RBAC role-permission assignment with conflicting constraints based on the E-CARGO model.

The multi-agent is now an established research topic of epistemology, in the view of ontology, multi-agent is usually related to role and agent is the executor of role, in this paper, we take research on multi-agent by solving the problem of RBAC role-permission assignment with conflicting constraints: the formalization, the description of conflict, and the algorithm are given based on the E-CARGO model, in the end, an simulation experiment is used to verify the correctness.
