SDL

The paper introduces a novel method to represent slab avalanche phenomena.
The model is based on a cellular automaton generalization named m:n-CAk. This generalization allows the use of
different layers in a single cellular automaton. Each one of these layers represents the GIS data needed to perform the calculations. The model is represented using Specification and Description Language, and is implemented in

Abstract: In this poster we show how to use Specification and Description Language (SDL) to represent cellular automata models. To achieve that we use a generalization of the common cellular automata, named m:n-CA^k. Also we add some extension to SDL language to simplify the representation of these automata. Thanks to SDL and m:n-CA^k the behavior of the cellular automata model can be defined in a graphical way allowing the complete and unambiguous description of the simulation model that uses it.

Formal languages become important tools since allows the complete understanding of the model and helps in its implementation. However only few simulation tools allow an automatic execution of a simulation model based in a formalization of the system. Specification and Description Language is a modern object oriented

SDL is a graphical language, standardized under the Z.100 recommendation, widely used to represent telecommunication systems, process control and real-time applications in general. In this paper we have three objectives, first present an algorithm that allows the transformation of a DEVS specification to an SDL specification. Second we present a XML representation for the SDL language; this XML representation can help in an automatic transformation of the SDL model representation to a DEVS model representation.
