A
form of asset replacement
policy that falls into the preventive
replacement class (see figure).
If a system, such as electrical or mechanical, consists of a group of assets (the block), a unit is replaced upon failure and at times T, 2T, 3T... The ages of the assets are not observed and only their failures are known, all units may be replaced periodically independently of their ages in use. Each unit is individually replaced on failure during a specified time interval. Beyond the failure replacement interval, failed units are left idle until a specified number of failures occur, then a block replacement is performed. Attributes Listed below are some of the key attributes of a block replacement policy:
