Investigation on evaluation of design decision for door-shaped structure by using systematic knowledge analysis

Abstract

The paper employs the concept of relational knowledgebase and revised analytical hierarchy process (AHP) to carry out systematic analysis on evaluation of design decision for door-shaped structure. The knowledge audit proposed by the study includes structure kind, structure subsystem, technique function, boundary condition, limitation condition and applied engineering principle method. By means of the relativity of classified hierarchical knowledge, the study establishes relational engineering knowledgebase. The paper proposes calculating the ratios of occurrence numbers of related keywords from the relative patent and engineering knowledge documents on each hierarchy so as to determine the weighting value. Furthermore, combining with analytical hierarchy process, and taking the 3 techniques like local reinforcement and so on, as well as the 3 functions like lightweighting and so on for example, the paper finds the ratios of occurrence numbers of these technique functions and eigenvector, then carries out consistence inspection and importance evaluation. It effectively provides a priority order of design decision evaluation. © Springer-Verlag London Limited 2009.
