Using Taguchi to optimise performance and product cost at the conceptual stage of design

The difficulty of obtaining a useful cost estimate at the design stage has long been acknowledged. Data for new products is hardly available and product specifications are often expressed as a range of values yet, only limited progress has been made to date to improve the quality of the average cost...
