Failure frequency
Frequency of inspections
Inspection costsInspection costs at various cycles can be determined but these should also allow for disruption to the operation of the building.
Failure costsThe failure frequency at each inspection cycle can be determined from the graph.
Failure costs, including disruption, can then be identified over the range of replacement cycles.
An optimization can then be carried out either by graphical means of by mathematical methods to determine the most effective inspection cycle.
Replacement costsReplacement costs at various cycles can be determined but these shouild also allow for disruption to the operation of the building
Failure costsThe probability of failure can be determined from the frequency distribution.The probable cost of failure, including disruption, can be found for the range of replacement cycles.
An exercise can then be carried out either by graphical means as suggested below or by mathematical methods to determine the optimum replacement cycle.
