Availability, Reliability & Maintainability (AR&M)
This is an in-depth course using a hands-on approach. This course presents a practical review of AR&M by presenting an overview of acquisition phase objectives and their application in the design and development of equipment and systems. Topics covered include: Principles and Objectives; Consideration of underlying failure mechanisms; Engineering Techniques; Allocations and Predictions; System level modelling; Data Collection & Analysis; Verification Testing in a Life Cycle Context. The course closes with a general discussion and the opportunity for delegates to further address any particular issues which may be of interest to them.
The format of this course allows for maximum information to be presented while allowing for questions, discussions, and in-class examples and exercises to maximize the students overall learning experience.

Is this course for me?
AR&M Engineers and Managers, ILS and Supportability Engineers and Design Engineers wishing to expand their understanding of these principles.
This course is endorsed by the Chartered Institute of Logistics and Transport (CILT) and contributes to Continuing Professional Development (CPD) hours.
This course does not just show delegates the simplistic solutions which are used every day to calculate and treat AR&M; it also addresses the foundations on which AR&M theory is based and the engineering mechanisms and processes which underlie the achievement of Reliable, Maintainable systems. The role of Reliability Quantification within Systems and Reliability Engineering is discussed and delegates are exposed to the methodologies which can be applied to complex systems in order to maximise their beneficial effect. The importance of reliability to system design is a significant element of the course.
AR&M management processes and AR&M engineering activities are discussed to provide detailed knowledge to the delegates. Finally, the issues of contracting successfully for AR&M are discussed from both the Supplier and Purchaser stand points. Major AR&M issues are supported with practical examples and exercises which ensure that the delegate acquires both a robust understanding of AR&M theory and real practice of producing solutions.
Pre Course Preparation
A maths refresher sheet showing some of the notation that will be used for parts of the course will be sent to all delegates prior to the start of the course. A lap-top computer with MS Excel would assist delegates with some course discussions and exercises.
There is an optional, evening tutorial on Day 2 to allow students the opportunity to practise the maths that they will be applying later in the week.
Module 1: Maths and Stats Applications in ARM
This is short overview of the main statistical concepts applicable to Reliability & Maintainability mathematics. It is provided as an additional session of approximately 1.5 hours during the first 2 days of the course. This is supplemented by a short refresher which is also provided as prior reading to remind delegates of mathematical notations, data series and the principles of Calculus (Note that very little calculus is used during the course, however, the principles of differentiation and integration are used to illustrate discussions on AR&M). AR&M mathematical theory also utilises the concept of probability; and the basic Probability Laws are summarised to enable AR&M to be more fully understood.
Module 2: System Measures & Metrics
This lesson introduces the delegate to the definitions and significance of AR&M as the primary driver of Through Life Costs. It considers the characteristics and relationships that contribute to the Availability of a System and addresses the major terms and parameters used when addressing Reliability, Maintainability and Testability.
Module 3: ARM & Systems Engineering
This session examines ARM within the context of a Systems Engineering process and discusses the significant standards which are relevant to an effective R&M programme.
The application of ARM during the Acquisition Cycle is also discussed and the differing focus and objectives during a Product Realisation Process considered.
Module 4: Causes of Failure
This session addresses the question ‘why do things fail?’ and examines and discusses the underlying causes of failure and contributory factors for Electrical/Electronic, Mechanical and Software elements of a system.
It also considers the underlying causes and effects for Human related errors and the contributions to System un-reliability.
Module 5: ARM Management & Engineering in the Lifecycle
The Management of an R&M programme throughout the lifecycle and the major objectives and activities are identified and discussed in this session.
The principle of progressive assurance and the R&M Case is presented with emphasis on “growing” a body of evidence.
Module 6: R&M in Design
This session considers the R&M Products & deliverables addressed from both a Customer’s and Supplier’s perspective. The Contracting and ARM Management considerations include Purchaser requirements and contractor implementation together with ARM Specifications & ARM documents encompassing Planning, Technical reports and the R&M Case.
Module 7: R&M Engineering Techniques
The “engineering design” phase is addressed in this session. Many of the tasks conducted in this phase are procedural in nature and the principles and application are discussed to a suitable depth with appropriate examples. The significance of techniques such as FMEA (Failure Mode Effects Analysis) and FTA (Fault Tree Analysis), RCM (Reliability Centred Maintenance) and other methods are emphasised within the context of achieving a reliable system design. Practical FMEA, FTA discussions and exercises are performed by delegates and the concepts and issues discussed.
Module 8: Reliability and Maintainability Allocation Modelling and Prediction
This is an extensive session with many practical examples and exercises that presents and discusses techniques which can be used in the ‘specification and technical planning and the ‘engineering design’ phases of a reliability programme. The session commences with the apportionment/allocation tasks and their objectives, benefits and shortcomings. Reliability predictions are then discussed together with the differing techniques which can be utilised for different technologies (e.g. Electrical/electronic, Mechanical & Software).
Finally, reliability modelling is discussed in depth addressing: block diagrams, different configurations, various redundancy techniques and various modelling methods including RBDs, Scenario modelling and Markov Analysis.
Module 9: Reliability Growth, Data Collection and Analysis
This session includes not only a discussion of DRACAS/FRB activity, but also addresses Reliability Growth/HALT trials and Accelerated Life Testing. The topic of data analysis, includes consideration of the major statistical distributions (Normal and Weibull in particular) and other concepts such as Bayesian Analysis. Understanding reliability testing and data analysis with the underpinning principles enable delegates to quickly evaluate and soundly articulate the commercial risks involved for both the purchaser and the supplier. Delegates are involved in analysis of data using both Normal and Weibull distributions and the interpretation and discussion of results.
Topics addressed include;
- DRACAS and Failure Review Boards
- Reliability Data Analysis
- Reliability Growth
- Accelerated Testing
- Bayesian Analysis
- The practical manifestation of Warranties and Guarantees
Module 10: Statistical Demonstration
This session examines and discusses the principles and concepts underlying statistical R&M demonstrations and their potential role within both formal acceptance and verification and Progressive Assurance approaches.
