Automatic layout of PERT diagrams with X-PERT

Abstract

Techniques for visualizing PERT diagrams are presented. These techniques are used in the graphics tool X-PERT for computer-aided development and analysis of PERT diagrams, which provides an integrated environment to construct, display, and analyze PERT diagrams. Several graphics standards are supported, allowing for various styles of vertices (circles, boxes, etc.) and edges (straight lines, polygonal lines, horizontal and vertical segments, etc.).<>
