ABSTRACT Petri nets play an important role on modeling biological as well as technical systems. They are useful in modeling and simulation of technical as well as biological models.Therefore, adopting an interactive technique like computational steering which allows users to change key parameters and variables during the simulation execution rather than waiting for the end of the simulation. However, the execution of Petri net models is usually carried out in a non-interactive way. Computational steering provides more powers to the simulation of Petri nets. However, currently available tools to implement the steering of Petri nets models are not flexible to run differentplatforms and devices. Furthermore, the currently available simulators of Petri net models take a long time and the users are not able to change key parameters during the execution of the simulation.Petri nets and computational steering provide a powerful tool both on the representation and simulation level. Moreover, web applications facilitate the easy experiments with new models and technologies with minimal technical support. In this paper we introduce a framework to steer Petri net models via the web. This framework will present morefacilitiesto the usersin order to steer and simulate Petri net models without having to install anything locally on their computers. Additionally, this study proposes a flexible and versatile framework that supports the steering of Petri nets models on the web. The framework is based on Snoopy steering server and can run on a highly distributed manner.Moreover, it permits users to see the results of the model’s simulation immediately.
