A rough set based approach to knowledge acquisition for product service system configuration

Product service system is a bundle of products and services. For higher customer satisfaction, product service systems have to be configurated to lead to desired customer perceptions. And it is necessary for configuration to discover the mapping relationship which is normally characterized by imprecision, uncertainty and non-linearity, from product service systems to customer perceptions. This paper proposes an approach based on dominance relation rough set to extract configuration knowledge considering customer perceptions. Loadometer product service system is used as a case to validate the proposed approach, and the results gain from the case show that the approach is effective.
