Scheduling Cleaning Services

The Minte, a housekeeping scale-up from the USA, allows flexible scheduling of cleaning services. These services are assigned creating a schedule for each housekeeper. Housekeepers serve multiple properties spread across a geographical area. This incurs significant travel costs if the schedule is not created in a way that minimizes the distance travelled by housekeeping personnel, having a strong negative impact on unit.
