Abstract
The methods of capturing and transferring the customer value in a product service system (PSS) are studied to capture the customers’ intrinsic value requirements, grasp the importance level of requirement, and transform it into design elements to more reasonably allocate resources and develop products more in line with the customers’ needs and more competitive at a minimum cost. First, a hierarchical model of the customer value based on the means-end chain theory is constructed to analyze the customer value from the perspective of customer expectations. In the process of determining the importance priority of value elements, the cloud model is used to process the expert evaluation information, and the competitive correction factor and the Kano factor are used to modify the basic importance of the value elements. The customer value in the PSS is then transferred to the product and service performance domain by constructing the parallel house of quality embedded cloud model (PHOQ-ECM). In other words, the cloud model is used to process the group decision-making values with fuzziness and randomness to complete the correlation calculation of the parallel HOQ. The important priority of the performance characteristics is then obtained. Finally, the abovementioned methods are applied to capture and transfer the customer value of a shearer, and the results are compared with other studies. The results show that the hierarchical model of the customer value can more deeply capture the customer value. The cloud model solves the problem of group decision-making with fuzziness and randomness. The competition correction factor and the Kano factor improve the accuracy of the importance priority of the value elements. PHOQ-ECM achieves the transfer and distribution of the customer value to two different objects of product and service and improves the accuracy of the performance characteristics importance priority. The method feasibility and validity are verified through the abovementioned analysis. Consequently, the method can effectively guide the PSS design.

Made in China 2025 pointed out the acceleration of the coordinated development of manufacturing and service and the promotion of the transformation of production-oriented manufacturing to service-oriented manufacturing [1]
This study proposed methods of capturing and transferring customer value in the product service system (PSS) to solve the problem of the traditional demand analysis method not capturing the intrinsic value demand of customers and deal with the fuzziness and randomness of group decision-making information and the distribution of the value elements to two different types of products and services
The value domain model based on the hierarchical theory of the customer value, which was constructed from the result and target layers of customer expectation, can more deeply capture the customer demand
Summary
Made in China 2025 pointed out the acceleration of the coordinated development of manufacturing and service and the promotion of the transformation of production-oriented manufacturing to service-oriented manufacturing [1]. The conceptual design of the PSS begins with the customer demand information, which is usually vague [3]. The methods of capturing and transferring the customer value in conceptual design must be studied. The present study captures the customer value from the perspective of customer expectation to help PSS designers obtain customer requirements in depth. The parallel structure HOQ is constructed to transfer and distribute the customer value to the performance domain to realize a reasonable allocation of resources and develop more competitive products with the lowest cost
