A workflow optimization by handling subjective attributes with meta-heuristic approach

Decision making of worker for appropriate task selection based on workflow is often changed by occurring interruption. Concerned workers of interrupted workflow must optimize workflow to improve consumed time of current tasks by changing engagement of assigned tasks. Although work efficiency is improved by supporting experienced worker for inexperienced worker, time for nurture of inexperienced worker is decreased. In order to minimize the payoff of expected profit for forthcoming work, appropriate task selection of the worker in interruption must approximate to weight of common criteria by pre-task assignment as an ideal task selection through the superior decision maker. Proposed approach in this paper improves the achievement changed of tasks in certain interruption by applying meta-heuristic approach according to subjective attributes of worker.
