Data Source
|
|---|---|---|
|
Assembly name
|
Assy
|
For an independent block, the name specified on the General page in the Calculation Properties window. For a linked block, the name of the linked item.
|
|
Availability
|
A
|
The availability of the block based on results from the most recent RBD calculation.
|
|
Capacity
|
Capacity
|
The percent of capacity that the block contributes to the operation of the system. This value is specified on the General page in the Calculation Properties window.
|
|
Component Identifier
|
Component
|
The identifier assigned to the block to identify it in different phases of a phase diagram. Phase diagrams are described in Phase Diagrams. This identifier is applicable only when phase calculations run. For more information, see Component Identifiers.
|
|
Description
|
---
|
For an independent block, the description specified on the General page in the Calculation Properties window. For a linked block, the description of the linked item.
|
|
Duration
|
Duration
|
The amount of time that the system operates in the given phase. A duration value is assigned only to phases in phase diagrams.
|
|
Expected failures
|
Exp Fail
|
For an independent block, this is the failure rate or MTBF (mean time between failures) specified for the block on the Failure page in its Calculation Properties window. For a data-linked block, this is the failure rate for the linked item.
|
|
Failure properties
|
FR, or MTBF
|
The FR (failure rate), MTBF (mean time to failure or mean time between failure, depending on whether the block is repairable).
|
|
Identifier
|
Identifier
|
The unique identifier assigned to the block. This identifier appears for Identifier in the RBD Blocks table or on the General page in the block’s Calculation Properties window.
|
|
Mean availability
|
Mean Avail
|
The average availability of the block at each time interval.
|
|
Mean capacity
|
Mean Capacity
|
The average capacity of the system during each time interval.
|
|
Part number
|
PN
|
For an independent block, the part number entered on the General page in the Calculation Properties window. For a block linked to an assembly or part in the System Tree Items table or Parts Table, the part number assigned to the linked assembly or part.
|
|
Quantity
|
Qty
|
The quantity entered on the Redundancy page on the block’s Calculation Properties window to indicate the number of units present in the system (online).
|
|
Quantity required
|
Qty Req
|
The quantity entered on the Redundancy page in the block’s Calculation Properties window to indicate the number of units required for system operation.
|
|
Reference designator
|
Ref Des
|
For an independent block, the reference designator entered on the General page on its Calculation Properties window. For a block data linked to an assembly or part in the System Tree Items table or Parts Table, the value shown is the reference designator for the linked assembly or part.
|
|
Reliability
|
R
|
The reliability calculated for the block.
|
|
Repair properties
|
MCT
|
For an independent block, the MCT (mean corrective time) specified on the Failure page in its Calculation Properties window. For a data-linked block, the MTTR (mean time to repair) of the item to which it is linked.
|
|
Total downtime
|
DownTime
|
The cumulative downtime expected during each time interval.
|
|
Unavailability
|
Q
|
The unavailability calculated for the block.
|
|
Unreliability
|
F
|
The unreliability calculated for the block.
|
|
Wait time – labor
|
Wait Time-Labor
|
The total expected waiting time for the repair resource to arrive and perform maintenance during each time interval.
|
|
Wait time – spares
|
Wait Time-Spares
|
The total expected waiting time to receive spares during each time interval.
