Explanation / Answer

A manager at an Oil company wants to find the optimal mix of two blending processes.

Profit per operation

Process P1 = $4000

Process P2 = $5000

Maximum availability of Crude Oil

Grade A = 500 units

Grade B = 400 units

Minimum demand for gasoline

X = 300 units

Y = 200 units

Decision variables

X1 = No. of operations of P1

X2 = No. of operations of P2

Constraints

6X1 + 5X2 < 500

4X1 + 6X2 < 400

6X1 + 5X2 > 300

9X1 + 5X2 > 200

X1, X2 > 0

Objective function

Maximize Z = 4000X1 + 5000X2

Process Input Crude Oil Output Gasoline Grade A Grade B X Y P1 6 4 6 9 P2 5 6 5 5
