A workflow optimization by handling interruption with meta-heuristic approach

Decision making of worker for appropriate task selection based on workflow is often changed by occurring interruption. Pre-assignment by superior decision maker is one of criteria for the task selection. Expected task achievement by pre-assignment is changed by occurring interruption due to inserting external activity to the worker. Interruption consumes usable time for the current workflow by operating generated new task. The concerned workers of interrupted workflow must optimize workflow to improve consumed time of current tasks by changing engagement of assigned tasks. Proposed approach in this paper improves the changed achievement of tasks in certain interruption by applying meta-heuristic approach.
