To select an operation mode appropriately in a ship power system.SOLUTION: An operation mode selection device is a device which selects an operation mode of a ship power system including one or a plurality of generators and one or a plurality of batteries. The operation mode is determined through at least the number of generators to be driven, a selection of a generator to be driven, a load sharing ratio between the generator and the battery, and a selection as to whether to charge/discharge the battery. The device comprises a reinforcement learning unit which selects the operation mode by: using, as an environmental element, an output of a model of a ship power system that operates on the basis of predetermined settings pertaining to a load of the ship power system; using, as a behavior element, at least the number of generators to be driven, the selection of a generator to be driven, a load sharing ratio between the generator and the battery, and the selection as to whether to charge/discharge the battery; using, as a compensation element, a fuel cost and a lifecycle cost pertaining to a component lifetime; and performing reinforcement learning on a software agent.SELECTED DRAWING: Figure 1

    【課題】船舶の電源システムにおける運転モードを適切に選択する。【解決手段】運転モード選択装置は、1または複数の発電機と1または複数のバッテリとを備える船舶用電源システムの運転モードを選択する装置であって、運転モードは、少なくとも、発電機の運転台数と、運転する発電機の選択と、発電機とバッテリとの負荷分担率と、バッテリの充放電の選択とによって定められ、船舶用電源システムの負荷に係る所定の設定に基づいて動作する船舶用電源システムのモデルの出力を環境要素とし、少なくとも、発電機の運転台数と、運転する発電機の選択と、発電機とバッテリとの負荷分担率と、バッテリの充放電の選択とを行動要素とし、燃料費と部品寿命に係るライフサイクルコストを報酬要素として、ソフトウェアエージェントを強化学習することで、運転モードを選択する強化学習部を備える。【選択図】図1
