Abstract
BPMS (Business Process Management Systems) is a revolutionary information system that supports
designing, administrating, and improving the business processes systematically. BPMS enables the execution
of business processes by assigning tasks to human or computer agents according to the predefined definitions
of the processes. In this paper, we devise process execution rules using individual worklists and
propose task assignment algorithms to maximize the overall process efficiency under the limitation of
the agent s capacity. We first transform the business processes into queueing network models, in which
the agents are considered as servers. With this step complete, workloads of agents are calculated from server
utilization and the task assignment policy can be determined by balancing the workloads. This will serve
to minimize the workloads of all agents, thus achieving overall process efficiency. Another application of
these results can be capacity planning of agents in advance and business process optimization in the reengineering
context. The simulation results and comparisons with other
