This thesis puts forth a process for ontology driven distributed simulation through a case
study. Ontology is regarded as a domain model, including objects, attributes, methods and
object relations. The case study involves trajectory simulation. A trajectory simulation is a
piece of software that calculates the flight path and other parameters of a munition, such as
its orientation and angular rates, from launch to impact. Formal specification of trajectory
simulation domain is available as a domain model in the form of an ontology, called
Trajectory Simulation ONTology (TSONT). Ontology driven federation development
process proposed in this thesis is executed in three steps. The first step is to analyze the
TSONT and to create instances of individuals guided by the requirements of the targeted
simulation application, called Puma Trajectory Simulation. Puma is the simulation of a
ficticious air-to-ground guided bomb. The second step is to create the High Level
Architecture(HLA) Federation Object Model (FOM) using Puma Simulation individuals.
FOM will include the required object and interaction definitions to enable information
exchange among federation members, including the Puma federate and the Exercise
Manager federate. Transformation from the ontology to FOM is realized in two ways:
manually, and by using a tool called OWL2OMT. The third step is to implement the
Trajectory Simulation federation based on the constructed FOM. Thus, the applicability of
developing HLA federates and the federation under the guidance of ontology is
demonstrated.
