5 CONCLUSIONS AND FUTURE
WORK
This paper shows how we can model environmental
systems using Specification and Description
Language. To do this the main concern is how
model the behavior of cellular automata graphically
using SDL, and how to manage time.
Two examples are quoted, a representation of a
Fibonacci function over a cellular automaton, and
the fire spread following the Behave model.
Two proposed extensions to SDL are shown, one to
manage time on the SDL signals and other to
simplify the representation of the cellular automaton
structures.
The future work is focused in the verification of the
implemented structures on SDLPS and the use of
this system on some ongoing real projects involving
industrial models or environmental models.
