Answer: Profitably fill unused capacity by using complex mathematical systems.
Step-by-step explanation:
Yield Management refers to an revenue management style that aims to draw out as much profit for the company from a fixed resource or inventory. It aims to sell the right product at the best price to the a customer at the rightful time it is required.
