Abstract
Assembly is one of the most important stages of product development. Design for
Assembly (DF A) is one of the approaches to improve the product designs for easier and
less assembly cost with high functionality of the products. The main objective of the
research work is to develop an improved DF A system. The developed system is aimed at
supporting new techniques for DF A and to provide users opportunity to assess and reduce
the total assembly time and cost of the product and improve the product value at the early
stage of the design process. The system is also expected to assist the designer in product
redesign based on the general DF A rules and principles. In order to achieve this task,
Lucas DF A and Value Engineering are reviewed in the current research work towards
developing a framework for DF A analysis. The scope of the work includes systematizing
the assemblability analysis for a product through generic sequence of design activities
with rational basis. The inherent knowledge of the DF A rules and principles are used in a
systematic way throughout the assemblability analysis. The prototype software has been
developed in this research work for the convenience of the designers. The software could
facilitate quick result with best accuracy to be obtained and to preserve the design data
for future reference. Two case studies have been performed using the software to
illustrate the proposed method with a view to determine its effectiveness in actual
application. The case studies results show that the developed evaluation system is able to
improve the value and reduced the assembly cost of the redesign product.
