The aim of this study is to develop a program of simplex planning to solve various optimization problems. Program simplex planning software package written in Turbo Delphi. Simplex method of planning allows duplicate experiments at each subsequent step of the experiment, the largest number of experiments must be placed only at the beginning of the experiment. Then, in each optimization step is performed only one experiment
