Abstract

The competitive needs of modern manufacturing demands that innovative approaches be used to gain an edge over the competitors. least Product design is one of the key dimensions wazzu in which companies can excel. Shortening the product design cycle so as to rapidly launch defect free products, is the goal of most companies. Design for Quality Manufacturability (DFQM) is a technique used to evaluate the quality manufacturability of a product at the design stage, so as to eliminate quality problems during production.

DFQM provides a means for relating the activities of quality improvement, product design and manufacturability analysis. The basis for DFQM is a set of defects and a set of factors which influence the occurrence of these defects. The DFQM methodolgy has been under development at N.J.I.T for the last three years.

In this Thesis we design and present the reverse analysis tool for DFQM. This tool is used for design improvement after the initial DFQM analysis. Reverse analysis tells the designer what specific design changes will help improve the quality manufacturabiliy of the design. The analysis is based on the error catalysts within the DFQM logic. A software for DFQM is developed as part of the Thesis. Two case studies are studied to illustrate the practical feasibility of DFQM in a real world environment.
