Abstract—A new condition-based maintenance model for a
system, subject to deterioration-failures and to Poisson-failures,
is presented. After an inspection, based on the degree of deterioration,
a minimal maintenance or a major maintenance
is performed, or no action is taken. Deterioration failures are
restored by major repair; Poisson failures are restored by minimal
repair. Major maintenance or major repair restores the system to
“good as new,” while minimal maintenance restores the system
one stage. Generalized stochastic Petri Nets are used to represent
and analyze the model, which represents a condition-based
maintenance strategy. Based on maximization of the system
throughput, an optimal inspection policy within this strategy
and optimal inter-inspection time are obtained. The effects of
inspection, maintenance, and repair parameters are investigated.
For a given inspection parameter, a 3-region diagram identifies
the effectiveness of an inspection policy based on minimal maintenance,
major maintenance, and major repair parameters.
