Workflow management system (WFMS) has been used in various business processes fo r the recent time. In business processes, buyers and suppliers define an agreeme nt or contract between the two parties, specifying quality of service (QOS) item s such as products or services to be delivered, deadlines of delivery, quality o f products, and service charge. Organizations operating in modern markets requir e an excellent service management. When services or products are created or mana ged using workflow processes, the underlying WFMS must predict, monitor, and con trol the QOS rendered to customers according to specifications of the agreement . To achieve these objectives, the first step is to develop an appropriate QOS m odel for workflow processes and develop methods to compute QOS.
