Design of Experiments (DOE)
Week 12 & 13 (Tutorial) For the tutorial sessions in week 12 and week 13, we were introduced to the concept of Design of Experiments (DOE). DOE is a statistics-based approach to designing experiments. It is a methodology to obtain knowledge of a complex, multi-variable process with as little trial runs as possible. It can be considered an optimisation of the experimental procedure itself. DOE is basically the backbone of any product design as well as any efforts to improve processes or products. Fundamentals of DOE Response Variable (Dependent Variable) Outcome that is measured for given experiment Factor (Independent Variable) A factor is a variable that is deliberately varied to see its effect on the response variable. Level A level of a factor is the specific condition of the factor for which we wish to measure Treatment A treatment is a specific combination of factor levels Case Studies For this
