A DoE approach in which designs are generated based on an optimality criterion. A sparse method often used when there are resource limitations.

In D-Optimal, the determinant of the matrix of parameters is maximised.

Advantages

  • Useful when there are resource limitations
  • Can be tailored to optimise the parameters of interest

Disadvantages

  • Will not represent the design space as thoroughly as other approaches, such as Central Composite
  • Not very structured, can vary depending on the optimisation method
