Simplex Optimisation Technique for Development of Rubber Formulations

摘要

A Simplex technique for optimization in the presence of error is presented and the use of the technique to develop a rubber formulation for an acoustic application is described. The technique is very useful in the early stages of optimization, permitting a rapid approach to the optimum with minimum experimentation. However, in the later stages, as the optimum is approached, it is doubtful if the Simplex technique offers any advantage over simple extrapolation and one variable optimization. A combination of both techniques seems to be appropriate in most cases with the end of the first, Simplex, phase being reached when oscillation or spiralling of the Simplex plot prevents new combinations from being generated.
