In this paper, there is a research for providing environmental data to reflect environmental effects to the simulation for the aviation weapon systems by the construction of the synthetic battlefield. The results of the aviation engagement simulation are able to differ by environmental effect. This paper analyzes the real aviation battlefield and designs the synthetic battlefield based on the analysis. In order to construct the designed synthetic battlefield, we collects the real environmental data for the atmosphere and structures the collected data using GIS (Geographic information system interpolation). The main objective of this paper is to design the synthetic battlefield based on the derived environmental factors from the analysis of the real aviation battlefield, and it constructs the designed synthetic battlefield by the collection of real atmosphere data. The constructed synthetic battlefield provides the environmental data which are requested from the distributed simulation system, and it makes the system reflect environmental effects to the simulation.

This paper proposes a framework to construct the synthetic battlefield based aviation engagement simulation model for the distributed system. The proposed framework has the synthetic battlefield in the HLA (High Level Architecture)/RTI (Run-Time Infrastructure) based distributed system to reflect environmental effects into the aviation engagement simulation model. In an aviation engagement, the environment affects weapon systems such as detection and movement. Therefore, environmental effects are required to be reflected in the simulation. However, former researches are inadequate for complex operations of weapon systems that are requirements of the engagement simulation. Thus, the construction of the engagement simulation system of which reflects environmental effects based on environmental data is still difficult. The main objective of this paper is to propose a framework to solve the difficulty and constructs an example system based on the proposed framework.

Presented in the paper is a methodology for the distributed simulation of underwater warfare based on standard synthetic environment. In the case of underwater warfare simulation, it is very important to reflect environmental data, such as salinity and temperature. For the reusability and interoperability of environmental data, this paper adopts Synthetic Environmental Data Representation and Interchange Specification (SEDRIS(ISO standard for environmental data)). Although SEDRIS provides various merits as an international standard, applying of SEDRIS has been hindered by its broadness and heaviness. To relieve the difficulties, this paper proposes an efficient procedure to utilize SEDRIS technology for the atmosphere and underwater environment. This paper identifies SEDRIS structure for the atmosphere/underwater structured dimensional grid-based and implements the proposed procedure on the High Level Architecture (HLA) / Run-Time Infrastructure (RTI) to explain the generation of the battlefield in a distributed simulation system.

The US military is developing and improving SE-CORE and CVE to integrate war game between different kinds of systems, establish time-optimal CVE. Although South Korea is researching SEDRIS, etc. that is suitable for domestic circumstances, there are still many problems to be solved. The researchers suggest a way to semi-automate part of SNE process, by using the channel information of the image. This can help to improve speed of creating synthetic environment and facilitate information sharing to the others. If there is further research on the subject, it will be possible to develop automation technology to apply data from various information collection devices to synthetic battlefield environment (SBE).

Presented in this paper is a study for construction of a simulation system for the engagement of ground weapon systems. This paper proposes architecture for the simulation system based on agent simulation design methodology. Every entity of the proposed architecture is developed by assembling modularized agent components, and it enhances the reusability and composability of the entity. Consequently, time, costs, and efforts that are required to develop a new simulation system is able to be reduced by the enhancement. In the case of ground engagement simulation, it is very important to reflect environmental effects. Synthetic battlefield of the proposed architecture has environmental data of the battlefield and interacts with entities in the simulation system. The proposed architecture based simulation system can build swiftly various simulation models by the objectives and derive reasonable results from behaviors of entities that include environmental effects. This paper contains the construction of an example system based on the proposed architecture to verify the advantages of the architecture.

The real-time distributed simulation at the present age concentrates on the construction of a system development environment in order to accomplish a synthetic battlefield environment connected with Live-Virtual-Constructive simulation and to realize the Simulation Based Acquisition which supports the life cycle of weapon system. Accordingly this paper describes the development environment of the UML modeling and simulation which integrates the system analysis and design methods performed during the conceptual design phase of the reconnaissance UAV system development. An integrated framework linked with the UML simulation and X-plane visualization is suggested to efficiently perform the system analysis and design, and finally the implementation contents, the analysis of experiment results and concluding remarks are described.

The purpose of this study is to develop a systematic framework that can scientifically and quantitatively evaluate the effectiveness of an LVC training system. The proposed framework is based on QFD(Quality Function Development) methodology. The process of developing the framework begins with identifying various needs of stakeholders related to the introduction of the LVC training system. Then the effectiveness areas and factors are derived based on the needs. The measured effectiveness for each factors on alternatives by L, V, C systems are finally synthesized into the one overall effectiveness of each training system for relative comparison among them. In addition, we developed an Excel$^{TM}$-based tool based on the proposed framework methodology to provide an ease-of-use environment for rapid evaluation on the effectiveness of each training system with the given stakeholder need importance combinations, training scenarios and assets. The suggested framework and the measurement tool are expected to be useful for efficient knowledge-based decision making on an acquisition of the LVC training system.

During the past several years the ROK military has made an effort to build LVC synthetic battlefield that reflects the real world environment. In spite of its efforts, little has been accomplished. The disappointing achievement is mainly due to the lack of operational requirements and concepts, and policies or systematic approaches on the architecture and technology. Furthermore, there is insufficient understanding on the basic concepts and principles, and conflicting interests between organizations. In this study, I propose to construct an LVC based on the HLA that focuses on the system view and technical standard view, rather than the operational view. The proposed approach employs the information centric integration, focuses on an architecture convergence efforts based on the HLA/RTI, emphasizes the HLA compliance test and federation test, adapts to DSEEP, DMAO, and FEAT, and finally invents and implements an LVC Compliance Test System.
