More and more researchers, institutes and programmes have paid attention to product-service ystems (PSSes) in the last decade because PSS integrates tangible artefact and intangible service to achieve sustainability, improve enterprise competitiveness, and meet customer needs better. In order to respond to the industrial trend towards PSS and frame the related research, the state-of-the-art of PSS research and development are reported. Furthermore, in order to integrate fragmental PSS solutions, this paper proposes a framework for product-service lifecycle management (PSLM) and technologies of PSS development.
So, four categories are focused on: review of PSS, esearch about PSS development, a framework for PSLM, and technologies for PSLM (modular product-service development and ontology-based productservice knowledge expression and reuse). The preliminary solution of the implementation roadmap and technologies for PSLM which need to be perfected is proposed to lay a basis for further development and application of PSS for the benefit of industries. Keywords: product-service systems (Psses); product-service lifecycle management; PSS development; modular product-service development 1.
Introduction Since the early 1990s, the driver in our economy has been changing from production f material goods to product-service offers based on knowledge and information (Roy and Baxter 2009). The service proportion of output and profits in manufacturing enterprises are increasing. It has become an important trend in the manufacturing industry that service is used to enhance the competitiveness of businesses as well as an important source of values (Sheehan 2000, Mont 2003).
There are mainly two manifestations, the first is manufacturing companies are more and more focused on the service in the design or development phase; the second is manufacturers xpanding their activities to the entire lifecycle of the physical products. As a response to this trend, more and more enterprises are beginning to take this service-oriented model of manufacturing, and there are already a lot of successful examples. Rolls Royce offers ‘Total Care Package’ and ‘Power by the Hour’ rather than transterring ownership ot the gas turbine engine.
