摘要:
A transportation schedule planning support system receives an order of one or more types of products which requires a use-by date control, and transports the products from one or more stock-carrying bases to one or more delivery destinations. In the system, a user previously registers a transportation route candidate from a stock-carrying base to each delivery destination adoptable as a solution, as a base group. A necessary use-by date for a product to be delivered next is determined based on an actual delivery to each delivery destination. The number of vehicles allocatable to a transportation at each base according to a vehicle type, and a vehicle type not used in each base group are added to a restriction condition. A mixed integer programming is applied using an expected obtainable profit obtained by delivering each product as an objective function.

The present disclosure presents a wheel diameter variation-detecting device capable of properly detecting relative variation in diameter between a plurality of wheels of a vehicle. The wheel diameter variation-detecting device can detect variation in diameter between a plurality of wheels of a vehicle, can detect rotational speeds of the respective wheels, and can calculate a variation parameter indicative of variation in diameter between the wheels using one of the wheels as a reference wheel, based on a result of comparison between the rotational speed of the reference wheel and that of one of the wheels other than the reference wheel. Further, the wheel diameter variation-detecting device can learn the variation parameter based on a value obtained by averaging a plurality of values of the variation parameter obtained before the detected travelled distance reaches a predetermined distance.
