Temporal constraints model in the Management System of Experimental Consumables

The essential functions in the management system of experimental consumables for colleges are introduced. In the system three roles such as experimental college governor, experimental department manager and laboratory assistant are involved. After traditional workflow networks are recalled, Workflow network of temporal constraints oriented role is defined in order to build the interface among roles. It can effectively describe transitions according to different roles in complicated workflow processes constrained by time. Schedule properties based on the management system of experimental consumables are analyzed. Transition series both in a role and among roles are generated after a cooperative task is completed. Finally system implements are partly illustrated.
