The Simplex algorithm is a popular method for numerical solution of the linear programming problem. The algorithm solves a problem accurately within finitely many steps, ascertains its insolubility or a lack of bounds. It was created by the American mathematician George Dantzig in 1947.

Write the resulting LP and the corresponding initial Phase I simplex tableau. What is the basic feasible solution in this tableau? Solution. Unit 1 Lesson 6: Simplex Method • Set up and solve LP problems with simplex tableau.

Its column becomes the pivot column. Step 2: Divide each number in the quantity column by the corresponding number in the X 1 column: 100/2 = 50 for the first row and 240/4 = 60 for the second row. The smaller of these num- Simplex method. Intermediate operations (show/hide details) Pivot row (Row 1): / = Tableau : Base: C b: P 0: Z : Show results as fractions. The optimal solution value is Z = The Two-Phase Simplex Method – Tableau Format Example 1: Consider the problem min z = 4x1 + x2 + x3 s.t. 2x1 + x2 + 2x3 = 4 3x1 + 3x2 + x3 = 3 x1, x2, x3 >= 0 There is no basic feasible solution apparent so we use the two-phase method. The artificial variables are y1 and y2, one for each constraint of the original problem.

Simplex Method Maximization Problems Step 1: Set up simplex tableau using slack variables (Lesson 4.1, day 1) Step 2: Locate Pivot Value Look for most negative indicator in last row. For the values in this column, divide the far right column by each value to find a “test ratio.” Simplex Tableau The simplex tableau is a convenient means for performing the calculations required by the simplex method. Setting Up Initial Simplex Tableau Step 1: If the problem is a minimization problem, multiply the objective function by -1.

This is the origin and the two non-basic variables are x 1 and x 2.To move around the feasible region, we need to move off of one of the lines x 1 = 0 or x 2 = 0 and onto one of the lines s 1 = 0, s 2 = 0, or s 3 = 0.
