Reliability Engineering Academy

Reliability Data Analysis

training number: Reliability_S02

Target group:

Engineers, technicians, specialists from the areas of development, testing, construction, research and quality assurance.

About the topic:

Life data from tests, field data from the warranty period and field data in general can exist in different forms and data quality. Numerous practical exercises are used in the seminar to show how Weibull analyses can be carried out and interpreted for different data structures independently and with the help of Minitab software. The analytical methods for the analysis of complete and censored datasets are covered. The focus of the seminar is the shape and quality of data-dependent, application-oriented selection of appropriate evaluation methods.

2-Day Training:

  • 1st day from 08:15 am to 05:15 pm
  • 2nd day from 08:15 am to 05:15 pm

Scope of services:

  • Training documents in paper form
  • Training documents as pdf document
  • Certificate of participation
  • Catering during the training

Training fee:

The training fee is 1,500.00 EUR excl. VAT.

Training content:

Day 1

Introduction
  • Introduction to reliability engineering
  • Reliability in the product development process
Mathematical Description of Reliability
  • Basic concepts of statistics and probability theory
  • Weibull distribution
  • Failure probability
  • Density function
  • Failure rate
  • Reliability
  • Confidence interval
  • Estimation of distribution parameters
  • Regression analysis
  • Maximum likelihood estimation

Day 2

Data Analysis I (Complete Data)
  • Median rank method
  • Weibull probability plot
  • Weibull analysis
  • Acceleration factor
Data Analysis II (Censored Data)
  • Type I and type II censoring
  • Multiple censoring
  • Weibull analysis based on censored data
  • Mixed Weibull
  • Batch problems
  • Competing failure modes
Various exercises

Various exercises provide an opportunity to apply and expand the knowledge learned practically. Several different applications are analyzed and the results interpreted together. Issues include:

  • When is a two-parameter or a three-parameter Weibull distribution suitable?
  • How big should the correlation coefficient be for a good fit?
  • What are the differences between the least squares method and maximum likelihood?
  • Is it a batch problem?
  • Are there competing failure mechanisms?
