Abstract—In general, software development process is modeled by discrete models or continuous models, but they are not
enough to completely describe the behaviors of software
process. According to the characteristic of software
development process, it is a typical hybrid system which
includes continuous factors and discrete factors. This paper
introduces hybrid Petri nets into modeling for software
development process. The main emphasis is on the
construction of an adequate model for software development
process in order to bring convenience to software project
management. The example model reveals that the hybrid Petri
nets model is promising for exactly describing the software
development process.
