Design of Experiments (DoE)

Design of Experiments is a vital business improvement technique. It allows organisations to improve quality, reduce operational costs and reduce waste and rework in a minimum time and at minimum cost. Experiments can be devised to improve existing processes, develop new products or develop new processes. Typical DoE projects:

  • In the food industry, the effect on yield of process factors such as temperature, pasteurisation of raw milk and casein was investigated
  • In the plastics industry, the effect on hardness of process factors such as resin temperature, gravity of resin and oven temperature was investigated
  • In marketing, the effect on product rating of the type of consumer and method of advertising was investigated

DoE can be used to answer questions such as:

  • What are the key factors or factor interactions influencing a process, or contributing to a problem?
  • Which combination of factor ‘settings’ minimises variation in the process output?
  • Which combination of factor ‘settings’ optimises the process output?
  • The course content includes problem definition, selecting responses & factors, scoping studies, layouts, screening designs, Taguchi methods, fractional & full factorial designs and response surface methodology (RSM).

Both our standard and bespoke courses are suitable for those with no prior knowledge of DoE or for those who require a refresher programme. For further details contact ISRU.
