Abstract
In service design, reusability of knowledge about service case greatly affects success and failure of design and quality of design solution, and efficiency of design. We have already introduced the methodology which supports deriving candidates of function deployment using Universal Abduction Studio (UAS) in view model. In this report, we introduce the methodology which supports deriving a new agent in service design using UAS to increase reusability of knowledge about service case, and extend the knowledge representation scheme in function structure by including the information of parameter.
