개체단위 M&S의 교전 결과에 대한 정확도를 높이기 위해서는 신뢰성 있는 무기효과지수를 바탕으로 피해 정도가 모의되어야 한다. 무기효과지수는 특정 교전 환경에서 무기체계와 표적에 대한 명중확률(Ph)과 살상확률(Pk)을 지수화한 값으로, 주로 JMEM 데이터나 JMEM 방법론에 따라 생산된 데이터가 활용되고 있다. 그러나 JMEM 방법론은 표적 중심부를 기준으로 원형공산오차를 통과하는 파편이나 탄의 격자 통과량으로 살상확률을 계산하기 때문에 지형, 대기, 장애물 등의 추가적인 환경 요소를 고려하기 위해서는 전문가에 의한 보정이 요구된다. 따라서 본 논문에서는 다수의 교전 및 환경요소가 반영된 무기효과지수 생산을 위해 공학급 무기체계 모델을 활용하여 몬테카를로 시뮬레이션을 수행하고, 그 결과 데이터를 바탕으로 메타모델을 생성하였다. 명중확률과 살상확률 메타모델로 로지스틱 회귀모델과 가우시안 프로세스 회귀모델이 각각 생성되었으며, 예시 시나리오에 적용하여 모델 적합도를 관찰하였다. 본 연구에서 제시한 절차를 따르면 개체단위 M&S의 입력자료를 효율적으로 생산할 수 있을 것으로 기대한다.

Wargame is a simulated military operation with certain rules, specifications, and procedures, in which soldiers can virtually and indirectly experience the war. The ROK Navy operates the Cheonghae model, a training wargame model for helping commanders and staff master the procedures for conducting the war. It is important for commanders, staff and analysts to know whether a warship can perform its missions and how long it can last during a war. In existing model, the Cheonghae, the probability of kill of a warship is calculated simply considering the number of tonnage without any stochastic elements, and the warship's mission availability is also determined based on predetermined values. With this model, it is difficult to get a value of the probability of kill that makes sense. In this dissertation, the author has developed a probabilistic model in which the warship vulnerability data of ROK-JMEM can be used. A conceptual model and methodology that can evaluate the mission performance of personnel, equipment, and supplies has been proposed. This can be expanded to a comprehensive assessment of wartime warship loss rates by integrating damage rates for personnel, equipment, and supplies in wartime.

Accurately predicting wartime resources requirements and preparing war supplies in peacetime is an important task that can determine the outcome of the war by guaranteeing the duration of the operation. The wartime warship damage rate is a measure of estimating the battle damage of our warships in the process of performing battles to achieve the war goal. In the previously studied wartime warship damage rate estimation method, when damage occurs, long-term repair is required due to the complexity and specificity of the ship structure. Only the case of a complete defeat at the level of sinking was defined as a damage, and even if it was impossible to perform a maritime operation mission, it was not estimated as a damage if the level of sinking was not reached. Therefore, in order to improve the reliability of the wartime warship damage rate, the equipment damage assessment level can be estimated based on the warhead weight of the threat weapon system, the vulnerability rate of the warship's equipment, and the warship's hull. In the future, it is expected that the estimation methodology proposed in this study will be used as a simulation logic when developing a model for analyzing the wartime resources requirements for the warship's equipment and hull.
