An Analysis on the Effect of PBL(Performance Based Logistics) Application for ROK Navy Landing Ship Fast(LSF-II)

Extent of damage analysis of naval ships subject to internal explosions

A well-balanced naval ship design to enhance the survivability from the initial design stage in parallel with other designs focusing on the major function and its inherent mission is considered as a desirable design trend in ROK navy since Cheonan sinking accident. Because it is difficult to estimate a hit location of a given threat for survivability evaluation, a statistical approach based on multiple-hit scenarios is frequently addressed, and it is necessary to accomplish rapid analyzes considering the tight design schedule. In addition, accurately estimating the extent of damage caused by the given threat is also an important matter to secure the reliability of evaluation. In particular, the empirical formula-based damage extent estimation method, which is frequently used for initial rapid vulnerability analysis, has limitations in not faithfully reflecting the latest technology advances such as hull design changes and diversification of threats, so researches on this have been continuously accomplished. In this study, a method for analyzing the extent of damage was developed considering the structural response of a ship to damage under a blast load. The proposed method quickly and easily calculates the extent of damage using physical design parameters together with the accurate analysis results and is also very effective at the initial design stage of the naval ship (e.g., in evaluating various design candidates for structural configurations). To show the effectiveness of suggested method, FLACS, a well-known commercial program for explosion analysis, is used for the analysis of nine representative scenarios together with the stepwise validations of the suggested procedure; the analysis results are observed the same in most cases with the developed program based on the proposed procedure, with a difference of approximately 15% for one scenario.

Purpose ROK Navy intends to secure the Korean-type aircraft carrier in order to effectively prepare for various future security threats. This study, the efficiency was evaluated through the relative comparison between the scale of aircraft carriers and operational capabilities(aircraft on board, cruising range), and optimization of operational capabilities of the Korean-type aircraft carrier that could be acquired was presented. Methods A DEA(Data Envelopment Analysis) model was applied to aircraft carriers(16 aircraft carriers in 10 countries) currently in operation and scheduled to be possessed in the world. As input variables, the full-load displacement, length, and width of aircraft carriers were selected. As output variables, the aircraft payload, cruising range were selected. Results The relative efficiency score of the Korean-type aircraft carrier currently being evaluated is 1.221, and it was evaluated as a small amount aircraft on board and short cruising range compared to the scale. Based on scale of the Korean-type aircraft carrier, the optimization of operational capabilities calculated by aggregating benchmark groups, are 19 aircraft on board and 11,597NM in cruising range. Conclusion Through this method, it will be possible to optimize of operational capabilities of the Korean-type aircraft based on efficiency.

고장확률 기반 계획정비 대기행렬 시뮬레이션: 해군 전투함정을 중심으로

The constant maintenance interval performed by ROK Navy ships has the advantage of convenient maintenance planning. In the past study, the failure rate of the ship continued to change with the life of the ship. Planned maintenance performed at regular intervals may not be appropriate to maintain the varying amount of failure of ships. Probability-based maintenance considers the changing amount of ship failure. Although the effect of probability-based maintenance was derived from previous studies, it was studied based on a single ship. Therefore, in this study, the effect of applying probability-based maintenance to multiple ships was confirmed as in reality. When maintenance was performed according to probability, the maintenance time overlapped and queuing occurred. The system dynamics simulation was performed considering the advantages of applying probability-based maintenance and the disadvantages due to queuing at the same time.

This paper aims to analyze various figures of military unit slogans of the ROK Navy. For this purpose, total of 136 unit slogans of battleships and ground units were selected for analysis. The 227 figures, which were applied to the selected units slogans, were divided into 2 figurative modes. The first was the figures of thought (53%) and the second was the figures of language (47%). The former then was classified as trope, figures of association, figures of citation, and the latter was classified as figures of structure and figures of rhyme. Among the figures of thought, for the trope, the metonymy was mostly used. For the figures of association it was the hyperbole, and for the figures of citation the allusion. And among the figures of language, for the structure, the ellipsis was mostly used and for the figures of rhyme the assonance. The most preferred figures among military unit slogans was the hyperbole, which was represented in 48 slogans, accounting for 35.3% of the total. This type of rhetorical devices demonstrates the combat power and the military spirit of the unit, and emphasizes their pride, while envisioning a victory in a battle.

This study aims to analyze various linguistic usage of the military unit slogans of the ROK Navy. For this purpose, we explain the structures and meanings of the military unit slogans. The result of the research is summarized as follows: First, the military unit slogans are defined as phrases that implicitly express the mission, characteristics, history, tradition, and core values of the unit. These also function as perlocutionary acts that persuade slogan receivers (soldiers) to change their thinking and behavior. Second, the most commonly used structures of military unit slogans are: the written letter of <Korean>, the structure of <expression+name of unit>, and the compositional pattern of ‘phrase pattern’. Third, looking at the meaning of military unit slogans, among the core values of the ROK Navy, ‘courage’ > ‘devotion’ > ‘honor’ are used in the order of frequency in military unit slogans, and expressions of superiority are the most common pattern of meaning delivery in military unit slogans. Based on these results, this study emphasizes the need for research on military unit slogans, and it also suggests a policy that can contribute to the expansion of research subjects and the systematic analysis thereof.

A Methodology for the Ship System Integration with Open Architecture : Focusing on the Total Ship Computing Environment based Architecture Building and Validation

In a series of recent launch tests, North Korea has been improving the firepower of its missiles that can target South Korea. North Korea’s missiles and submarines are capable of threatening targets in South Korea and are likely faster and more covert than the systems previously seen in North Korea. The advanced threats require that ROK Navy should not only detect them earlier than ever but also response quicker than ever. In addition to increasing threats, the number of young man that can be enlisted for military service has been dramatically decreasing. To deal with these difficulty, ROK navy has been making various efforts to acquire a SMART warship having enhanced defense capability with fewer human resources. For quick response time with fewer operators, ROK Navy should improve the efficiency of systems and control tower mounted on the ship by promoting the Ship System Integration. Total Ship Computing Environment (TSCE) is a method of providing single computing environment for all ship systems. Though several years have passed since the first proposal of TSCE, limited information has been provided and domestic research on the TSCE is still in its infancy. In this paper, we apply TSCE with open architecture (OA) to solve the problems that ROK Navy is facing in order to meet the requirements for the SMART ship. We first review the level of Ship System Integration of both domestic and foreign ships. Then, based on analyses of integration demands for SMART warship, we apply real time OA to design architecture for TSCE from functional view and physical view. Simulation result shows that the proposed architecture has faster response time than the response time of the existing architecture and satisfies its design requirements.

함정 성능개량을 통한 전력 발전 방안 연구 - 양만춘함 성능개량을 중심으로 -

ROK Navy had decided to conduct a combat system improvement as a new way of naval force development to meet future required operational capability, availability, reliability. Unlike pre-existing life cycle of battleship without considering the short life cycle of military technology, combat system improvement is inevitable for modern warfare. However, it needs more institutionalization because combat system improvement is conducted with a depot maintenance for more availability for the first time. I suggest eight development of battleship improvement. ① integrated process management between combat system improvement and depot maintenance, ② setting up standard operational procedure for improvement, ③ reflection of crew member's opinion at the design stage, ④ expanding the range of improvement, ⑤ exporting the know-how as a new business model, ⑥ outsourcing both improvement and depot maintenance, ⑦ building more work support facility, ⑧ requiring improvement in the first place. I hope that the suggestions contribute the institutionalization of improvement in the Navy.

손상통제 함상훈련 시나리오의 효율적 생성에 관한 연구

Damage control is a very important preliminary and primary activity to improve the survivability of naval ships by preventing spread of damage, and various types of onboard damage control training are conducted regularly on naval ships. The scenarios for these trainings should be well organized to improve the training efficiency. However, at present, it takes much time and effort to generate the training scenarios and there is a problem that the procedures and contents of the scenarios vary widely depending on the persons who generate, without the established methods and standards. In this paper, an efficient generation method of damage control onboard training scenarios has been established, especially for flood and fire on naval ships. Also a computer program has been developed based on the established method. The results showed that this method and computer program reduce the time and effort to generate these scenarios, and it is hoped that the method be used as a ROK Navy Standard.

우선순위 대기행렬 모형을 활용한 대형함정 정비용 건선거 운용수준 분석

Dry dock is an important facility for the maintenance of the hull of a ship. As the ship size of ROK Navy has become larger, the lack of large dry dock is getting worse. Therefore, it is necessary to improve the maintenance policy or construct an additional dry dock. Meanwhile, ROK Navy is using the dry dock for two types of maintenance: ordinary scheduled maintenance and prioritized urgent maintenance. This paper analyzes the operation level of large dry dock using the priority queuing model with two classes, which suggests insightful results for maintenance policy of ROK Navy as well as an analytic model of the operation level of the dry dock.

Study on Measures to Improve Fresh Food Sales at Military Commissaries (PX)

This study aims to confirm the appropriateness of fruit and vegetable sales at military commissaries, with the purpose of enhancing the physical health and morale of military personnel. In order to achieve this objective, we examined the actual conditions of fruit and vegetable sales at military commissaries and analyzed the soldiers’ awareness of fruit and vegetable sales through questionnaire surveys. The conclusions of this study are as follows: Firstly, fresh fruits and vegetables were not sold at military commissaries. Secondly, soldiers acknowledged the need for the consumption of fruits and vegetables and strongly expressed the desire for these fresh food products to be sold at military commissaries. Although the ROK Navy privatized military commissaries for the purposes of increasing management efficiency of national defense and strengthening combat power by transferring PX salesclerk soldiers to join combat personnel, this effort produced a negative effect of price increase. The following are proposals for improving this condition: fruit and vegetable products should be introduced to military commissaries through military welfare funds; fresh food markets should be established by closely cooperating with the local community’s agricultural producers; processed fruit and vegetable product (dry, frozen, airtight packaged, etc.) sales should be increased; and the privatization of the navy commissaries should be abolished.

대한민국 ‘해군표지’의 변천사

이 글은 한국의 해군을 상징하는 대표적인 문양인 ‘해군표지’가 변천되어 오늘날과 같은 문양으로 정착되는 과정을 들여다보고 그 역사적인 의미를 짚어본 것이다.BR 해군본부 차원에서 해군표지 제정의 필요성이 논의된 것은 1958년 7월경이었다. 해군을 총체적으로 상징하는 표지를 제정하기 위한 필요성이 제기되었고, 이에 따라 도안 모집이 예하 부대에 시달되었다. 9개 부대에서 총 12명이 응모작을 제출하였다. 응모작이 모아지자 해군본부 인사국에서는 1958년 9월 17일자로 예식복제위원회를 개최하여 4명의 후보작을 채택하였다. 그런 다음 1958년 12월 16일에 개최된 작전본부회의에서 당선작을 선정하고, 최종적으로 해군표지를 확정하였다. 고용걸의 당선작이 해군표지로 확정되었다. 고용걸의 도안은 닻과 날개가 달린 거북선, 체인, 대한민국해군이 쓰여진 리본을 소재로 하는 문양이었다. 이를 바탕으로 제작된 해군표지는 1959년부터 전 해군부대를 대상으로 사용되었다.BR 초창기에 제정된 해군표지는 1969년 8월로 접어들면서부터 변화가 발생하기 시작하였다. 그동안 사용해온 표지의 문양 중 거북선에 달린 날개형상이 외국의 것을 모방한듯하다는 점이 문제점으로 지목되었기 때문이었다. 이에 따라 해군본부는 해군표지를 새로운 문양으로 개정하는 작업을 추진하였다. 1969년 8월에 개최된 예식복제위원회에서는 당시 장교들이 사용하던 모표 문양을 근간으로 삼되 개정 이전 시기부터 사용해온 체인와 리본은 활용하는 방향으로 문양을 확정하였다. 장교 모표의 핵심 문양은 날개가 없는 거북선이었다.BR 개정된 해군표지는 대한민국 해군이 조선 수군의 전통을 계승한 군대이자 충무공 이순신의 후예임을 상징하는 문양을 반영한 것으로 해군 정체성의 특징을 독창적으로 표현하였다는 점에서 역사적으로 중요한 의미를 갖는다. 개정된 해군표지는 1970년부터 본격적으로 사용되면서 점차 정착 되어졌고, 이는 오늘날에까지도 변함 없이 계승되어지는 가운데 명실상부하게 대한민국 해군을 상징하는 대표적인 문양으로 그 위상을 자리매김하고 있다.

이지스함의 탄도미사일 방어를 위한 운용개념 도출

This paper describes the operational concept of the Aegis ship's missile defense. Recently, North Korea conducted a fourth nuclear-weapon test that involved the launch of a long-range missile and the underwater launch of an SLBM. The ground-based BMD (Ballistic Missile Defense) system is very limited for the SLBM of a miniaturized nuclear warhead; therefore, it is necessary to build a reliable sea-based missile-defense system. The ROK Navy has, however, only utilized the Aegis ship that is designed with a search-and-tracking sensor but is without a ballistic-missile interception capability. Given this information, this work focuses on the operational concept of the Aegis BMD by comparing the BMD capabilities of the ROK with those of the U.S.

샌드위치 패널을 이용한 함정탑재장비용 방진 베이스 개발

The underwater radiated noise can be reduced by decreasing the structure borne noise of the on-board equipment. Therefore, the structure borne noise of the onborad installed equipment is strongly restricted by ROK navy with MIL-Std 740-2. Usually, the vibration transmissibility from the equipment to the hull of the ship is dependent on its mount characteristics. Even though the double mount structure is proper to apply for ship board application rather than single mount, it is not widely applied due to the weight and volume resriction of the ship. Therefore, in this research, the base using sandwitch panel which can act as double mount structure is suggested and its noise reduction capacity is verified with analytic calculation as well as experiment.

A naval combat system is the system of systems who supports naval indigenous operations by integrating and inter-operating many different kind of weapons, which has characteristics of large scale complex computing system. ROK Navy has been built a blue ocean navy, so that large scale warships are under constructions. However, warship combat system architecture has not been well studied so far in Korea. The paper focuses on current combat system architecture and propose the next generation combat system architecture, which will give the development direction of ROK Navy. In order to complete combat system architecture studies, the system engineering process shall be applied to the study. Moreover, ARENA simulation tool is used for verification of combat system architecture. The system engineering process is as follows: next-generation naval combat system requirement analysis, functional architecture analysis and physical architecture analysis.

차세대 해상전투실험체계 구현을 위한 V-C 연동실험 및 연동분석 방법론 연구

The warfighting experimentation is the most important for the weapon acquisition process because the warfighting experimentation shall support the operation effectiveness as well as acquisition logicality. Therefore, ROK Navy is starting to set up the next generation warfighting experimentation systems. According to literature studies, there have been many studies regarding the interoperability of Simulators(Virtual) and Exercising models(Constructive), but not for studies regarding interoperability between Simulators(Virtual) and Analysis models(Constructive) that is the core component of next generation maritime warfighting experimentation systems. This study is dealing with the V-C(Analysis model) interoperability test and methodology of interoperation analysis. The purpose of the study is to provide the new analysis methodology through V-C(Analysis model) interoperation, which can be applied for the concept of operations(CONOPS) of next generation maritime warfighting experimentation systems. In addition to that, the study validates the suggested analysis methodology by the case study of a naval operation.
