This paper presents a computer-simulation-oriented design procedure for a robust and feasible job shop manufacturing system based on the Taguchi approach and response surface methodology. The procedure includes optimal region investigation, optimal settings determination, and an adjustment procedure. The steepest descent technique finds the optimal region based on a weighted aggregated design measure. Then optimal settings are resolved and examined in an adjustment procedure to improve robustness. The proposed approach finally determines optimal settings so that the designed system is robust in production and economically feasible. A computer simulation example shows the applicability of the proposed approach.
