Model-architecture oriented combat system effectiveness simulation

Combat system effectiveness simulation (CESS) is a special type of complex system simulation. Three non-functional requirements (NFRs), i.e. model composability, domain-specific modeling, and model evolvability are gaining higher priority from CESS users when evaluating different modeling methodologies for CESS. Traditional CESS modeling methodologies are either domain-neutral (lack of domain characteristics consideration and limited support for model composability) or domain-oriented (lack of openness and evolvability) and fall short of the three NFRs. Inspired by the concept of architecture in systems engineering and software engineering fields, we extend it into a concept of model architecture for complex simulation systems, and propose a model-architecture oriented modeling methodology in which model architecture plays a central role in achieving the three NFRs. Various model-driven engineering (MDE) approaches and technologies, including SMP, UML, DSM, and so forth, are applied where possible in representing the CESS model architecture and its components´ behaviors from physical and cognitive domain aspects.
