The dematerialising concept has formed a new management model: the product service system (PSS). PSS means that enterprises have changed the management concept of 'product foremost and service second' to 'service-based product' in design products, and the products are the tools produced and innovated for service. Therefore, the physical logistical service replaces the virtual service. However, during the transformation, the product service system also needs to emphasise cost, customers' satisfaction and environmental protection. This study analysed different types of integrated maintenance service and used multi-attribute utility analysis to discuss the overall utility of maintenance service. The operation cost, CO 2 emission and service satisfaction indicators of different maintenance service models were used as decision variables to determine the optimal maintenance system. Finally, a case study is described to demonstrate this research.
