means permitting removal of one box at one end of the
pile of ?ll tabs. By advancing some of these deliveries to
a slack period the dispatcher may. balance his daily delivery
requirements to his operating truck capacity. It is also
evident that the dispatcher may manipulate this analog to
suit other special conditions which may arise, such as truck
breakdown, for example.
As weather units are accumulated day by day during
