Using Trust and Self-Confidence for Coalition Formation in Migrating Workflow

An experience based trust model in migrating workflow is proposed. In the trust model, security and capability are considered in a cooperation evaluation, a cooperation evaluation sequence is updated according to update strategies and the trust degree is acquired using the trust degree formula. Self-confidence of the workplace is defined based on our former research in agent ability self-confidence. After that, a coalition formation mechanism based on trust and self-confidence in migrating workflow is presented. Compared with related works, our trust and self-confidence based coalition formation mechanism can not only ensure former agents with high trust degree to remain their membership, but also allow fresh efficient agents to join in the coalition. Therefore, the security and efficiency of business process execution is well guaranteed.
