Abstract
In a system according to the present invention, when there occurs a failure or problem phenomenon in a new case example of designing, assembling components (parts, assembling operations and attributes thereof) are input. Failure influence indices are calculated for the assembling components respectively based on assembling operation/attribute coefficients. Assembling components to be improved are extracted, and specific solutions built for the assembling components respectively are displayed on a display so that a specific solution can be selected therefrom. Specific risks expected for the selected solutions respectively are built. The specific solutions and the specific risks are displayed on the display so as to be associated with each other.
