document: A design to cost system for innovative product development Presents a prototype object-oriented and rule-based system for product cost modelling and design for automation at an early design stage . The developed system comprises a computer aided design -LRB- CAD -RRB- solid modelling system , a material selection module , a knowledge-based system -LRB- KBS -RRB- , a process optimization module , a design for assembly module , a cost estimation module and a user interface . Two manufacturing processes , namely machining and injection moulding processes , were considered in the developed system . The main function of the system , besides estimating the product cost , is to generate initial process planning , including the generation and selection of machining processes , their sequence and their machining parameters , and to recommend the most economical assembly technique for a product and provide design improvement suggestions based on a design feasibility technique . In addition , a feature-by-feature cost estimation report is generated using the proposed system to highlight the features of high manufacturing cost . Two case studies were used to validate the developed system
