초록

본 논문에서는 가변 연속사격 시간을 고려한 근접 방어 시스템(Closed-In Weapon System, CIWS)의 최적 무장 할당 알고리듬에 대해 다룬다. 본 연구에서 근접 방어 시스템의 무장 할당 문제는 혼합정수계획법(Mixed Integer Linear Programming, MILP)을 기반으로 정식화된다. 제안한 방법은 연속사격 시간을 교전 사거리와 관계없이 일정하다고 가정한 기존 연구와 달리 사거리에 따른 요격확률을 바탕으로 가변 연속사격 시간을 고려한다. 따라서 기존의 방법대비 보다 현실적인 교전상황을 반영할 수 있을 뿐만 아니라 표적 대응시간을 향상할 수 있다. 본 논문에서는 가변연속사격 시간이 반영되도록 기존의 혼합정수계획법 기반 무장 할당 문제를 변형시켰으며, 상용최적화 프로그램을 활용한 수치 시뮬레이션을 통해 제안한 방법의 성능을 검증하였다.

This paper deals with an optimal Weapon-Target Assignment (WTA) algorithm for Closed-In Weapon Systems (CIWS), considering variable burst time. In this study, the WTA problem for CIWS is formulated based on Mixed Integer Linear Programming (MILP). Unlike the previous study assuming that the burst time is fixed regardless of the engagement range, the proposed method utilizes the variable burst time based on the kill probability according to the engagement range. Thus, the proposed method can reflect a more realistic engagement situation and reduce the reaction time of CIWS against targets, compared to the existing method. In this paper, we first reformulate the existing MILP-based WTA problem to accommodate the variable burst Time. The proposed method is then validated through numerical simulations with the help of a commercial optimization tool.
