  • 1 Introduction to Reliability Engineering

  • 1.1 What is Reliability Engineering?

    This is a preview. There are 12 more flashcards available for chapter 1.1

  • How is customer acceptance that a product might fail regulated?

    - Warranty

    - Protection in law 

    Both come down to claim rectify for failures within given time
  • What is the downside of warranty etc for customers?

    It does not provide a measure of quality. Limitation of action when it fails multiple times or outside warranty period.
  • What are the consequences to the limitation of action when it comes to warranty?

    Manufacturer will suffer
    - loss of reputation, affecting future business.
  • Why do we use a time-based concept of quality when it comes to reliability engineering?

    Reliability is concerned with failures in the time domain. -> this is the distinguishing mark between reliable engineering and traditional quality control.
  • What aspect does reliability give us?

    Aspect of engineering uncertainty.
  • How can reliability be expressed?

    Number of failures over a period
  • What is Durability's connection to Reliability?

    Aspect of reliability related to ability of an item to withstand effects of time dependent mechanisms such as:
    - fatigue
    - wear
    - corrosion
    - electrical parameter charger
  • How can durability be expressed?

    Minimum time before the occurrence of wearout failures.
  • How is durability characterized in repairable systems?

    The ability of the product to function after repairs
  • What are the objectives of reliability engineering?

    In order of priority:
    1. Prevent or reduce likelihood or frequency of failures
      • by applying engineering knowledge and specialist techniques
    2. Identify and correct causes of failures that do occur
    3. Determine ways of coping with failures that do occur
    4. Analyzing reliability data
      • Apply methods for estimating the likely reliability of new designs
