A Method for Mapping from Customer Requirements to Engineering Technical Characteristics

The paper analyzed the impact that the autocorrelation matrix on the weights of the engineering technical characteristics.Then the correlation matrix between the weights of customer requirements and the engineering technical characteristics was established, and the mathematical mapping model of the correlation matrix and the autocorrelation matrix was also established.A method for determine the weights of engineering technical characteristics was proposed based on the mathematical mapping model above.This method helps to the relative weights of engineering technical characteristics are determined, so that the results of configuration design are closer to the actual requirements of customers.Finally, the garbage crusher of an enterprise is taken as example, which validates the application of the method above.
