Optimization-assisted Taguchi method

The optimization-assisted Taguchi method extends Taguchi's robust design framework by coupling its orthogonal-array experiments with a secondary optimization algorithm — such as grey relational analysis, genetic algorithms, or particle swarm optimization — to simultaneously handle multiple response variables or to navigate a larger design space than pure Taguchi arrays can efficiently explore. The result is a structured, data-efficient experimental strategy that yields both robust parameter settings and globally near-optimal solutions.
