning based on utility computing models. It provides services to users on the basis of pay-to-access as information technology utilities. The main challenge in utility Grid is to satisfy the user Quality of Service requirement, as well as minimizing the execution cost of workflow. The number of existing bi-criteria scheduling algorithms are usually dedicated for following utility Grid environment: fully connected network, and fixed data transfer time and cost (independent from selected services), utility Grid models. These scheduling algorithms are not suitable for arbitrary service networks (type of utility Grid environment), where services are distributed arbitrary.
