Bilateral Bargaining Game and Fuzzy Logic in the System Handling SLA-Based Workflow

In the business Grid, the owner of a workflow is assumed to ask an SLA Workflow broker to execute the workflow for him. The price for executing a workflow on the Grid is negotiated between the user and the broker. Determining a price that satisfies both, the user and the SLA workflow broker, is a difficult task. This paper proposes a method using bilateral bargaining game model based on fuzzy logic to determine the price that the user and the broker could accept after the first negotiation round. We also analyze many parameters affecting the price determination process. The validation results show that the approach is suitable with business rules.
