Reducing Downtime and Repair Times

Duration - 2 days


Poor maintainability starts at the design stage. Bad decisions made in this phase are with you for the life of the equipment unless you spend more money to put them right during the operation and maintenance phase.
Maintainability is the ease of repairing equipment and can be measured in terms of repair time, downtime, and man hours. There are a number of metrics such as MTTR, Mmax, Mean Downtime.
Improving maintainability results in improved availability and/or reduced unit costs of operation.
This very practical 2 day workshop covers a number of maintainability techniques to support improvements. The workshop includes a number of case studies and practical examples to aid understanding. Although the course concentrates on concepts we do use statistical analysis tools to illustrate obtaining solutions without the use of mathematics and reliability theory.
Reliability analysis is given high importance, however maintainability should also be given equal importance.

What you will learn

As a result of attending this workshop delegates will:

  • Have a better understanding of the factors affecting maintainability
  • Understand how to measure maintainability using steady state and time dependent measures
  • Have a greater awareness of techniques to improve maintainability
  • How to analyse the data held in the CMMS
  • Understand what needs to be done in the design phase to achieve good maintainability


Topic 1 Introduction to Maintainability

Topic 2 Measuring Maintainability
Steady state and time based measures, MTTR, MDT, Mmax

Topic 3 Overview of Maintainability Improvement Techniques
Model showing techniques for identifying issues and improvement opportunities

Topic 4 Maintainability in Design
Considering maintainability in the life cycle process, developing the specifications, human factors, mechanical handling philosophies
Conducting Maintainability Design Reviews

Topic 5 Maintainability FMEA
FMEA formats for tasks, spares and identifying high repair or downtimes or logistic times
