Abstract: Service-oriented design is used in product development to accommodate diverse customer requirements and provide a profit-making strategy. Existing designs encounter difficulties in assessing design alternatives systematically during conceptual design involving customer heterogeneity and cognition vagueness. To evaluate these alternatives, a new systematic service-oriented design is proposed. The fuzzy analytic hierarchy process is used to handle the subjectivity and uncertainty of expert judgments and customer desires. In addition, the structure of service-oriented design within a mapping information flow is illustrated and then associated with technical characteristics via the results of the House of Quality. A consideration of influential design factors is developed to identify optimal alternative on the basis of the PageRank algorithm. Based on the integrated methods, a priority index is proposed to evaluate these alternatives, which can flexibly handle customer heterogeneity under limited technical conditions. At the same time, a design calculation program of a front axle suspension system was developed based on MATLAB GUI, which shows the design extensibility and robustness of the proposed approach. Overall, the results of the priority index-based method clearly demonstrate the superiority and appropriateness of the technique in selecting the optimal alternative. It also standardizes the design process from the case study of the front axle suspension system, provides rapid reasonable selection of the design scheme, and thereby improving intelligent design capacity from the perspective of product and its services.
