SYSTEM FOR CALCULATING THE NUMBER OF DISTRIBUTION COURSES AND METHOD FOR CALCULATING THE NUMBER OF DISTRIBUTION COURSES

摘要

The necessary number of delivery routes is accurately calculated corresponding to properties of an area. A system 100 for calculating the number of delivery routes calculates the necessary number of delivery routes when creating a plurality of delivery routes on which a staff delivers articles sequentially from a base to respective circular-visiting points in an area including the base and the circular-visiting points and returns to the base. A first average value calculating unit 310 calculates average value D of round-trip travel time between the base and the respective circular-visiting points, considering only circular-visiting points where round-trip travel time between the base and respective circular-visiting point amount to a predetermined rate or less when respective round-trip travel time are selected in order of increasing time, with the exception of the other circular-visiting points.
