Primary and Standby Example

Purposes

The purposes of this example is to illustrate the following options in SCT:

  1. State Upon Repair: Default ON unless SCT overridden
  2. Activate a block if any item from these associated maintenance group(s) goes down
  3. Deactivate a block if any item from these associated maintenance group(s) is restored

Description

Consider a system shown in Figure below:

Primary and Standby.png

Block P is the primary device. It belongs to maintenance group P.

Block S is the standby device. It has state change triggers. The initial state is OFF. If Block P goes down, then activate this block; if Block P is restored, then deactivate this block.

Both Block P and S have Weibull distribution with Beta=1.5 and Eta=100 for reliability and repair action.
