ABSTRACT
Solving engineering problems requires that decisions be made
reliably and accurately towards the desired solution. Whether the
problem involves design and development, operation and
maintenance, or control and management, decisions must be based
on a solid model of the system that serves the purpose of the
solution. This systematic procedure leads to decisions that are
consistently reliable and reproducible. Furthermore, such a procedure
can be automated for efficient processing. On the other hand,
decisions made somewhat arbitrarily by engineers are open to
personal interpretation and inconsistencies.
