Workflow management systems provide a cooperative-work environment for the modern enterprises
which can availably manage enterprise business process and enhance its business competence.In order to efficiently manage the schedule of business processes
it is necessary to provide a schedule estimating method for workflow process model.The process modeled by workflow net based on Petri nets is difficult to be estimated for its schedule and total time directly.While in traditional schedule planning
the PERT diagram is an available technology.This paper introduces time concept into the workflow net and presents a transformation algorithm from LMST-invariant’s subnet to PERT diagram based on LMST-invariant decomposition.According to the resulting PERT diagram
the schedule and total time of workflow process model can estimated.
