PROBLEM TO BE SOLVED: To set proper control in a control object with every image forming device, and independently obtain the best control condition by the individual image forming devices by changing only a value to correct it by using a former membership function as a reference value in changing a membership function to be used by an external input means. SOLUTION: A storage means ROM 8 to store a control program, an information storage means RAM 9 to store an operation quantity and operation data and an external input means 10 are respectively connected to a CPU 2. A membership function of plural stages is prepared for the ROM 8, and in the case of a membership function coincident with the contents of a changing command from an operation part 6 or the external input means 10, itself can change its membership function. In the RAM 9, when the membership function or participant data is changed by input from the external input means 10, its contents are stored, and the changed contents are used as basic data of fuzzy inference of the next time. |
