Field Service Schedule Optimization properties

Schedule Optimization general properties

Property

Description

Exit buffer time

Amount of time (in minutes) to add between the end of a task and the travel start of the next. An example of a valid time value is 10.- Type: Integer

  • Default value: 0
  • Location: All > Field Service > Administration > Properties

Qualifier type for schedule optimization

The qualifier type for schedule optimization determines the criteria used to optimize schedules. There are two qualifier types available: "Assignment group" and "Territory."When the Field Service Territory model is enabled, the qualifier type automatically switches to "Territory" and remains fixed. This means that when the Territory model is active, the optimization process focuses on territories instead of assignment groups. For more information, see Enable the Field Service territory model.

  • Default value: Assignment group
  • Location: All > Field Service > Schedule Optimization > Administration > Properties

Number of seconds used for task scheduling resolution

  • Type: Integer
  • Default value: 300
  • Location: All > Field Service > Schedule Optimization > Administration > Properties
