一种新改进单纯形优化方法

A New Modified Simplex Optimization Method

本文采用模糊数学方法计算了多指标综合评价值,并以它作为单纯形优化的目标函数,建立了一种新改进单纯形优化方法,改进了反射基点、形心点和反射系数的计算方法。

A new 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 bL participate in the calculation for basical point of reflection. A fuzzy 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.
