If preventing it utilizes possibility by a functional evaluation at a design stage, there should be a bigger effect. The discovery of the unexpected problem becomes early, too and is effective for measures. I introduce a parameter design this time.
The parameter design is a method securing the stability reasonably. A big effect is provided when it inflects at a stage of the basic design to decide the large frames of the design. At the stage when a trial product does not exist, it is the method that is possible by the inflection of simulation and the model experimental device.
