This thesis deals with the analysis of the Petri nets and the implementation of each application in different levels. The first chapter is an introduction, containing a literature review of the subject and an introduction to the theory of graphs, presenting concepts which will be used in other chapters. In the second chapter, Petri nets are analyzed, starting from their history and their definition and followed by their main components and properties and closing with modeling based on Petri nets. In the third chapter, the Petri net classes are introduced, followed by an extensive analysis of each one of them. In particular, the classes being analyzed are low-level Petri nets, high-level Petri nets, Petri nets with timed transitions, stochastic Petri nets and Petri nets with tails. In the fourth chapter, several applications of Petri net are described. This is being achieved by analyzing examples of low-level Petri network applications and high-level Petri network applications, Petri networks with timed transitions and a simple Petri model for weather forecast. In the fifth chapter, another two applications of a Petri net are being overviewed. In the first of these applications the Petri net is being used as a mathematical tool, whereas in the second it is used as a graphic tool. Finally, the sixth chapter states the conclusions that the present thesis has come to.
