    Abstract: A system performs either inference using a first model or inference using a second model and a third model according to accuracy of at least one model of the first to third models and, upon the inference, generates or updates recipe properties data that is data indicating an association between a manufacturing method recipe for a material and a material property/properties. The first model is a model to which a manufacturing method recipe dataset indicating a manufacturing method recipe is input and from which a material properties dataset indicating a material property/properties is output. The second model is a model to which a material characteristics dataset indicating a material characteristic(s) is input and from which a material properties dataset is output. The third model is a model to which a manufacturing method recipe dataset is input and from which a material characteristics dataset is output.
