Guidance on in-Service Reliability and Maintainability (R&M)
Definitive Guidance for the Acquisition Management System
1. Introduction
1.1 This document aims to illustrate the importance of in service R&M, to discuss reasons why in service R&M data may be collected and to provide guidance on how this may be achieved.
2. Definitions
2.1 Reliability can be defined qualitatively :
“The ability of an item to perform a required function under stated conditions for a specified period of time”, (Allied Reliability and Maintainability Publication – 7 (ARMP-7))
Or quantitatively:
For example Mission Reliability is defined as “The probability that an item will perform its required functions for the duration of a specified mission profile”, (ARMP-7).
Note: There is a very wide range of potential quantitative reliability metrics and care must be taken to select only those which are relevant to a particular equipment and its operating profile.
2.2 Maintainability is the probability that a given maintenance action, for an item under given conditions of use, can be carried out within a stated time interval, when the maintenance is performed under stated conditions and using stated procedures and resources, (ARMP-7).
2.3 Availability is the probability that the system or equipment used under stated conditions will be in an operable and committable state at any given time, (ARMP-7).
Note: There are a variety of sub-definitions of availability that are meaningful in different operational and management situations. Further details can be found in Def Stan 00-49/Issue 1 and ARMP-7.
3. The Impact of In Service R&M
3.1 The intrinsic R&M of any equipment is entirely defined by the design and the assumptions that this makes about the operating environment. Poor production...
