Expected Results

[ ToC ][ Top ]

The main practical goal is to provide an environment for modelling and simulation of discrete event systems allowing a user to easily describe a model (using model bases, hierarchical descriptions and modular models), and to simulate it. In this project we will face the application of this environment in the modelling and simulation of complex urban traffic models. The goal is to execute microsimulations to solve congestion problems, traffic light synchronization, improvement of traffic flow using new traffic rules, etc.

From the theoretical point of view, the formal definitions presented in the Introduction are being finished. At present new algorithms for syncrhonization in parallel/distributed environments are being introduced. Experimental evaluation of the new proposals will be faced, in such a way to obtain a parallel simulation environment that can be used as a basis for different distributed applications. The main emphasis will be put in Cell-DEVS models.

The tools can be applied in different problems:

• Industrial application: circuit design, material traffic flow in industrial environments, robot trajectories, virtual reality, microbiology models, etc.
• Educational application: the environment can be used to include a wide variety of models that can be applied in different fields: physics, chemistry, biology, computer science, etc.
• Parallel simulators: the results obtained in parallel simulation can be applied in a wide variety of real system application. The performance of the simulations can be improved by achieving speedups in the results collection.
