Abstract: To solve the value sub-optimization problem stemming from requirements-driven design,a novel approach to develop a value model was proposed from irregular customer needs statements.The relationships among customer statements were inferred by using means-ends analysis and part-whole analysis,and the real customer needs were identified.Attributes for measuring customer needs were identified and selected with a decision model.Multi-attribute utility theory was introduced to model value of customer needs.The approach was enhanced with the capability of transforming dimensionless value in the value model back to one special dimension of customer needs with physical meaning such as surplus value.Aiming at the information quality problem in constructing process of customers needs value model,the corresponding sensitivity analysis technology was proposed.The proposed approach was applied to a customer needs value model of large civil aircraft,and the modeling and simulation were realized.
