This thesis addresses the improvement of a physically based modeling simulator Naval Surface Tactical Maneuvering Simulation System (NSTMSS), that combines different simulators in a distributed environment by the help of High Level Architecture (HLA), to be used in naval tactical training systems. The objective is to upgrade a computer simulation program in which physical models are improved in order to achieve a more realistic movement of a ship in a virtual environment. The simulator will also be able to model the ocean waves and ship wakes for a more realistic view. The new naval model includes a 4 degrees of freedom (DOF) maneuvering model, and a wave model. The numerical results from real life are used for modeling purposes to increase the realism level of the simulator. Since the product at the end of the thesis work is needed to be a running computer code that can be integrated into the NSTMSS system, the code implementation and algorithm details are also covered. The comparisons between the wave models and physical models are evaluated for a better real time performance. The result of this thesis shows that the integration of a 4-DOF realistic ship model to the system improved the capability of NSTMSS to give more data to the student officers while making maneuvers. The result also indicates that the use of waves and ship wakes had taken the simulator to a next level in the environment perception.

Goal oriented modeling of situation awareness in a command and control system
Soğancı, Hasan Ali; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2010)
This thesis presents a preliminary goal oriented modeling of situation awareness in a command and control system. Tropos, an agent oriented software development methodology, has been used for modeling. Use of Tropos allows us to represent, at the knowledge level, the Command and Control actors along with their goals and interdependencies. Through refinement we aim to derive an architectural design for the Situation Awareness component of an Air Defense Command and Control system. This work suggests that goa...
Coordinate systems for a naval virtual environment
Kılıç, Aslı; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2005)
The purpose of this thesis is implementing World Geodetic System (WGS) for Naval Surface Tactical Maneuvering Simulation System (NSTMSS), a High Level Architecture (HLA) based naval simulation, and also implementing body coordinate system for the ships of NSTMSS and its combination with WGS so that NSTMSS can be more accurate, and new ship dynamics models can be integrated to the NSTMSS environment more easily. To improve the coordinate system of NSTMSS these methods were used; World Geodetic System - 1984 ...
A bdi-based multiagent simulation framework
Yükselen, Murat; Polat, Faruk; Department of Computer Engineering (2008)
Modeling and simulation of military operations are becoming popular with the widespread application of artificial intelligence methods. As the decision makers would like to analyze the results of the simulations in greater details, entity-level simulation of physical world and activities of actors (soldiers, tanks, etc) is unavoidable. In this thesis, a multiagent framework for simulating task driven autonomous activities of actors or group of actors is proposed. The framework is based on BDI-architecture w...
HLA fom development with model transformations
Dinç, Ali Cem; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2010)
There has been a recent interest in the model-based development approach in the modeling and simulation community. The Model-Driven Architecture (MDA) of OMG envisions a fully model-based development process where models are created for capturing not only requirements, but also designs and implementations. Domain-specific metamodels and model transformations constitute the cornerstones of this approach. We have developed transformations from the data part of Field Artillery (FA) domain models to High Level ...
Formation preserving navigation of agent teams in 3-d terrains
Bayrak, Ali Galip; Polat, Faruk; Department of Computer Engineering (2008)
Navigation of a group of autonomous agents that are needed to maintain a formation is a challenging task which has not been studied much in especially 3-D terrains. This thesis presents a novel approach to collision free path finding of multiple agents preserving a predefined formation in a 3-D terrain. The proposed method could be used in many areas like navigation of semi-automated forces (SAF) at unit level in military simulations and non player characters (NPC) in computer games. The proposed path findi...
