Zusammenfassung:To provide a technology that does not require advance preparation of a scenario regarding an amount of operation.SOLUTION: A driving support device comprises: a simulator construction unit that constructs a value prediction simulator for the state variable of a target using a plurality of performance data collected from a target and inputting a value of an operation variable of the target and a value of an environment variable of the target; a first scenario creation unit that uses the value of the operation variable to form an operation variable scenario representing the value of the operation variable that can be realized in the target; a second scenario forming unit that forms a state variable scenario representing the value of the state variable when the value of the operation variable and a predetermined value of the environment variable are input to a simulator using the simulator, the operation variable scenario and the predetermined value of the environment variable; and an optimization unit configured to calculate an optimal value of an operation variable to bring the value of the target state variable closer to a target value by employing the operation variable scenario and the state variable scenario when a predetermined value of the environment variable and a target value of the state variable are given.SELECTED DRAWING: Figure 4 【課題】操作量に関するシナリオの事前準備を不要とする技術を提供すること。【解決手段】対象から収集した複数の実績データを用いて、対象の操作変数の値と前記対象の環境変数の値とを入力として対象の状態変数の値予測シミュレータを構築するシミュレータ構築部と、操作変数の値を用いて、対象で実現可能な操作変数の値を表す操作変数シナリオを作成する第1のシナリオ作成部と、シミュレータと、操作変数シナリオと、与えられた環境変数の所定値とを用いて、操作変数の値と記環境変数の所定値とをシミュレータに入力したときの状態変数の値を表す状態変数シナリオを作成する第2のシナリオ作成部と、環境変数の所定値と状態変数の目標値とが与えられたときに、操作変数シナリオと状態変数シナリオとを用いて、対象の状態変数の値を目標値に近付けるための操作変数の最適値を算出するように構成されている最適化部と、を有する。【選択図】図4
