Comprehensive Use Case Scenario Generation: An Approach for Modeling System of Systems Behaviors
Whitcomb, Clifford A.

This paper describes a reusable approach using automatic use case scenario generation to specify system of systems (SoS) behaviors. The approach leverages the Monterey Phoenix (MP) language and tools, which extend current methods significantly by making a larger number of SoS use case scenario variants available to SoS analysts. Having described how MP structures behavior models to accomplish this task in previous papers, this paper provides model-building details and advice that takes readers through the approach so they may repeat it on a SoS of their own interest. A simplified SoS model of three systems interacting in a humanitarian assistance and disaster relief (HADR) scenario is used to demonstrate the approach. The HADR example highlights the model structure features that enable automatic SoS use case scenario generation, and supporting descriptions of each part of the model are provided. The paper concludes with a summary and brief discussion of ongoing research areas that support bringing this approach into the mainstream of system of systems engineering practice.
