Abstract: A customer's request is more appropriately reflected in the design. A method of processing a request for designing a device receives a required specification for a device from a user input and output device, searches a case similar to the required specification in the old case specification information, outputs the case similar to the required specification found in the old case specification information to the user input and output device, and calculates a specification of a design result of the device according to the required specification for an unauthorized input for the similar case from the user input and output device, or transmits a request for designing the device according to the required specification to an external design system, and outputs the design result of the device calculated or received from the design system to the user input and output device.
