Abstract
Hybrid systems are defined as systems that exhibit mixed properties of
continuous-time systems, discrete-time systems, and discrete-event systems.
The paper analyzes various aspects that need to be taken into consideration
when modeling such systems for the purpose of a numerical simulation. It
addresses issues related to the convenience of the modeler when dealing with
such systems, as well as issues related to the numerical properties of the
generated simulation code. It shows that the difficulties encountered in
modeling such systems are quite different in nature from those encountered in
simulating them. When addressed in their proper contexts, these two types of
problems can almost totally be decoupled from each other. A set of guidelines
for the design of hybrid modeling and simulation software is derived that may
support future software designers in their attempt at developing products that
are both more user-friendly in terms of their modeling capabilities and more
robust in terms of their simulation capabilities.
