The predominant delivery system of manufacturing knowledge in modern design is Computer-aided Design (CAD) software. Although executing design analyses through CAD software during detailed design is effective, it is inefficient and results in sunk engineering costs. In this research a novel, graph-based design environment is presented that delivers DFM and DFA advice in early design. The development of this framework required the reclassification of the historic DFM/DFA knowledge base to align it with a design’s concept, preliminary layout and definite layout maturity levels. Utilizing these levels of maturity, three graph-based early design environments were developed to represent designs and provide a framework for DFM/DFA assessment. Several artifacts were analyzed to validate the framework and early design cost estimating methods were explored. An Engineering cost analysis was successfully demonstrated on design concepts, and future work will develop Parametric and Engineering cost analyses for preliminary and definitive layouts to complement this research. The results of this research confirm that an early, graph-based design environment can provide manufacturing best practices and the quantification of design decisions to designers so they can balance the manufacturing implications of their design prior to investing time in CAD-based detailed design. 2014-10-27 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1397467818 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1397467818 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
