Abstract
Manufacturing enterprises are making more efforts in providing high value added services in addition to their traditional product business. An ontological knowledge-based product service system (PSS) is present in this paper which is used as a decision support tool and offers a means of supporting decision-making for maintenance, repair, overhaul (MRO) solution finding. An ontology-based knowledge representation is developed to represent, accumulate and collect knowledge and experience emerged during the MRO services, which realizes the knowledge originated from the service process and served service process. An ontology-based knowledge reasoning method is used to find the semantically similar generalized product service cases. The PSS configuration scheme set is obtained by optimizing and assessing the selected cases. The reference service solutions for the specific customer requirements will be created using the proposed PSS. An initial attemp has been made to demonstrate the role of PSS as a decision support tool for MRO services.
