Incorporating the potential for human error in maintenance models

Matthew Carr, AH Christer

Research output: Contribution to journalArticlepeer-review


The mathematics of delay-time modelling of inspection maintenance is extended to incorporate the existence of human error in the form of fault injection during the inspection process. After briefly discussing the basic delay-time model, modifications are introduced to model maintenance scenarios incorporating human error injected defects within the inspection maintenance process. The effects of human error are investigated with the emphasis on its representation and on the assessment of consequences, the objective being to provide a means of determining the cost of human error and to thereby aid corrective decision-making.
