Block Summary

The Block Summary worksheet in the Simulation Results Explorer displays a summary of the simulation results for each block.

• Block Name: The name of each block in the diagram.

• RS FCI: The ReliaSoft Failure Criticality Index for each block. This is a relative index showing the percentage of times that a failure of the block caused a system failure (i.e., the number of system failures caused by the block divided by the total number of system failures). Note that this relates only to failures; it does not include every event that could bring the system down (such as routine maintenance).

• RS DECI: The ReliaSoft Downing Event Criticality Index for each block. This is a relative index showing the percentage of times that a downing event of the block caused the system to go down (i.e., the number of system downing events caused by the block divided by the total number of system downing events).

• RS DTCI: The ReliaSoft Downtime Criticality Index for each block. This is a relative index showing the contribution of each block to the system's downtime (i.e., the system downtime caused by a particular block divided by the total system downtime).

• Mean Av. (All Events): The mean availability of all downing events for each block during the simulation.

• Mean Av. (w/o PM, OC & Insp.): The mean availability of all downing events for each block, not including preventive or inspection tasks, during the simulation.

• Expected # of Failures: The total number of failures expected to occur during the simulation for each block.

• 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 may be included in system reliability calculations.

• System Downing Events: The number of events for each block that caused the system to go down during the simulation.

• 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.

• Number of CMs: The total number of corrective tasks performed on each block during the simulation.

• CM Downtime: The total amount of time that each block was down (i.e., not operational) due to corrective maintenance during the simulation.

• Number of Inspections: The total number of inspections performed on each block during the simulation.

• Inspection Downtime: The total amount of time that each block was down (i.e., not operational) due to an inspection during the simulation.

• Number of PMs: The total number of preventive tasks performed on each block during the simulation.

• PM Downtime: The total amount of time that each block was down (i.e., not operational) due to a preventive task during the simulation.

• Number of OCs: The total number of on condition tasks performed on each block during the simulation.

• OC Downtime: The total amount of time that each block was down (i.e., not operational) due to an on condition task during the simulation.

• Throughput: The total number of units that were processed/produced by each block during the simulation time. The throughput will be calculated only if you selected to run a throughput simulation on the Analysis Settings page of the diagram control panel.

• Total Cost: The total cost for each block, which is based on the task, crew and spare part pool costs.
