What is a key advantage of finite loading over infinite loading?
Explanation
The main difference between finite and infinite loading is the consideration of capacity. Finite loading creates a feasible schedule by only assigning work up to a resource's capacity, whereas infinite loading assigns all work to meet due dates, which can result in an overloaded and unachievable schedule.
