Overview#

A Schedule is used to optimize the individual Resource processing sequence for one or more Areas, based on the Facility model as given by the master data configuration, subject to a set of constraints and trying to maximize or minimize some key performance indicators as specified by the user.

Note that each Resource must be configured to use either Dispatching or Scheduling. In order to use the Scheduling functionality, it is necessary to follow the following steps:

1. Create the Schedule object.
2. Assign the Schedule object to one or more Areas, where it is intended to be applied.
3. Set the desired Resources to Scheduling mode, and make sure that they have the Resource Process Time defined, and when applicable, the Setup and Setup Matrix.
4. Create one or more Schedule Scenarios.
5. Generate (optimize) one or more Schedule Scenarios according to some Scheduling Optimization Criteria.
6. See the Schedule Scenario Scheduling KPIs and release one Schedule Scenario.
7. Execute the Schedule.

The Schedule Engine works as a two step optimization process as described in the next picture.

At the core of the Schedule object is a set of Schedule Scenario Jobs which contain all the planned information. A Schedule Scenario Job follows the state model described in the next figure.
