We present a value-driven approach capable of determining the global optimization objective of service composition to satisfy high-level value expectations. In traditional service composition methods, global and local QoS requirements and constraints are directly raised by customers, then a set of service components (web services) are selected to achieve the optimized QoS. Yet in practice, there is...
Service modeling is a critical step in describing customer requirements and designing service systems. The quality of service models determines the quality of service systems to a great extent. To analyze the service models in a way that would show deficiencies in delivering service values, we propose the idea of "value annotation" by which expected values are labeled on the functional elements...
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...
Marine logistics service is one of the fundamental production services supporting the import and export businesses of other industries. The current marine logistics service eco-system formed spontaneously, and during its development, various types of service providers were stepwise imported and complex business collaborations formed between them. Based on our investigation on marine logistics services...
