Abstract
We proposed a new design knowledge management approach called quantity dimension indexing. Although the proposed approach is effective, the design engineering knowledge in actual design activities is described by literal expression. In this paper, we propose automatic indexing method to introduce the proposed approach to actual design activities. For automatic indexing, we create a dictionary of relation between expression and quantity. The design engineering knowledge described by literal expression is automatically indexed by quantity according to the dictionary in order of inclusive relation among expressions of the dictionary. Morphological analysis result is also considered. By automatically indexing a fault tree example based on actual design activities in a company, the possible feasibility of automatic technique is indicated.
