Service-oriented environments have distinctive characteristics, such as being dynamic, open and distributed. The evaluation of trust and reputation is very important in establishing secure interactions between web services in such environments. Many trust models have been developed based on feedback mechanisms. However, not all of them are able to detect false reputation outcome as a result of misleading data provided by raters. A key challenge to employ these models is to prevent user’s misbehavior in unfair feedbacks and ratings. In this paper, a new trust model based on ELECTRE TRI method is proposed to overcome such a challenge. To evaluate the effectiveness of the model, the results are compared with the well known RATEWeb model. Numerical results and performance evaluation of our model proves its ability in trust management as well as quick adaption of behavioral changes of service providers.
