A Case Study on the Value Models of Ocean Transportation Service

VASEM is a methodology to be aware of service values among participants and to analyze values' relationship to direct service system design. Value model is an important part in VASEM, and is foundation of value analysis. Ocean Transportation Service is a typical service system. Take it as a case, we verify the usability of value model in a certain field. We analyze the values in Ocean Transportation Service System with 4-layer value model, introduce the forms and specifications of each model, and present a whole view of the service by VPM, POVN and VDM. On the last layer - VAM, Value Model is combined with SMDA model by value annotation. And we show a segment of the service process to form primary methods for value annotation.
