The combat system has a different purpose depending on its mission. All functions of combat system are important, but, the components that related main functions for the purpose, are important than other components. Also, the hit probability of component is proportional to area of the component. Therefore, when we analyze vulnerability of combat system, to consider the importance and hit probability of component. Thus to improve reliability of combat system, we apply the analyzed result to design combat system. In this paper, we develop a vulnerability analysis program based on criticality which calculated from importance and hit probability of components by related researches. To do this, we propose a methodology to apply criticality of components, and define classification rates for calculating criticality based on FMECA. Additionally, we propose a technique of vulnerability analysis using criticality of components, and apply the proposed technique to develop and test the vulnerability analysis program for automation of analysis.키워드 : 위험도, FMECA, 부품, 취약성 분석, 전차
Recently, the development of reliability analysis system for combat system is required, because, necessities of integrated reliability analysis research are emphasized. In this paper, we develop a system which analyzes vulnerabilities for tank(or armored vehicle) based on the fault tree analysis(FTA) technique. The FTA is representative technique of reliability analysis to find cause of fault and calculate probability of fault. To do this, we propose a method to apply FTA technique into domain of vulnerability analysis for tank. Also, we develop the vulnerability analysis system using the proposed method. The system analyzes hit probabilities of components of tank based on multiple shot-lines, and calculates kill probabilities. The analyzed and calculated data support vulnerability analysis of tank.
Survivability of combat system is changed by various facts in dynamic battle field. Existing survivability analysis programs for a combat system analyze statically survivability for combat system in spite of dynamic battle environment. To overcome this limitation, we propose an agent-based modeling and simulation method for dynamic survivability analysis of the combat system. To do this, we have adopted DEVS formalism, SES/MB framework and agent technology for modeling components of the combat system and crews. The proposed method has advantages of being able to analyze not only a static survivability of the combat system but also a dynamic survivability of combat system by applying responses of crews in battle field.

In this paper, we developed and tested a program for prediction flash fire in a combat system. Purposes of the program are flash fire prediction of combat system for analysis vulnerability and survivability, and visualization for fire-related information. To do this, we defined critical components of the combat system which has probabilities of flash fire occurrence, and proposed Flash Fire Probability Tree which is based on Fault Tree Analysis(FTA). The program visualizes positions of critical components in combat system, positions of penetrated components, selected Flash Fire Probability Tree, temperature profile, and tables for properties of matters. 키워드 전투 시스템, 순간 화재, 화재 예측, 생존성, 취약성 분석
