        A Study on the Measuring of Combat Effectiveness for Naval Frigates Using Analytic Hierarchy Process

        김기태(Kitae Kim),임요준(Yojoon Lim) 한국산업경영시스템학회 2021 한국산업경영시스템학회지 Vol.44 No.1

        Modern combat has been extended to the concept of real-time response to a variety of threats simultaneously occurring in vast areas. In order to quick command determination and accurate engagement in these threats, the combat system has emerged in frigate. Frigates conduct anti-surface, anti-submarine, and anti-aircraft as the core forces of the fleet. In this study, the combat effectiveness measures naval frigates using AHP (analytic hierarchy process) method. A hierarchical structure for measuring the combat effectiveness was developed, and weights of criteria were calculated by expert surveys and pair-wise comparisons. In addition, the combat effectiveness of frigates was synthesized and compared. The weights for each attribute were calculated, and the weights for the three main attributes were in the order of act (0.594), evaluate (0.277), and see (0.129). As a result of calculating the weight, anti surface warfare (0.203) was the highest. The combat effectiveness of FFG Batch-III, which has advanced hardware and software and improved combat system capabilities, see (1.73 to 2.56 times), evaluate (1.68 to 2.08 times), and act (1.31 to 3.80 times) better than the comparative frigate. In summarizing the combat effects of the frigate, FFG Batch-III was 1.41~2.95 times superior to the comparative frigate. In particular, a group of experts evaluated the act importantly, resulting in better combat effectiveness.

        ISAR 영상 기반 해상표적 식별을 위한 인공지능 연구

        김기태(Kitae Kim),임요준(Yojoon Lim) 한국산업경영시스템학회 2022 한국산업경영시스템학회지 Vol.45 No.2

        Artificial intelligence is driving the Fourth Industrial Revolution and is in the spotlight as a general-purpose technology. As the data collection from the battlefield increases rapidly, the need to us artificial intelligence is increasing in the military, but it is still in its early stages. In order to identify maritime targets, Republic of Korea navy acquires images by ISAR(Inverse Synthetic Aperture Radar) of maritime patrol aircraft, and humans make out them. The radar image is displayed by synthesizing signals reflected from the target after radiating radar waves. In addition, day/night and all-weather observations are possible. In this study, an artificial intelligence is used to identify maritime targets based on radar images. Data of radar images of 24 maritime targets in Republic of Korea and North Korea acquired by ISAR were pre-processed, and an artificial intelligence algo- rithm(ResNet-50) was applied. The accuracy of maritime targets identification showed about 99%. Out of the 81 warship types, 75 types took less than 5 seconds, and 6 types took 15 to 163 seconds.

        승선근무자의 병역법 논란과 비상대비자원법에 따른 역할수행 방안

        이영수(Youngsoo Lee),임요준(Yojoon Lim),이윤철(Yuncheol Lee) 한국법학회 2018 법학연구 Vol.72 No.-

        최근 국방개혁에 따른 병력감축과 대법원의 양심적 병역 거부 무죄 판결에 이어 병역법의 한 수단인 대체복무제가 국민적 관심으로 논쟁이 뜨겁다. 이와 관련된 여러 의견수렴에 있어서 반드시 지켜야 할 기준은 공정성과 형평성이다. 그 중 형평성은 대체복무제도의 성패를 가늠하는 중요한 열쇠이며, 무엇보다 현재 군 복무 중인 젊은이들의 사기(士氣) 저하가 국방력 약화로 이어질 수 있기 때문이다. 또한 국가비상사태 및 재난시 국가생존의 지속능력을 유지시키는 조선해운분야의 선박과 전문인력 등에 있어서 경영난의 침체와 저임금 외국노동자에 의해 시장의 점식되고 있다. 이에 병역법 상 승선근무예비역 제도의 관리상의 문제점이 심각한 수준으로 치닫고 있으며, 복지와 인권의 사각지대로 자리잡아 제도상의 보안이 요구되고 있는 실정이다. 따라서 병역법에 대한 재진단과 향후 비상대비자원법 등이 국가안보와 해양력에 미치는 영향을 고찰해 보고 ‘승선근무예비역’의 형평성을 군사적 역할의 정당성으로 제시하고자 한다. This paper concerns the militarization of Merchant Marine Reserve for the naval force. The mobilization of merchant seamen in the history from Korean War to Iraq War exemplified the importance of merchant marines in sealift, and militarizing merchant marines and supporting mobilized merchant vessels have been pivotal for the victories in war. In times of war, Merchant Marine Reserve is thus expected to conduct roles as an irregular military component in modern warfare, and furthermore to serve as the fourth military force to assume strategical, operational, and tactical roles. This paper aims to present these strategical, operational, and tactical roles of merchant marines as military force and navy reserve force.
