6 CONCLUSIONS
In this paper, we propose an approach for optimizing
PSMs using model-driven transformations. Since this
approach selects from several generated PSMs (ac-
cording to given optimization objectives), it requires
an engine supporting that more than one transforma-
tion rule can fire on the same source pattern. Of
course, it also requires that at least some rules exist
where this actually happens.
In a case study in the context of model-driven gen-
eration of graphical user interfaces, we studied rule
design for such an approach. Such a rule design has
its own intricacies, but we even found possibilities
for reuse of rules for generating several PSMs (for
GUIs on several devices). On an existing platform
that supports this approach, optimization for several
such GUIs was actually possible with the rule set de-
signed.
