Towards the derivation of an integrated design and manufacturing methodology

Abstract

Design methods support the derivation of alternative design solutions, and based on product requirements, it provides a platform for the evaluation and selection of appropriate solutions. Because of the driving needs of design and manufacturing industries and also the quest to remain competitive, several design methodologies aimed at addressing aspects of industrial requirements have emerged. This study identifies current best practice design methodologies and their performance when compared with current trends in design and manufacturing. Based on the review, the strengths and weaknesses of current methods are highlighted and used as the platform to support the recommendation for an integrated design and manufacturing methodology. The integrated design and manufacturing methodology rest on the strengths of product design, cost engineering, enterprise and process simulation modelling techniques. This method can help in the (re)design and (re)engineering of products and processes for better cost indications; help determine appropriate manufacturing paradigms; perform virtual experiments to understand implication of production volume changes on designs and flexibility needs in production systems.
