Abstract
Claims
1. A delivery planning device comprising: a vehicle probability model that has been trained to output a vehicle probability, which is the probability that two delivery destinations will be delivered by the same vehicle, when two delivery destinations are input; and a cost calculation unit that inputs a first delivery destination and a second delivery destination into the vehicle probability model, obtains the vehicle probability output from the vehicle probability model, and calculates the delivery cost between the first delivery destination and the second delivery destination based on the obtained vehicle probability.
2. The delivery planning device according to claim 1, wherein the cost calculation unit corrects the delivery cost between the first delivery destination and the second delivery destination to be smaller if the acquired probability of the vehicle is equal to or greater than a predetermined first threshold, and corrects the delivery cost between the first delivery destination and the second delivery destination to be larger if the acquired probability of the vehicle is less than or equal to a second threshold which is smaller than the first threshold.
3. The delivery planning device according to claim 1, further comprising: a cost calculation unit that calculates the delivery costs between two different delivery destinations to generate a delivery cost table; and a delivery plan calculation unit that, based on the delivery cost table, calculates one or more delivery destinations to be delivered by the same vehicle and one or more delivery destinations to be delivered by different vehicles, and generates a first delivery plan.
4. The delivery plan calculation unit modifies the first delivery plan based on predetermined constraints and generates a second delivery plan, as described in claim 3.
5. The delivery planning device according to claim 4, further comprising a delivery planning display unit that displays a delivery planning map capable of distinguishing points of agreement and / or differences between the first delivery planning and the second delivery planning.
6. The delivery planning device according to claim 1, further comprising a learning execution unit that performs machine learning of the vehicle probability model using training data which includes at least information indicating whether the two delivery destinations have been delivered by the same vehicle in the past.
7. A delivery planning method comprising: inputting a first delivery destination and a second delivery destination into a vehicle probability model that has been trained to output a vehicle probability, which is the probability that two delivery destinations will be delivered by the same vehicle, given two delivery destinations as input; obtaining the vehicle probability output from the vehicle probability model; and calculating the delivery cost between the first delivery destination and the second delivery destination based on the obtained vehicle probability.
8. A delivery planning program that causes a computer to input a first delivery destination and a second delivery destination into a vehicle probability model that has been trained to output a vehicle probability, which is the probability that two delivery destinations will be delivered by the same vehicle, when two delivery destinations are input; obtain the vehicle probability output from the vehicle probability model; and calculate the delivery cost between the first delivery destination and the second delivery destination based on the obtained vehicle probability.
