Project management processes modelling using Petri nets

In the paper, a new approach of Petri Nets using to processes modelling of project management and Subsequently to generalization of modelling abilities of Petri nets is presented. It describes how a technique of Petri Nets can be used to model and subsequent monitoring of software projects realization behaviour. The main Purpose of this article is to simplify the process of project realization through creation and subsequent optimization of variant softwarc project plans (especially for application in different domains of software engineering). These plans are created as Petri nets which allows LIS to optimize them by Petri Nets techniques and tools application. The possibility of project control processes verification especially with the knowledge of quality management field will contribute to the development of sophisticated Information Security Management System.
