  • Cornell’s famous fish patty experiment

    Cornell’s famous fish patty experiment refers to an experiment carried out by John A. Cornell, a leading figure in the development of mixture designs, a branch of Design of Experiments (DOE). The experiment has become well-known as an illustration of mixture designs in food product development. Background of the Experiment John A. Cornell used this fish patty experiment…


  • What is a Taguchi experiment?

    A Taguchi experiment is a method within the Design of Experiments (DOE) framework, developed by the Japanese engineer and statistician Genichi Taguchi. It is a structured, data-driven approach aimed at improving the quality of manufactured goods, optimising processes, and making products robust against variability. The Taguchi method is distinctive in its use of orthogonal arrays, its focus on…


  • Central Composite Design case study in chemical engineering

    Case Study: Synthesis of Pharmaceutical Compounds In the pharmaceutical industry, CCD has been used to optimise the synthesis of active pharmaceutical ingredients (APIs). For example, a study focused on optimising the yield and purity of a drug compound by varying factors such as temperature, reaction time, and reagent concentrations. Detailed Example: Pharmaceutical Compound Synthesis Let’s…
