LockoutZone

The object LockoutZone combines a group of material flow objects. If one of these stations fails, all other stations within the lockout zone stop processing their parts as well. The LockoutZone then controls the failures of all assigned stations. As a result it returns the total availability of the assigned stations.

You can insert more than one LockoutZone into a simulation model. The LockoutZones can overlap, meaning that a station can be assigned to more than one LockoutZone.

You have to define failure profiles for at least one of the stations assigned to the LockoutZone. As soon as one of the stations fails, the LockoutZone stops all processing operations of all assigned stations, meaning it sets their attribute Stopped to true. You can select if the LockoutZone stops the processing operations immediately or when the service arrives.

The stations only start processing parts again after all failures were removed. They then only use up the respective remaining processing time.

You can also determine what happens when the stations start processing parts again by programming a Resume control.

In case one of the stations is paused when the LockoutZone intends to stop, this station does not start or restart processing after the pause is over.

You can assign any of the built-in Material Flow Objects or Fluid Objects to the LockoutZone. For stations you yourself modeled in a Frame, the LockoutZone sets the attribute Stopped of that Frame to true. You then have to model an adequate reaction to the attribute. In addition, you can also add a Worker or the Workerpool.

If the station that triggers the lockout zone is assigned to more than one LockoutZone, all stations of all LockoutZones will be stopped. If the station that triggers the lockout zone is assigned to only one LockoutZone, it only stops the station that you assigned to it.

To add the LockoutZone to your simulation model, click Manage Class Library > Basic Objects > Resources > LockoutZone on the Home ribbon tab.
