<p><P>PROBLEM TO BE SOLVED: To provide a physical distribution network evaluation method that can display and evaluate physical distribution network measures against future emergencies. <P>SOLUTION: The physical distribution network evaluation method uses a storage part for storing physical distribution flows of nodes, physical distribution flows of arcs, a recovery scenario, and activity criteria and activity states of the nodes or arcs, and a processing part for performing various information processing. In the event that an optional node fails and becomes inactive, the processing part first, in stages of node recovery, stores in the storage part activity state determination results of each node and arc according to the physical distribution flows of each node and arc and the activity criteria stored in the storage part, and calculates physical distribution flows of each displayed node and arc according to the physical distribution flows of the nodes, the physical distribution flows of the arcs and the recovery scenario in the storage part; then displays active nodes and arcs according to the stored activity state determination results; evaluates the physical distribution flows of each node according to the calculated physical distribution flows of the node; and displays the evaluation results. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
