A New Evaluation Method for Product Service System Scheme Based on Analytic Network Process and Niche Theory

In reservation to enhance the enforceability of the product service system scheme and avoid the waste of time and resources caused by the improper design of the scheme, it is necessary to evaluate the scheme effectively before the implementation of the product service system scheme. Therefore, this study proposes a product service system scheme evaluation method based on the analytic network process and niche theory and evaluates the product service system scheme with customer value as the evaluation index. First, an analytic network process is used to calculate the relative importance of various customer value types and stages of the customer activity cycle. Second, niche theory is used to calculate the relative advantages of different product service system schemes in delivering all types of customer value. Then, based on customer value perception, the customer’s evaluation of the value delivered by different product service system schemes is obtained, and the schemes are ranked according to the amount of value delivered. Finally, the proposed method is verified by evaluating the CNC machine tool product service system scheme as an example and comparing it with other evaluation methods. The results demonstrate that the proposed method is more accurate and effective.
