1. An assistance method comprising steps of:
acquiring information related to a process or a reduced system when the process to be performed in a plant is performed in the reduced system with a smaller scale than the plant;
automatically generating at least a part of a model for predicting a process to be performed in the plant, or an intermediate system with a scale between the plant and the reduced system, based on a relationship between systems when the process is performed in a plurality of systems of different scales, from the information using an AI (artificial intelligence), wherein the AI learns a relationship between systems based on (i) information related to a plurality of systems of different scales, (ii) information of a process when the process is performed in the reduced system or information of the model for predicting a process to be performed in the reduced system, and (iii) information of the model for predicting the process to be performed in the plant or the intermediate system; and
determining an operation condition of the plant based on the model to provide control assistance for the plant.
