Role of Product Life Cycle on Product Service System (PSS): Emerging Needs and Challenges

Product Service Systems (PSS) is a concept which means product and service are integrated to meet customer requirements. It has many applications in several industries. In current researches, Product Life Cycle Modelling and Service Engineering (SE) are main methodologies to design and model PSS. This paper proposes a framework of service life cycle integrating product life cycle. Each stage of service life cycle contains a number of service processes. Each service process is modelled using Service Engineering. This paper also proposes a primary input& output parameters system for the service process model, which integrates costs, resource consumptions and states of product or customer. At the end of the paper, the authors discuss the future work to improve this model.
