Assigned Role Plan of Workflow Task Sequence Based on Back-Track Searching

With the increasing security requirements, authorization constraints must be fulfilled by the assigned roles of the workflow tasks. So the assigned role plan of workflow task sequence was proposed. First, the solution space of the assigned role plan was discussed. Then based on back-track searching, an assigned role plan algorithm was proposed aimed at that current assigned role plan algorithm had low efficiency. At last a simulated experiment was designed to compare the efficiencies of the two related algorithms.
