Abstract: A method for designing a turbomachine vane, in which predefined input parameters are transmitted to a neuronal network system and vane parameters are determined and output by the neuronal network system based on the transmitted input parameters. The neuronal network system has several separate neuronal networks each with an output layer, each of which determines one or more of the vane parameters and outputs same via the output layer. A first neuronal network and a second neuronal network belong to the separate neuronal networks of the neuronal network system and the vane parameter(s) which are determined by the first neuronal network and output via the output layer of said neuronal network differ(s) from the vane parameter(s) that are determined by the second neuronal network and are output via the output layer of said neuronal network.
