Indian Institute of Technology (IITs) delivers three courses: Mechanical Engineering, Electrical Engineering, and Computer Science. These products have the following resources requirements:
Course | Cost/Unit | Labour-Hours/Unit | |
Mechanical Engineering | $7.00 | 2 | |
Electrical Engineering | $10.00 | 3 | |
Computer Science | $35.00 | 5 |
IIT has a daily teaching budget of $5,000.00 and a maximum
budget of 800 hours of labour. Selling prices are $15.00, $25.00
and $55.00 respectively. Maximum daily customer demand for Computer
Science course is 100 units. The University desires to know the
optimal product mix that will maximize profit. Formulate a linear
programming model for this problem.
As the university wants to maximize the profit we will formulate a maximization problem which maximises the revenue.
Decision Variables:
Let x, y, z are the unit of couses in Mechanical Engg, Electrical Engg and computer science respectively in optimal product mix
Obj Function: Maximise 15*x+25*y+55*z (i.e. Total revenue by selling the courses)
Subject to:
cnstraint1: Daily teaching budget can be owritten as
7*x + 10*y + 35*z <= 5000
constraint2: daily labout hour constraint can be written as
2*x + 3*y + 5*z <= 800
constraint3: maximum demand of computer science course can be formulate as
z <= 100
Constraint4: Non negativity constraint
x > =0, y >= 0, z >= 0
