This thesis deals with the reliability and maintenance of structures that are damaged by shocks arriving randomly in time. The degradation is modeled as a cumulative stochastic point process. Previous studies mostly adopted expected cost rate criterion
for optimizing the maintenance policies, which ignores practical implications of
discounting of maintenance cost over the life cycle of the system.Therefore, detailed analysis of expected discounted cost criterion has been done, which provides a
more realistic basis for optimizing the maintenance. Examples of maintenance policies
combining preventive maintenance with age- based replacement are analyzed. Derivation
for general cases involving preventive maintenance damage level have been discussed.
Special cases are also considered.
