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.
