Hi Sir John,
I have confusion on the implication of slack and surplus.
1. Why when the slack is low, the resource could become a binding constraints?
2. What is binding constraints?
3. Which one is good, the slack is low, high or average?Thank you.
Regards,
GraceSlack is the difference between the amount available and the amount actually being used.
A binding constraint is a constraint that is limiting the amount they can produce.
If there is slack in a constraint then it is not binding because they are not using all that is available for purchase. If there is no slack then it is a binding constraint because it is stopping them producing more.
None of them are good or bad on their own!!! It is only a problem when there is no slack.
Have you watched my free lectures on linear programming? The lectures are a complete free course for Paper PM and cover everything needed to be able to pass the exam well.
Hi Sir John,
Thanks for the explanation. I have watched your lectures on linear programming but I have to watch again as I missed out some points.
Regards,
Grace
