Abstract
Abstract This paper presents the design and development of an automated system to assist with Design for Assembly (DFA) analysis. The system is designed to accept information on alternative assemblies using DFA metaphors. Statistics are calculated for these assemblies so as to evaluate their assemblability. The alternative assemblies and improvements in any assembly design are evaluated using these statistics. A binary tree data structure is used in the DFA system to represent the design data. This structure is implemented by a linked method with three links in each tree node. This allows any arbitrary tree to be represented efficiently, and it also allows for unpredictable tree growth and easy tree manipulation. The user interface of the DFA system is managed by the “User Interface Management System”, that achieves direct and fast control of the screen by directly accessing the video memory.
