Abstract
In Service Engineering, a basic structure of a service that satisfies customer requirements is designed through phases of "development of functional structures" and "embodiment of functions." In the phase of embodiment, it is important, for the purpose of enhancing the quality of a design solution, to acquire a lot of knowledge in other cases. In Service Engineering, service functions are represented by "verb-noun approach" which may leads a different expression of the same functions, and this makes exploring entities that realize a function difficult. In this paper, to classify service functions with a unified representation, the "input-output approach" of functional modeling is introduced. The result of the verification shows that the proposed method is useful to unify service function representation and effective to manage service design knowledge in the embodiment phase.
