The number of working teams and the operation capacities at each operation part are shown in Fig. 3,
where the number of working teams at each part is shown in the square brackets. Furthermore, the numbers shown in parentheses represent the capacities of the corresponding flows, including the handling
capacity of cargo flow, and the transmission capacity of information flow. The units of the capacities
of cargo flow and information flow are tons per hour and cargos per hour, respectively. For human flow,
however, the number shown in parentheses represents time taken for labor operations, and its unit is
minutes.
