In this paper, a "flow model" expressing the flow of service contents and service channels is newly introduced into service modeling which the authors have proposed. Here, service is regarded as a conversion operator of contents, and expression of the dynamic feature. Multiplex structure of service can be represented by a sequence of services. The "flow model" clarifies the difference between the whole structure and its partial structure called "scope" and "view", and specifies the relation between contents and channels. A basic simulation is programmed by STELLA according to this model in order to design services and to evaluate them.
