Delivery matching system and delivery matching method

A delivery matching system allocating an additional order for delivering a cargo to an existing delivery route by a computer including a processor and a memory,

• wherein the processor
• performs learning of a predetermined learning model using an index value for a selected solution, which is a Pareto solution selected by a user among Pareto solutions based on a predetermined index, obtained from past input data including a combination of a delivery route and an additional delivery order, as training data,
• inputs current input data including the combination to the learned predetermined learning model, and calculates a prediction index weight vector for each index of the Pareto solution,
• specifies a Pareto solution in which a degree of similarity with the prediction index weight vector satisfies a predetermined condition, among the Pareto solutions, and
• outputs the specified Pareto solution.
