).
?– It has many implementations. International standards simply aren ??™ t worth the
paper they are printed on (or the hard disk space they occupy) if they are
not implemented. Even before the SysML fi nal specifi cation became available
in early 2006, several companies announced implementation of the standard.
It is important to understand that SysML is not just another software development
modeling language. While software is an important component of nearly all
complex systems today, it is almost never the only component??”planes, trains, and
automobiles all have software, and so do building controllers and chemical plants,
but they also have plumbing, hydraulics, electrical, and other systems that must be
harmonized and co-designed. Likewise the human and automated processes to use
complex systems need to be mapped out as well in order to get good use from
them (as well as maintain and integrate those systems for future requirements and
into future systems). And all of these co-design issues need to take into account
the fact that all complex systems are available in multiple configurations, based on
facilities requirements, personnel hiring issues, and myriad other variables.
