Abstract
Engineers typically make plant machinery’s economic replacement decisions. Such decisions involve cost analysis, which allow determining when the current machine is to be replaced with a new one. A manager’s job may be to suggest when such analysis should be conducted, especially on older machines, and when production changes occur.
