A service value co-creation process model for energy saving service business using inverters or transformers

This research proposes a new methodology of maximizing the co-created service value based on the service attribute vectors, which provides the process to evaluate and maximize the service value mathematically. The service value is evaluated by an inner product of service attribute vectors. It is applied to the service value co-creation process - KIKI model. In order to show the effectiveness of the proposed methodology, a case of energy saving service business using inverters as a product service system is investigated.
