Design of Experiments (DOE) C1888


We need to “Improve the Way We Do Business” to survive in the modern global economy. DOE is a discovery tool to better comprehend the state of the business systems/processed at our organizations and optimize their performance in accordance to business goals. The DOE methodology addresses planning, execution, analysis and interpretation of a set of planned experiments designed to provide the road to improvement and ultimately optimization of the business system/process or product design under consideration. This methodology has been successfully applied countless times to solve quality problems and improve process improvement in basic sciences, economics, engineering and industrial sciences. Effective application of DOE has proven to: improve quality, reduce costs, reduce product/process development time, accelerate the pace of the learning process, reduce variation, and achieve consistent and on-target performance.

DOE allows the experimenters to realistically look at the impact of several factors and their interaction. This is far superior to the one factor at a time approach to experimentation. This leads to a quicker more efficient experimentation strategy. DOE strategies include statistical analysis (Analysis of Variance - ANOVA) to determine the significance of the results assuring that decisions made, based on the result of the experimentation, are sound. This course includes guidance on the application of ANOVA.

Genichi Taguchi made many contributions to Engineering and Quality, most notable were his techniques on applications of DOE. His techniques simplified the Experimental Designs. He introduced strategies such as: Robust Design, Parameter Design and the Signal to Noise Ratio which provide more information on the optimization of product and process designs. This course introduces the use of Taguchi concepts and techniques.

Learning Objectives
Upon completion of this course participants will be able to:
  • Define the DOE terminology and describe the methodology
  • Explain and employ the Taguchi methods for quality engineering
  • Evaluate quality losses due to variation (loss function)
  • Apply design of experiments to practical situations
  • Select the most economical and efficient test strategy during the planning phase
  • Carry out the selected test strategy and analyze and interpret the data generated
  • Conduct confirmation experiments to validate the conclusions drawn from the completed design of experiments
  • Describe and employ the parameter design methodology to make a product or process resistant to various environmental factors that change continuously with customer use
  • Describe and employ tolerance design concepts to achieve quality and cost requirements by strategically adjusting tolerances on appropriate specifications
  • Apply commercially available templates to DOE efforts

Who Should Attend
Product and Process Engineers involved in the optimization of specifications and related product or process performance. Quality professionals involved with problem solving relate to quality issue. Technical Managers who assist their staff in optimization and problem solving activities will be better prepared to support their teams.

Prerequisites
Previous participation or planning to participate on problem-solving and/or continual improvement cross-functional teams is useful in helping to efficiently employ DOE techniques.
