Rules for the Appointment Booking System

When preparing a list of possible time slots, the ABS enforces the following rules:

• The offered time slots must equal the availability of the personnel for a service region.
• The offered time slots must match the personnel with the required skills. You can enforce this rule with the Use Assignment Manager scheduling parameter.

  NOTE:  Assignment Manager scores do not affect the order or ranking of the returned time slots. The scores determine only whether an employee is eligible to own an activity.

• Time slots must meet other constraints. For example, an engineer must never perform more than 4 installations in a day. Other constraints for service activities might meet business or union requirements.
• Activities can extend over multiple days.
• The Optimizer and ABS treat activities that cross between the end of the Optimizer horizon and the beginning of the ABS period as locked.
