Patent ID: 7689523

Claim:
A design support method for extracting solutions for solving a failure or problem phenomenon when the failure or problem phenomenon occurs in a new case example of designing, comprising: a storing step of storing assembling operation/attribute coefficients as a database in advance, the assembling operation/attribute coefficients indicating potentials for failure in assembling of assembling operations and attributes respectively, the assembling operation/attribute coefficients being decided based on a large number of past case examples of designing where there occurred failure or problem phenomena; a computing step of calculating failure influence indices based on the assembling operation/attribute coefficients read from the database when there occurs a failure or problem phenomenon in a new case example of designing, the failure influence indices indicating influences of parts, assembling operations of each part, and attributes involved in each assembling operation on a failure in assembling; and an extraction/presentation step of displaying and presenting the failure influence indices on a screen so that ones of the parts, the assembling operations and the attributes can be extracted based on the failure influence indices, the failure influence indices having been calculated for the parts, the assembling operations and the attributes respectively in the new case example of designing.
