PROBLEM TO BE SOLVED: To provide a delivery planning device, delivery planning system, delivery planning method, and program capable of contributing to cost reduction required for delivery of fuel compared with a case without having demand predictive value derivation means, stock predictive value derivation means, and output means.SOLUTION: An output section 26 outputs information according to a solution of an optimization problem that has, as one of constraint conditions, correlation information in which correlation with regulation information is formulated. The regulation information is for regulating a scheduled amount of delivery according to an amount of stock of fuel in demand facilities 16, a predictive value of demand derived by a demand predictive value derivation section 22, a predictive value of stock derived by a stock predictive value derivation section 24, and the number of delivery vehicles for each vehicle type, required for delivering the fuel to the demand facilities 16. The optimization problem is for minimizing an objective function using the number of delivery vehicles as one of variables. |
