Research on PPM of Software Project Schedule Controlling Based on OOPN

Object-Oriented Petri Nets (OOPN) combines Petri Net theory with object-oriented technology, which effectively solves the passible state explosion problem when modeling the complex systems with basic Petri Nets. The process performance model (PPM) is used to represent past and current software project schedule controllong performance. This article builds the PPM of software project schedule controlling with OOPN. Users can control and adjust the whole project schedule with PPM of software project schedule controlling. Building the software project schedule PPM with OOPN is more convenient and intuitionist than other modeling languages.
