This study focuses on the operating requirements of multi-resolution modeling(MRM) in training war-game model and proposes solutions for major issues of multi-resolution interoperation between Combat21 model and tank multi-purpose simulator(TMPS). We study the operating requirements of MRM through interviews with defense M&S experts and literature surveys and report the various issues that could occur with low-resolution model Combat21 and high-resolution model TMPS linked, for example, when to switch objects, what information to exchange, what format to switch to, and how to match data resolutions. This study also addresses the purpose and concept of training using multi-resolution interoperation, role of each model included in multi-resolution interoperation, and issue of matching damage assessments when interoperated between models with different resolutions. This study will provide the common goals and directions of MRM research to MRM researchers, defense modeling & simulation organizations and practitioners.

Korea DM&S(Defence Modeling & Simulation) development plan includes construction of a distributed simulation model which enables us to construct, operate, integrate and connect war game simulations. US DoD and IEEE set the HLA/RTI as the standard of distributed simulation model. HLA/RTI models each simulator as a Federate and group of them as a Federation. Simulation with the model shows interoperability and finally executes a war game simulation. Because of different resolutions and features, it is not satisfied 'interoperability' and 'reusability' of simulation perfectly MRM (Multi Resolution Modeling) has been introduced, and many developed countries including the United States have studied the technology to simulate the model with different resolutions. This thesis proposes the need for introduction of MRM and analyzes both technical and operational validity when we apply MRM model to army war game simulations. For these purposes, we 1) find MRM main issues with the study about MRM basic concepts and case studies of MRM's applications, 2) present the need of MRM and its relation with DM&S development plan, and 3) analyze its technical and operational validity when we apply MRM to an example, CHANG-JO21 and JEON-TOO21.

Multi-resolution modeling(MRM) is required when simulating objects in variable resolution and can be applied for interoperating systems, which simulate objects in fixed resolution. However, most interoperation middleware do not support MRM, so participating models must handle several issues to simulate MRM system. In this paper, we propose an interoperation system, which is composed of several different resolution models, based on the High Level Architecture and Run-Time Infrastructure(HLA/RTI). In the proposed architecture, each model participates to a HLA federation through MRM adapter application, which supports data resolution conversion and HLA services while communicating with the model. MRM adapter application can be implemented based on an MRM adapter, and an adapter application development tool is proposed to support developing the application. Using the tool, developers can easily implement data resolution conversion component plugged-in HLA adapter. A case study is implemented in the proposed MRM system, and shows that models of different resolution works successfully with dynamic resolution changes.
