6.1.5 Use of ActivitySpec Properties— The ActivitySpec part of the ActivityOption and ActivityForecast are
provided to allow implementations to extend the specifications of activities for specific implementations. The names
and value types of properties included in these ActivitySpec structure are not part of the standard.

6.1.6 SchedulingManager Interface
Module: Scheduling
Interface: SchedulingManager
Inherited Interface: ComponentManager
interface SchedulingManager : FactoryOperations::ComponentManager {
Description: The SchedulingManager provides the concrete interfaces that support the registration and
control of the Scheduling Component and enable access to the Dispatcher and Scheduler
interfaces.
Exceptions:
/* An attempt was made to request an activity for a resource that is not found within the factory data available to this
SchedulingManager. */
exception ResourceNotFound {
AbstractIF::Resource requestedObject;};
/* An attempt was made to request an activity for a material group that is not found within the factory data available
to this SchedulingManager. */
exception MaterialGroupNotFound {
AbstractIF::MaterialGroup requestedObject;};
/* An attempt was made to request an activity for a durable that is not found within the factory data available to this
SchedulingManager. */
exception DurableNotFound {
DurablesManagement::Durable requestedObject;};
Published Events:.
/* The ActivityListAvailable event is published by the Scheduling Component to notify event subscribers that a new
ActivityList containing changes is available. The generation of ActivityListAvailable events is controlled as an
implementation specific configuration choice. */
ActivityListAvailable
/* The ForecastListAvailable event is published by the Scheduling Component to notify event subscribers that a new
Forecast is available. ForecastList generation is potentially a compute-intensive operation which may benefit from
event notification when an updated forecast is available. The generation of ForecastListAvailable events is
controlled as an implementation specific configuration choice. */

be represented by an activity list with only one activity option. The ActivityOptions returned by this operation may
be ProductionActivity, MaintenanceActivity or DoNothing ActivityTypes. Although Resources are typically
immobile (such a Equipment), some Resources may also be subject to TransportActivities. */
