Transcript

  • 1. FAILURE MODE EFFECTIVE ANALYSIS
  • 2.
    • Introduction
    • Failure Mode Effect Analysis is an analytical technique that goes in for combining Technology and Experience of people to identify foreseen failures in a product or process and planning to eliminate the Failure.
    • Definition
    • FMEA is a group of activities to understand and evaluate potential failure of product or process and its effects, and identify actions that eliminate or reduce the potential failures.
  • 3. Types of FMEA
    • Major Classification
    • Design FMEA
    • Process FMEA
    • Sub Classification
    • Equipment FMEA
    • Maintenance FMEA
    • Service FMEA
    • System FMEA
  • 4.
    • DESIGN FMEA
    • Design FMEA use in the design process by identifying known and foreseeable failures modes and ranking failures according to their impact on the product .
  • 5.
    • PROCESS FMEA
    • It is used to identify potential process failure modes by ranking failures and establishing priorities, and its impact on the Internal or external customers.
  • 6. RELIABILITY
    • Reliability is defined as the probability that the product will perform as per the expectation for a certain period of time, under the given operating conditions, and the given set of product performance characteristics.
    • The part, assembly, or process under consideration, the reliability of each sub system and factors that contribute to failure to be found.
  • 7. FAILURE RATE
    • Products follow a pattern of failure.
    • There is no information about the reliability (i.e. Failure) of the product.
    • Failure Rate is a constant is known period of failure can be found out using Exponential Distribution
    • R t = e – λ t R t = Reliability of survival
    • R t = e - t / θ t = Time for operation without failure
    • λ = Failure rate θ = Mean time to Failure
  • 8. PROBLEM
    • Failure Rate λ = .0002 per hour
    • What is the probability that it will survive or reliable during the first 200 hours of operations?
    • Solution
    Rt = e – λ t = e – (200) (0.0002) = 96.08 %
  • 9. END
