Table 6.16 gives the transportation cost inside each facility, the costs between
facilities, and the transportation capacities between facilities, for three time periods.
This example requires a dynamic version of the model for a fixed period.
The 13 departments can be aggregated into 5 department types, and their
characteristics are given in Table 6.17. For each of the three time periods, the
directed flows between departments are shown in Fig. 6.3.
