Apparatus and methods are provided for automated movement of an umbrella. The top rod is inserted in an insert hole of the housing, having a wall bored with a cut recess. A position setpoint corresponding to a clutch torque and disposed between the raster values of the position raster is calculated, and the actuator parts are positioned relative to each other at a raster value of the position raster that is adjacent to the position setpoint. The virtual partition may be stored within the virtual data object according to a virtual data format. The support system simplifies removal and installation of the auxiliary power unit from and into the aircraft’s tailcone. A workflow engine may instantiate the process model for execution, including associating an instance of the task with a user of the human users, the task instance including instance-specific data associated with completing the execution.
