  • Snee & Marquardt (1976): Screening Designs for Mixture Experiments

    Snee & Marquardt (1976): Screening Designs for Mixture Experiments

    Snee and Marquardt’s 1976 experiment introduced an efficient screening design for mixture experiments, reducing complexity by identifying active components and simplifying optimisation.

  • Etch Rate Experiment (Myers & Montgomery, 2002)

    Etch Rate Experiment (Myers & Montgomery, 2002)

    This case study explores the Myers and Montgomery (2002) etch rate experiment using response surface methodology (RSM) to optimise plasma etching in semiconductor manufacturing. A central composite design is used to model the effect of RF power and chamber pressure on etch rate.

  • Using Mixture–Process Variable Experiments: A Rocket Propellant Case Study

    Using Mixture–Process Variable Experiments: A Rocket Propellant Case Study

    Learn how mixture–process variable experiments can optimise formulations and processing conditions in real-world engineering. This case study on rocket propellants shows how combining mixture design with process variables improves product performance and scale-up reliability.
