Abstract

The integration of Planning and Scheduling (P&S) and Workflow is a significant challenge for knowledge acquisition in planning and scheduling. There has been some work on the definition of workflow that allowed non-experts entering knowledge on the organization process to be used in planning and scheduling. To date, however, temporal constraints handled in the workflow model for planning and scheduling has been little explored. This paper describes a means to exploit workflow patterns in modeling of planning and scheduling. And temporal constraints are presented and propagated on an associated Simple Temporal Network in order to check temporal consistency in the modeling phase. We also propose a graphic modeling tool. It helps users to modeling and acquiring knowledge conveniently.
