WebThe simplex method is a set of mathematical steps for solving a linear programming problem carried out in a table called a simplex tableau. The initial simplex tableau for this model, with the various column and row headings, is shown in Table A-1. Table A-1. The Simplex Tableau. WebIn this tableau, the basic variables are x 3 and x 4, and the objective function is f. To find their values, divide the number in the last column by the number in the variable’s column. All non-basic variables have value 0. Here, x 1 = 0, x 2 = 0, x 3 = 480, x 4 = 1200, and f = 0. Since we are trying to maximize f, this is not a very good ...
