Abstract
Abstract A design assisting apparatus for assisting the design of parts of a product comprised of an assembly of a plurality of parts. The design assisting apparatus is comprised of a plurality of part suitability examination devices and a product suitability examination device. Each part suitability examination device is comprised of a part performance decision device, a part knowledge data base for each input, and a part optimization device. The part optimization device optimizes the initially input parameters of a part by referring to the part knowledge stored in the corresponding part knowledge data base. The product suitability examination device comprises a product performance decision device, a product knowledge data base, and a product optimization device. The product optimization device optimizes the parameters of the parts constituting the product by referring to the product knowledge stored in the product knowledge data base. The parameters of the plurality of parts output by the part suitability examination device are optimized to satisfy the target performances for the product and then are output. Also, a method for the same.
