SYSTEMATIZATION OF DESIGN PROBLEMS BY GRAPH THEORY
A graph-theory-based systematization method of design problems has been proposed aiming at carrying over obtained engineering knowledge in constructions of large-scale systems. This method focuses on deriving decision making sequence in assigning values on specifications, rather than pursuing accuracy in each evaluation. A prototype software has been verified by comparing the derived decision making sequences from a set of equations among major specification parameters of a nuclear plant to an empirically built algorithm by experts. This method has a potential in handling non-quantitative specifications by automatically switching inter-dependency structure among the relevant quantitative specifications.
