TTKL collects basic information on running times and transport distances necessary for determining the routes and provides them to TMT. TMT then calculates the transport volume everyday based on parts information, the production plan and container sizes, and then determines the routing and scheduling plan using an optimization system for operations management. Based on these results, TTKL prepares the stowage plan, truck diagram and the schedule of the host terminal. In actual operation, a guide containing the driver check sheet, route code card, terminal card and container label is prepared by TTKL’s operation manager for easy understanding of the operational plan. The operation manager assigns a driver to each route, and registers the route information in a geographic information system
