Enterprise modeling is a new area of considerable current interest to
chemical processing industries. Similar to the approach of the Process
Systems Engineering community, the Enterprise Modeling community atte
mpts to construct models of total systems rather than individual piece
s. This paper will examine WHY Enterprise Modeling has caught industry
's attention, continue with an example of how Enterprise Modeling has
been applied in a restructuring project at a gas processing plant in N
orway, WHAT Enterprise Modeling is, what kind of problems it may be us
ed to address, and finally HOW Enterprise Modeling fits in with our Pr
ocess Systems Engineering tradition.
