Linear programming -> system constraints
- Understanding the concept
- Their economic value
- Modelling
Overlapping ideas:
- Critical path in project management
- The Goal by Goldratt
EXAMPLE
Airport has L long haul Flights and S short haul Flights. They are going to take off .
Now we have a simple linear model:
Goal: maximize revenue
Revenue = $ 500L + $100S
Constrains:
Arrivals: L + S <= 6
Maintenance: 4L + S <= 5
Airplane Staffing: 2L + S <= 9
Solution:
Excel -> Data -> solver
- Set Target Cell
- Check “Max:
- By Changing Cell
- Subject to the constrains: Integers, non-zero, Constraints for arrivals, maintenance, staffing
