WEIGHTED MULTI-CRITERIA WORKFLOW TASK ASSIGNMENT

摘要

Authorization constraints are usually used as a necessary component to meet complicated security requirements such as task assignment in workflow systems. But such authorization constraints will result in high exception probability if they are strictly fulfilled. To reduce the exception probability, the security risk coefficient was introduced and a weighed multi-criteria workflow task assignment model was proposed. By analyzing the reasonability of the task assignment of the given instances, it was validated that the model was usable.
