Assignment 1: MRA Process and its design
This will allow you to determine how to approach a specific requirement for the review or development of a maintenance program.
What are the processes that can be employed in developing a logical approach to preventive maintenance program development for a particular situation?
What are the most effective ways to define system behavior so that the failure modes worth considering can be identified?
What logic should be applied to arrive at an effective and efficient preventive maintenance program?
Associated subject learning outcomes

As a team of 3, 2 or individually conduct the following tasks:
Smith in Chapter 5 of “RCM Methodology” (E-reading) outlines a seven step process to determine a baseline definition of the preferred PM tasks for asystem.
Provide a dot point summary describing the main features of Smith’s methodology for the first four of his process steps, i.e.:
System selection and information collection
System boundary definition
System description and functional block diagram
System functions and functional
These steps are described in Sections 5.2 to 5.5 inclusive. (Your answer should be 650 – 800 words long) (50 Marks)
Identify a critical asset or a set of assets/a system from an organization in any industry that you are working with or familiar If you do not have work experience, you can search for a critical asset and have enough industrial information, journal articles or reports on its asset management aspects to be familiar with.
Provide a description of the asset/system.
Establish a diagram illustrating where the asset fits into the overall hardware system and make simplified schematic diagram of the asset/system that defines the all its structure, subsystems/components and
Prepare a functional block diagram of the system in the format shown by Smith, 1993, “Reliability-Centered Maintenance,” Fig 5.8 (E-reading and also Slide 23 in Topic 2 Notes)
List the system functions and functional (15 Marks)
A key part of the RCM methodology has been the use of a decision diagram that guides the selection of a task to address a specific failure A number of these decision diagrams have been reproduced in the lecture notes for Topic 4.
What benefits do you see in using a decision diagram to aid in task selection? What would you include in such a diagram and why? (15 Marks)
