Methods for Visual Understanding of Hierarchical System Structures.

Summary: Pending
First printed as a 1979 research report by Fujitsu, Ltd, under the title "Effective Representations of Hierarchical Structures, Research Report No.8," this 1981 article by a team of Japanese researchers is an extension of the theory outlined in Warfield's 1977 paper "Crossing Theory and Hierarchy Mapping." "Abstract: Two kinds ofnew methods are developed to obtain effective representations of hierarchies automatically: theoretical and heuristic methods. The methods determine the positions of vertices in two steps. First the order of the vertices in each level is determined to reduce the number of crossings of edges. Then horizontal positions of the vertices are determined to improve further the readability of drawings. The theoretical methods are useful in recognizing the nature of the problem, and the heuristic methods make it possible to enlarge the size of hierarchies with which we can deal. Performance tests of the heuristic methods... This paper and also the 1979 report are both in the IASIS File.
