Maintainability

 

one of the chief characteristics of reliability; the suitability of equipment for the various procedures involved in technical servicing and repair. Maintainability is determined by the equipment’s operating and repair effectiveness. Operating effectiveness is the suitability of the equipment for procedures carried out during technical servicing and when the equipment is being prepared for operation, when the operation is in progress, and after the operation is completed. Repair effectiveness is the suitability of the equipment for rapid and convenient repair.

In the narrow sense of the word, maintainability is the suitability of equipment for rapid and convenient performance of specific production operations when the equipment is being serviced and repaired, when its technical condition is being monitored, and when its components are being dismantled, checked, replaced, and reassembled. When equipment is being designed and manufactured, maintainability is ensured by correctly selecting the design and performing all manufacturing operations exactly as specified. When equipment is being operated, maintainability is ensured by an efficient system of technical servicing and repair. Maintainability is characterized by the average time needed to return equipment to operating condition, the probability of returning equipment to working condition within a given period of time, operational readiness, utilization factor, interchangeability, and the degree of standardization.
