Block Summary
The Block Summary worksheet for PFS diagrams displays a summary of the simulation results for each process block. The values shown are averages of the results of all of the simulations.
Note: You can customize the order in which the blocks are displayed in the simulation results by right-clicking inside the diagram sheet and choosing Set Block Order on the shortcut menu. You will need to resimulate the diagram for the new block order to be shown in the results.
- Block Name: The name of each block in the diagram.
- Block Description: The description of each block in the diagram. This is displayed only if Show Block Description is selected on the ribbon.
- Block Downtime: The total amount of time that each block was down (i.e., not operational) during the simulation.
- Block Uptime: The total amount of time that each block was up (i.e., operational) during the simulation.
- Expected # of Failures: The total number of failures expected to occur during the simulation for each block.
- Failure Downtime: The total amount of time that each block was down (i.e., not operational) due to failures during the simulation.
- Expected # of OFF Events by Trigger: The total number of events where the block is turned off by state change triggers. An OFF event is not a failure but it does affect the throughput results of the diagram.
- OFF by Trigger Time: The total amount of time that each block was OFF due to state change triggers.
- For each of the four classes of tasks (i.e., corrective,
preventive, on condition and inspection), the following information
is presented with regard to tasks performed during the simulation
time for each block:
- Number of [Task Class]: The total number of tasks of this class performed on the block during the simulation.
- [Task Class] Downtime: The total amount of time that the block was down (i.e., not operational) due to tasks of this class during the simulation.
- Total Cost: The total cost for each block, which is based on the block consequential costs (for failure, downtime and uptime) and the task, crew and spare part pool costs.
