Maintainability and its Influence on System Safety

  • Cris Whetton


Maintenance is the totality of technical and administrative actions taken to retain an item in or restore it to its designed operating condition. Maintainability is the systematic assessment of the effectiveness of maintenance strategies and can have considerable influence on system safety; as such, it is more concerned with the design of the system than with the procedural or management aspects of maintenance. This paper introduces the concepts of maintainability as they relate to safety, concentrating on corrective maintenance and suggesting some of the ways in which these concepts can be applied. (In order to do justice to the subject, preventive maintainability is not covered.)
