Object oriented performance models with knowledge-based diagnostics
Mohsen Pazirandeh, Jeffrey M. Becker · 1987
The performance modeling of computer systems plays an important role in the system engineering life cycle. Historically, however, this important role has not been recognized, and often it has been treated as an obligation. The reason for this diminished stature has many causes, but foremost is that performance modeling has failed to position itself as an indispensible tool to system designers. This single cause itself has many contributors, two of which are the most visible. First, modeling has come to be viewed as an esoteric exercise because of its inability to reflect the system architecture and other system characteristics with ease. Second, the output of most models is a set of statistical data, hardly pointing to a specific design deficiency or operational failure.
