Ranking Functions

A ranking function ranks the specified items based on the specified criteria. Ranking functions are usually used prior to making an assignment determination on a specific set of drivers or vehicles.

All ranking functions require an association with a predefined ranking algorithm, in order to determine custom criteria for ranking. For more information, see Ranking Algorithms. Ranking functions are only available from within a driver assignment scenario.

To add a ranking function to your driver assignment scenario, select Functions - Ranking from the Available Variables, Functions, and Constants drop down and then double-click the ranking function you want to add. Since the ranking function requires an association with a ranking algorithm, a box with an asterisk (*) will appear in the step type. Replace the asterisk box with a ranking algorithm the same way you would replace an item in a calculated variable or algorithm step.

The ranking algorithms are available from the Available Variables, Functions, and Constants drop down under Algorithms - Rank Driver and Algorithms - Rank Vehicle.
