QoS Driven Dynamic Task Assignment for BPM Systems Using Fuzzy Logic
Abstract
Adoption of standards-based business process management systems is picking up. With this trend the need for novel techniques for process optimization is growing. One such technique is managing task assignment to resources at runtime. In this paper, a state-of-the-art task assignment algorithm that considers worker skills, task relationships, worker relationships and worker workload has been extended in two different manners: First, the historical evaluation of the workload of each worker has been added; and second, the quality of service (QoS) criteria has been introduced to be evaluated as the worker skills and workload are done. In addition, the task assignment solution has been designed and implemented on a business process management system.
