Abstract: Anew modified simplex method of optimization was developed, in which the calculating methods for basical point of reflection, centroid and reflection coefficient were improved. All the points whose comprehensive evaluation values are bigger than the evaluation limit value, namely bL, participate in the calculation of centroid, Pc, whereas those points whose values are smaller than bLparticipate in the calculation for basical point of reflection. Afuzzy comprehensive evaluation function, which contains several parameters, such as chromatographic peak height and area, resolution, noise and analysis time is used as a goal one for evaluating result of simplex optimization in the transference of simplex.

Key words: Fuzzy comprehensive evaluation, Optimization, Simplex
