CONTROLLING TASK EXECUTION

摘要

A specification of a graphical representation of task dependency has a plurality of task elements each associated with a different task, a resource element having a plurality of attachment locations, and linking elements coupling the task elements to the resource element at the plurality of associated attachment locations. Associations of task elements to attachment locations on the resource element specify an ordering constraint on the tasks associated with the task elements. The tasks are executed according to the graphical representation of task dependency.
