In: Operations Management
Decision Variables:
Let,
Number of Black and White Picture chemical = x1
Number of Color Photo chemical = x2
Objective Function:
The objective here is to minimize the cost of production.
Cost for Black and White is $2,500 per ton
Cost of Color photo chemical = $3,000 per ton.
So the objective function is:
MINIMIZE 2500*x1 + 3000*x2
Constraints:
At least 30 tons of black and white and 20 tons of color chemical must be produced.
x1 >= 30
x2 >= 20
The total number of chemicals must be at least 60 tons.
x1 + x2 >= 60
Number of chemicals cant be fractional.
x1, x2 = integer
Putting in Excel:
Solver Parameters:
Optimal Solution:

20 |
Black and White Chemicals = 40
Color chemicals = 20
Lowest Cost = $160000
