An Ontology Based Domain-Specific Composable Modeling Method for Complex Simulation Systems

Simulation modeling for complex systems should be both domain-specific to reflect domain characteristics of different subsystems and composable to integrate different domain models. Current research fails to provide a unified method to meet the two requirements simultaneously. In this work, an ontology-based domain-specific composable modeling method is proposed to solve this problem. This method employs layered ontologies including an upper ontology and a series of subdomain ontologies to formally represent the knowledge of the complex simulation system; and uses the ontology knowledge to design DSMLs for each subdomain. The case study on combat systems effectiveness simulation shows that domain models designed with different DSMLs can be technically and semantically composed since they have an explicit interaction framework and a common semantic foundation.
