Method for manufacturing or machining a product by means of a production system, wherein a) differently detailed, digital structural statements about a structure of the product or of a precursor and digital machining statements about a machining process for the product or for the precursor are read in, b) the structural statements are checked to determine whether a respective structural statement is provided with further detail by a respective other structural statement, c) multiple machining sequences (BS1, BS2) for the product are generated from the structural statements and machining statements such that a structural statement comprising a first machining sequence is provided with further detail by a structural statement comprising a second machining sequence, d) the first machining sequence is transmitted to a first planning module and the second machining sequence is transmitted to a second planning module, e) the first planning module uses the first machining sequence to generate a first action sequence as a first planning result, the second planning module uses the second machining sequence, and takes into consideration the first action sequence, to generate a second action sequence as a second planning result, wherein the first action sequence is refined by the second planning module when generating the second action sequence, f) the action sequence generated by the second planning module is used to generate and output control signals for controlling the production system. a) differently detailed, digital structural statements about a structure of the product or of a precursor and digital machining statements about a machining process for the product or for the precursor are read in, b) the structural statements are checked to determine whether a respective structural statement is provided with further detail by a respective other structural statement, c) multiple machining sequences (BS1, BS2) for the product are generated from the structural statements and machining statements such that a structural statement comprising a first machining sequence is provided with further detail by a structural statement comprising a second machining sequence, d) the first machining sequence is transmitted to a first planning module and the second machining sequence is transmitted to a second planning module, e) the first planning module uses the first machining sequence to generate a first action sequence as a first planning result, the second planning module uses the second machining sequence, and takes into consideration the first action sequence, to generate a second action sequence as a second planning result, wherein the first action sequence is refined by the second planning module when generating the second action sequence, the second planning module uses the second machining sequence, and takes into consideration the first action sequence, to generate a second action sequence as a second planning result, wherein the first action sequence is refined by the second planning module when generating the second action sequence, f) the action sequence generated by the second planning module is used to generate and output control signals for controlling the production system.
