Design assistance system and design assistance method

A design assistance method performed by an information processing apparatus including a control apparatus and a storage apparatus that stores a quality prediction model that receives input of data representing a state and data representing a process to be performed on a raw material in the state, and outputs data representing quality of a deliverable obtained from the raw material after the process,

• the control apparatus executing:
• a state distribution model construction process of acquiring information about a state at each position in a spatial area in a case where a process has been performed on a raw material distributed in the spatial area, calculating a value representing state ununiformity in the spatial area on a basis of each acquired piece of information, and, on a basis of the calculated value representing the ununiformity, and data defining the process, generating a state distribution model that receives input of a process design parameter which is data defining a process to be performed on a raw material existing in a spatial area, and output data representing state ununiformity in the spatial area after the process;
• a state distribution model execution process of setting a value of the process design parameter, and acquiring a value of data representing state ununiformity in a spatial area related to the process design parameter to which the value has been set, after a process represented by the set value of the process design parameter, by inputting the set value of the process design parameter to the state distribution model;
• a manufacturing quality prediction process of identifying a plurality of possible states in the spatial area from the acquired value of the data representing the state ununiformity in the spatial area, and acquiring, for each of the identified states, a quality parameter of a deliverable obtained from the raw material after the process represented by the set value of the process design parameter by inputting, for the state, each piece of data representing the state and the set value of the process design parameter to the quality prediction model;
• and
• a parameter exploration process of changing the set value of the process design parameter, on a basis of each of the acquired quality parameters, such that the quality of the deliverable obtained from the raw material falls within a predetermined range.
