A Grid Reputation Model Based on Service Quality

At present most of the reputation models haven´t consider enough about the context of the entities ´s conduct, no define and no evaluate about the multi-act properties. In responding these issues, referencing on the trust relationship of society and introducing the multi-service properties, we propose a grid reputation model based on service quality. According to its own characteristics, the service is divided into multi-service properties. The service requesters evaluate multi-service properties comprehensively of the service providers which according to their own preferences, and combine with the credible value, then decide whether to perform the transaction. After the transaction, the service requesters calculate the different degree based on the actual service quality and the service quality that the providers´ claimed. Then they decide whether the providers credible and carry out the amount of credibility. Simulation results show that this model has a better evaluate results.
