Review a brief description about how UPS took advantages of business analytics:

UPS$$ On$-$Road Integrated Optimization and Navigation $($ORION$)$ system reorganizes the drivers$$ routes based on each day$$s customers, needs, and packages, and it designs deliveries in a very specific, optimized order. ORION recommends optimized driving routes with all the stops by taking into account UPS business rules, maps, what time drivers need to be at specific locations, and customer preferences. When UPS drivers are on the road, they usually travel at speeds of $2025$ miles per hour. Therefore, every mile reduced equates to a savings of $23$ minutes. Because ORION shortens routes by $78$ miles per day, this savings enables UPS to deliver more packages and reduce costs.

Did UPS apply descriptive, predictive, or descriptive analytics in this case? Briefly explain why.
