1. A method implemented by a computer programmed as a rule generation apparatus for iterative construction of an explanatory model of an industrial process, the method comprising: determining, by a processor of the computer, based on experimental data obtained from the industrial process, a rule in the explanatory model that explains at least a part of the experimental data; displaying the determined rule to a user and allowing the user to modify the rule; determining a set of new experiments for evaluating the rule; conducting the determined new experiments to obtain corresponding results; calculating at least one quality indicator that indicates a quality of the determined rule based on the corresponding results of the experiments; and determining whether the at least one quality indicator satisfies predetermined conditions for including the rule in the explanatory model of the industrial process.
