Performability
The analysis of a system from the pure performance viewpoint
tends to be optimistic since it ignores the failure/repair behavior in the
system. On the other hand, pure reliability analysis tends to be too
conservative since performance considerations are not taken into account.
Also, in a well-designed system, the failure of a component or subsystem will
cause partial outage of the system. Therefore, in real systems, reliability,
and performance are important indices which should be studied in a
composite manner. The combined evaluation of the indices described above
is useful when the system under study can operate in a gracefully degradable
manner in the presence of component failures. SHARPE and SPNP software packages
we have developed allows such combined performance/reliability analysis.
