Explanation Procedure used: “ Big M Method: Introducing Slack, Surplus, and Artificial Variables to Form the Modified Problem. Step 1: - If any problem constraints have negative constants on the right side, multiply both sides by − 1 to obtain a constraint with a nonnegative constant. (If the constraint is an inequality, this will reverse the direction of the inequality.). Step 2: Introduce a slack variable in each − 1 constraint. Step 3: Introduce a surplus variable and an artificial variable in each ≤ constraint. Step 4: Introduce an artificial variable in each = constraint. Step 5: For each artificial variable a i , add M a i ; to the objective function. Use the same constant M for all artificial variables”. Calculation: The given linear programming problem is: Maximize P = 2 x 1 +5 x 2 subject to x 1 + 2 x 2 ≤ 18 2 x 1 + x 2 ≤ 21 x 1 + x 2 ≥ 10 x 1 , x 2 ≥ 0 Introduce slack, surplus, and artificial variables and obtain the modified problem: x 1 + 2 x 2 + s 1 = 18 2 x 1 + x 2 − s 2 = 21 x 1 + x 2 − s 3 + a 1 = 10 − 2 x 1 − 5 x 2 + M a 1 + M a 2 + P = 0 Write the preliminary simplex tableau for the modified problem, and find the initial simplex tableau by eliminating the M's from the artificial variable columns: Preliminary simplex x 1 x 2 s 1 s 2 s 3 a 1 a 2 P [ 1 2 1 0 0 0 0 0 18 2 1 0 − 1 0 0 0 0 21 1 1 0 0 − 1 1 0 0 10 − 2 − 5 0 0 0 M M 1 0 ] ( ( − M ) R 2 + ( − M ) R 3 + R 4 → R 4 ) Initial simplex tableu ~ s 1 a 1 a 2 P [ 1 2 1 0 0 0 0 0 18 2 1 0 − 1 0 0 0 0 21 1 1 0 0 − 1 1 0 0 10 − 3 M − 2 − 2 M − 5 0 M 0 0 M 1 − 31 M ] ( R 1 − R 3 → R 1 R 2 − 2 R 3 → R 2 R 4 + ( 3 M + 2 ) R 3 → R 4 ) ~ [ 0 1 1 0 1 − 1 0 0 8 0 − 1 0 − 1 2 − 2 0 0 1 1 1 0 0 − 1 1 0 0 10 0 M − 3 0 M − 3 M − 2 3 M + 2 M 1 − M + 20 ] ( R 2 2 → R 2 ) ~ [ 0 1 1 0 1 − 1 0 0 8 0 − 0
