PROBLEM TO BE SOLVED: To provide a design parameter decision supporting device which calculates the combination of design parameters which satisfy the final characteristic as a target condition, evaluates a coincidence degree with respect to a restricting condition and presents the combination of the design parameters. SOLUTION: The device is provided with a coincidence degree function storage part for storing the basic form of a coincidence degree function and a coincidence degree updating part. The coincidence degree updating part calculates the coincidence degree with each restricting condition with respect to the combination of decided parameter change amounts when a target characteristics value speck<d> i (i=1 to n) is expressed by a formula (I) when the number of design parameters is m and the number of satisfactory characteristics is n (n<=m) concerning the parameter change amountΔpj (j=1 to m) from a design parameter to be a certain reference. The updating part also stores the coincidence degree with the combination of the parameter change amounts and performs re-arrangement in order from the highest coincidence degree among the newly obtained coincidence degrees.
