Scenario management practices in HLA based distributed simulation

2010-04-01
Training in a distributed simulation generally involves carefully designed and constructed simulation scenarios to fulfill the training aims. The simulation scenarios (i.e. federation scenario) play an important role in the federation design and development as specified in Federation Development and Execution Process. The simulation scenarios are used in every step in distributed simulation arena from the beginning (analysis and design) of a distributed simulation development to the execution. Such an extensive use of scenarios in a distributed simulation dictates a scenario management. In a distributed simulation, the scenario management includes the activities of scenario development, scenario loading, scenario distribution, event injection, and scenario-related data collection in a distributed training. This article explains the major concepts of simulation scenarios, introduces a scenario object model, and discusses the main activities in scenario management in a distributed simulation with a practical view. This article also presents a running real-life example of a naval distributed interactive simulation to illustrate the scenario management activities.

Federation architecture modeling: A case study with NSTMSS
Molla, Ayhan; Sarioǧlu, Kaan; Topçu, Okan; Adak, Mehmet; Oğuztüzün, Mehmet Halit S. (null; 2007-12-01)
We discuss the practical issues in modeling federation architectures in the case of Naval Surface Tactical Maneuvering Simulation System (NSTMSS), an HLA-based distributed interactive simulation system. We model the architecture of NSTMSS conforming to the Federation Architecture Metamodel (FAMM). FAMM provides a formalized language to specify the communication behaviors of federates along with their object models. Federate behavior specification is based on Live Sequence Charts. A federation architecture m...
Simulation of biped locomotion of humanoid robots in 3D space
Akalın, Gökcan; Özgören, Mustafa Kemal; Department of Mechanical Engineering (2010)
The main goal of this thesis is to simulate the response of a humanoid robot using a specified control algorithm which can achieve a sustainable biped locomotion with 4 basic locomotion phases. Basic parts for the body of the humanoid robot model are shaped according to the specified basic physical parameters and assumed kinematic model. The kinematic model, which does not change according to locomotion phases and consists of 27 segments including 14 virtual segments, provides a humanoid robot model with 26...
Schedulability analysis of real-time multi-frame co-simulations on multi-core platforms
Ahsan, Muhammad Uzair; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2020)
For real-time simulations, the fidelity of simulation does not depend only on the functional accuracy of simulation but also on its timeliness. It is helpful for developers if we can analyze and verify that a simulation will always meet its timing requirements while keeping an acceptable level of accuracy. Abstracting the simulated processes simply as software tasks allows us to transform the problem of verifying timeliness into a schedulability analysis problem where tasks are checked if they are schedulab...
Dynamic model integration and 3d graphical interface for a virtual ship
Çalargün, Canku Alp; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2008)
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 ...
Real-time hardware-in-the-loop simulation of electrical machine systems using FPGAs
Üşenme, Serdar; Dilan, R.A.; Dölen, Melik; Koku, Ahmet Buğra (2009-11-18)
This study focuses on the development an integrated software and hardware platform that is capable of performing real-time simulation of dynamic systems, including electrical machinery, for the purpose of hardware-in-the-loop simulation (HILS). The system to be controlled is first defined using a block diagram editor. The defined model is then compiled and downloaded onto an FPGA (¿Field Programmable Gate Array¿) based hardware platform, which is to interface with the controller under test and carry out the...
