Abstract:An improved IDEF3 method was presented to describe a great lot sequence, paralleling, synchronization, conflict and consequence relation during discrete event simulation using WITNESS software. Integrated principles of semantic methods and simulation rules of junction along with integrated methods of information data and units of behavior were put forward for the reconfiguration and reuse of simulation units. New behavior units were also advanced to simplify the modeling process. At last, a framework of simulation and dispatching rules were given based on the improved IDEF3 method. The detailed modeling process was demonstrated through WITNESS simulation software. The methods could improve greatly the speed of simulation modeling and decrease the difficulty of modeling.
Keywords:improved IDEF3 method  discrete event  simulation modeling
