Abstract: During development of complex product systems,a large number of components and parts were outsourced to suppliers for designing and manufacturing.To develop complex product systems to satisfy customer needs,customer needs must be hierarchically derived into design process of system,components and parts respectively.A value-driven approach on requirements establishment was proposed for suppliers of complex product systems.Customer needs were modeled in terms of value with multi-attribute utility theory.The value model of customer needs was then hierarchically derived into value models of system technical requirements and component technical requirements respectively.Furthermore,to enhance suppliers' value perception,utility-based value models were transformed into currency-based value models based on even swaps.The approach was validated through an example that demonstrated the requirements establishment for engine supplier of commercial aircrafts.Value models of component technical requirements developed with the approach could be used by suppliers as objective function at conceptual design stage when definitive component requirements were not available,and they were useful for conducting design activities as early as possible.The approach could be extended into part level straightforwardly.
