To solve problems that delivery plans are often not realistic in spite of detailed delivery planning with a large amount of system development cost, as in a simulation based delivery planning, loading capability is calculated based on the volume and weight of conventional loads. However, in practical delivery service, it often happens that some loads can not be loaded on a vehicle, or a shortest delivery route originally planned is congested due to a traffic jam or accident, causing the original plan to be unrealistic.
This delivery planning system is equipped with a loading decision means 10 that offers solution in more than one group for which a derivery vehicle is assigned for a combination of loads of more than one delivery destinations and that determines whether or not a load can be loaded and the loading rate, and a cost minimum solution selecting means 11 which sets a shortest delivery route for each group of the possible solutions obtained according to simplified map information and which selects a cost minimum solution from possible solutions after cost calculation based on the delivery vehicle unit price and the delivery route.
