Abstract

Reliability in the course of weapons system development and operation is a key measure of the ability of a system to perform the required functions under specified conditions over a specified period of time, and the mission confidence for the assessment of mission fulfillment is an important indicator of victory or defeat in a battle. Mission reliability indicates the probability that a given task will succeed or fail in an event or environmental situation over a given period of time. The existing mission reliability was calculated after creating a confidence blow map with only physical connections based on the mission. However, as modern weapons systems evolve and advance, the related equipment structure becomes increasingly complex, making it impossible to express mission relevance when mission classification is required based on functional or physical connections. In this study, the mission reliability was calculated for a gun control system, which is part of a ship's combat system, by expressing the association between the physical and functional structures using the design structure matrix technique and the interface matrix technique. We expect the study results to be used as verification data for mission reliability.

무기체계 개발 및 운용과정에서의 신뢰도는 시스템이나 구성요소가 지정된 기간 동안 지정된 조건에서 필요한 기능을 수행하는 능력의 핵심 척도이며 임무달성의 평가를 위한 임무신뢰도는 전투의 승패를 좌우하는 중요한 지표이다. 임무신뢰도는 특정 기간 동안 주어진 임무가 이벤트나 환경상황에서 성공과 실패할 확률을 나타내며, 신뢰도 산출시 장비의 동작여부만을 고려하는 것이 아니라 시스템의 임무를 물리적 및 기능적으로 구분하여 임무의 수행 신뢰도를 산출하게 된다. 기존의 임무신뢰도는 임무에 따른 물리적인 연결만을 가지고 신뢰도 블록선도를 작성한 후 신뢰도를 산출하였다. 하지만, 현대 무기체계들은 발전하여 고도화되면서 장비 구조가 복잡해져 기능적 또는 물리적 연결에 따른 임무 구분이 필요한 경우 임무 연관성 표현이 불가하다. 이에 본 연구에서는 설계구조행렬과 인터페이스 매트릭스 기법을 사용하여 물리적 구조와 기능적 구조의 연관성을 표현하여 함정 전투체계 시스템 중 한 부분인 함포통제 시스템에 대하여 임무신뢰도를 산출하였다. 본 연구결과를 바탕으로 임무신뢰도 검증자료로 활용되기를 기대한다.
