FAST replacement - with maintenance reduced to the lowest point consistent with safety - is the theme presented by this author. On the basis of TVA fleet policies, he argues the case for fast replacement. He follows up with an analysis of the question: when is fast replacement fast?
He cites high job-shop overhead costs, which makes unit replacement of accessories, and early replacement of vehicles, economically inviting - except for large, special trucks. He proposes mass-production overhaul of components on large-volume, nationwide basis.
He emphasizes the need for balanced component designing, looking forward to a future when all components in one vehicle will wear out together.
