| 释义 | group replacementgroup replacementa PREVENTIVE MAINTENANCE system which replaces groups of items such as lightbulbs at predetermined intervals, even though they may not all have come to the end of their life. This is done because group replacement can be more cost-effective than the replacement of individual items as they fail, if the cost of replacement units is low and the labour and other costs of replacing them are high. |
