In a process flow, a task sequence is a series of tasks that are performed together and assigned to a task executer,
00:10
such as an Operator or a Transporter.
00:13
Task sequences are essential for modeling and controlling the behavior of task executers in your model,
00:19
enabling an accurate simulation of both simple and complex processes.
00:24
Here, review an example of a simple task sequence, where items arrive through the Source,
00:30
enter the first Queue, and are then transported by an Operator to the Conveyor.
00:37
You can easily set this up directly in your model using 3D logic by connecting the Queue to the Conveyor,
00:45
center-connecting the Queue to the Operator, and then, in Queue Properties, selecting Use Transport.
00:53
Watch as the model is Reset and Run.
00:56
While this setup does work, alternatively, you can create a task sequence in your process flow to achieve this same result,
01:03
but that also offers increased flexibility and more options for customization.
01:08
With the 3D connectors removed, begin in the ProcessFlow.
01:13
In this scenario, open the Quick Library to add an Event-Triggered Source.
01:18
Then, next to the Source, click the Sampler.
01:23
In the Model, select Queue1, and in the drop-down, select Queue1: On Entry.
01:30
Next, in Source Properties, add a Label Name for the token, noting that labels are case sensitive.
01:37
Here, the name “item” is used.
01:40
Then, set the Operation to assign.
01:44
Back in the ProcessFlow, add a connector from the Source, and then, in the Quick Library, select Create Task Sequence.
01:53
In the Create Task Sequence Properties, next to Task Executer / Dispatcher, click the Sampler, and then, in the Model, select Operator1.
02:05
In the ProcessFlow, add a Load activity to the Create Task Sequence activity to create an activity block.
02:12
Open the Load Quick Properties to view the default values.
02:17
If you look back at the Create Task Sequence and Source properties, you see that the task sequence and item are already assigned,
02:24
and then it will pick up at the Queue, or Station, which is the Item Container, so you can leave all of the defaults here.
02:31
Next, add an Unload activity to the ProcessFlow.
02:36
In the Quick Properties, leave the default values for the Executer and Item fields,
02:41
and for the Station field, click the Sampler.
02:45
In the Model, select EntryTransfer3 on the Conveyor.
02:49
In the ProcessFlow, add a Finish Task Sequence activity, and then a Sink to complete the sequence.
02:57
Reset and Run the model, and you can see that the Operator takes the items from the Queue and then unloads the items at the Conveyor.
03:05
Now you can create a task sequence to transport a single item using a single operator in your process flow.
