Aims

To demonstrate expertise in Availability, Reliability and Maintainability (ARM) assessment methods and how to apply them to improve maintenance management, maintainability and reliability.

Learning Outcomes

1.
Identify and apply the analysis methodologies to systems and sub-systems, including both design and operation restrictions, to determine the Availability, Reliability and Maintainability of these Systems.
2.
Critically review and balance the requirements of the design for ARM and safety.
3.
Logically deduce how ARM results for a system may be improved.

Module Content

Outline Syllabus:Introduction to Availability, Reliability and Maintainability (ARM): -Definition of Terms -Importance of ARM -Defining the Mission -ARM Targets and Target Apportionment Availability and Safety – Potential Conflicts -Differences Between Safety and ARM -Claims on Repair ARM Planning and Choice of Methodology -ARM Planning -Interpreting ARM Targets -Incorporating ARM Into the Design -Choice of Methodology -Dealing with ARM Shortfalls ARM Assessment Methods – Deterministic -Failure Modes, Effects and Criticality Analysis (FMECAs) -Categorising Component Failures -Limitations of FMECA -Functional Block Diagrams Numerical ARM Assessment Techniques -Parts Counts -Fault Tree Analysis -Reliability Block Diagrams Critical and Life Limited Items -Critical Items – Novel, Expensive, Difficult to Repair -Limited Life Items Maintainability and Maintainability Demonstrations -Incorporation of Maintenance into Design Reliability Centred Maintenance (RCM) -Definitions of RCM -Processes, Requirements and Limitations Methods of Improving Reliability
Additional Information:The module aims to enable students to apply correctly the appropriate ARM methodologies to a project to ensure that ARM is included within the design and that the ARM targets are met. The module also illustrates how ARM activities should be planned, and targets set. It also discusses the concept of critical and life limited items and the use of reliability centred maintenance strategies to reduce maintenance costs. Finally the module considers the trade-offs between ARM and safety requirements, as well as discussing how ARM shortfalls may be addressed. Assessment is in the form of an essay combined with activities (e.g. exercises, discussions, etc.). The module is delivered via distance learning, described as follows: Lecture (using slides and slide notes): Online self-study Tutorial/Activities (Exercises and reviews): Online activities with teacher feedback, and virtual classrooms Tutor-supported Online: Tutor feedback for activities, virtual classrooms and email support
