Given the complexity of the emerging National Healthcare Information Network (NHIN) and Service Oriented Architectures (SOAs) due to multiple levels of system interactions, creating a valid and usable SoSE model for SOA application using a single technique that captures the desired level of details can be a daunting task. This paper details a hybrid approach to the modeling and simulation of a specific SOA that has been configured for potential defense applications, then adapted to healthcare. This system could also be used to allow connecting slow-speed remote telemedicine tools without violating the HIPAA Confidentiality, Security, and Availability requirements.
Modeling the proposed NHIN system design so the actual configuration will have the expected and desirable properties. This approach helps limit wasted programming or deployment resources by detecting and fixing robustness, security, flexibility, safety, or reliability faults early in the design and configuration process. Note, ironically, this model is an adaptation of a model originally configured for potential defense applications.
