The workflow actor interface toolkit: It includes Web-based workflow process definition tool, administration and monitor tool, and workflowapplication client-interface program. • Workflow process definition tool We provide two interfaces for process definition: one is script-based language (recall Activity Specification: An Example section), and the other is graphical interface that uses the graph-based concepts, such as nodes and edges between nodes (recall A Formal Model for Flow Procedure section).

TEAM LinG 40 Liu, Pu and Ruiz obtained by restructuring composite activities are the others (Figure 15 and 16). The analysis of the repercussions caused by a disturbance on the base and variant scenarios permit the evaluation of the possible benefits on restructuring the base workflow model. According to the simulation experiments, it is possible to state the restructuring of AllocateCircuit as being highly beneficial while the restructuring of AllocateLines is not.

In fact, the restructuring of AllocateLines would not result in effective elapsed time saving of activity instances. Consequently, the modeling of a business process by a hierarchy of activity patterns must present restructuring opportunities. Nevertheless, these restructuring opportunities must enable a considerable amount of saved elapsed time when activities are running on a disturbed environment. It is important that the restructuring process should take place only when the restructured workflow instance saves a considerable amount of time because such process restructuring takes time when performed.
