However, functions of new product tend to be highly changeable and complex, so it would be an important issue to evaluate an appropriate combination of functions with the concerns of decreasing the design time, reducing production cost, and meeting customers' requirements. This study proposes a systematic process in evaluating product functions by assessing the subjective criteria of decision makers’ preferences and adopting the objective measures of performance appraisal.
This modeling process first uses quality function deployment technique to deploy the customers' requirements to the function attributes of the product in determining the quality plan according to the relative importance of customers' requirements, the competitor's product, and the sale strategy respectively, and then applies the data envelopment analysis method to evaluate the functions of the product and rank them by their efficiencies. Finally, a suitable combination of functions for the new product development can be obtained with a limited total production time. In the case study, the selected functions result in shorter production time, and satisfy more customers’ requirements. In addition, the product with functions selected by the proposed approval is similar to the one selected by project manager in actual project. The proposed model can assist the decision maker who faces the choices of function combinations in evaluating the efficiency of the entire product with better systematic judgments.
