  • "선용품"이라는 용어는 선박에서 사용되는 모든 관련 기계적 부속품(SPARE)와 소모성 자재(STORE)를 통칭하여 부르는 용어이다. 자동차나 다른 기계류와 달리,선박은 원양을 운항하기에 긴급하거나 급박한 상황의 발생으로 기부속에 대한 수요가 발생할 경우 긴밀하게 대응하기가 어려운 환경에 놓여져 있다. 본 연구에서 연구자는 공급지 결정을 가능하게 하기 위해, 실제 보급사례들을 바탕으로 데이터를 분석하고, 각 선주사 및 선박관리업체 측을 대상으로 설문조사를 실시하여, 그 결과를 분석해 선박의 선용품 보급지 결정방안을 일반화 하고자 한다 .

  • The term "articles for ship" is a general term for all relevant mechanical accessories (SPARE) and consumable materials (STORE) commonly used in ships. Ships commonly are at sea, so it is difficult to respond rapidly to the demand for them in an emergency situation. In particular, it is more difficult to determine the boarding location of tramper ships as it is more difficult to predict the next sailing route in advance. The purpose of this study was to identify the important factors to be considered in determining the boarding location of tramper ships through a survey of each ship owner and ship management company. This valuable information on the proposed supply procedures for each country and port, would be an efficient way to supply articles for ships.

  • The recent conflict between Russia and Ukraine underscores the significant of military logistics support in modern warfare. Military logistics support is intricate and specialized, and traditionally centered on the mission-level operational analysis and functional models. Nevertheless, there is currently increasing demand for military logistics support even at the engagement level, especially for resupply using unmanned transport assets. In response to the demand, this study proposes a task model of the military logistics support for engagement-level analysis that relies on the logic of ammunition resupply below the battalion level. The model employs a decisions tree to establish the priority of resupply based on variables such as the enemy's level of threat and the remaining ammunition of the supported unit. The model's feasibility is demonstrated through a combat simulation using OneSAF.

  • Recently, there has been an increasing need to expand the supply of renewable energy as a solution to greenhouse gas emissions. Therefore, as a measure to promote domestic renewable energy investment and gradual expansion, this study analyzed the investment value of renewable energy projects utilizing the unoccupied spaces of public enterprise's facilities and presented a strategic decision-making framework to support efficient national land development and government measures. The NPV was estimated to be 286 million won if the expansion of the facility was not considered, but it is reasonable to postpone the expansion decision because the value of -130 million won was calculated if the expansion was considered. On the other hand, the real-option value was estimated to be 444 million won, taking SMP uncertainty, expansion, and abandonment options into account, and an additional value of 288 million won was calculated from an analysis of the expansion project using the existing NPV analysis.

  • 인터넷의 보급에 의해, 전자화된 문서가 대량으로 유통되게 되었다. 이에 따라, 대량의 전자화 문서로부터 검색 요구에 해당하는 문서를 검색한 기술이 요구되고 있다. 문서 검색 시 복수의 화제나 분야가 혼재한 문서로는, 검색 요구에 해당하는 내용이 문서의 일부분에 존재하는 경우가 대부분이다. 이처럼 문서전체를 검색 대상으로 하는 것이 아니라 검색 요구에 일치한 일부만을 검색한 패시지 기술이 주목되고 있다. 본 논문에서는 패시지가 있는 분야의 화제에 관하여 쓰여진 정리로서 파악하고 부야 연상어를 이용하고, 패시지를 결정한 방법을 제안하였다. 결정된 패시지와 미리 사람에 의하고 결정한 패시지가 어느 정도 일치하고 있는지를 비교하여 제안 방법의 유효성을 평가한 결과 적합율이 약 80%, 평균 재현율이 약 67%되어, 유효성을 확인할 수 있었다.

  • This study was conducted to investigate policy priority with respect to development of a smart farming system. Professors, researchers and policy makers in related fields were surveyed to develop a long-term plan and improved direction for the smart farming system, and the AHP (Analytic Hierarchy Process) was used for analysis. Overall, 61 experts in the frontiers of the field were surveyed and 42 questionnaires were analyzed. The results showed that the most important factors influencing development plans are increasing the income of farmers, minimizing management costs and standardizing and localizing smart farming systems. However, some plans differ with respect to economic and technology factors; therefore, those things should be analyzed in more detail by experts.

  • In order for a machine, especially used in the defense industry, to consistently operate during its life-time, lots of study has been done in machine design as well as machine maintenance. However, the realistic study is necessary in management and operation of a military support facility, where spare parts are stored and retrieved. In this paper, efficient arrangement of spare parts are proposed to acquire increased in efficiency and decreased in cost for operation management of the military support facility. First, spare parts is assorted by MTBF(Mean Time Between Failure) and divided in to three groups A/B/C as an alternative arrangement. Each defined alternatives will go under simulations and RULA(Rapid Upper Limb Assessment), which is posture classification scheme evaluation attributes, to find working time and posture difficulty and lastly by entropy measurement to be selected. This research proposes the efficient spare parts arrangement in military support facility to minimize working time and posture difficulty. By taking system and human engineering approach together into consideration, it will lead to show a specific value.

  • Proposed in the paper is an agent based and object-oriented methodology to create a virtual logistics support system model. The proposed virtual logistics support system model consists of three types of objects: the logistics force agent model(static model), the military supplies transport manager model(function model), the military supplies state manager model(dynamic model). A logistic force agent model consists of two agent: main function agent and function agent. To improve the reusability and composability of a logistics force agent model, the function agent is designed to adapt to different logistics force agent configuration. A military supplies transport manager is agent that get information about supply route, make decisions based on decision variables, which are maintained by the military supplies state manager, and transport military supplies. A military supplies state manager is requested military supplies from logistics force agent, provide decision variables such as the capacity, order of priority. For the implementation of the proposed virtual logistics force agent model, this paper employs Discrete Event Systems Specification(DEVS) formalism.

  • As the mobile telecommunications service market grows rapidly, interconnection opportunities from the fixed network to the mobile network increase and the land-to-mobile (LM) interconnection charge becomes critical factor in competition between fixed and mobile telecommunications service providers. This paper aims to evaluate the LM interconnection charge level in Korea in comparison with those of 36 foreign countries and suggest the regression model for the LM interconnection charge. Based on the regression analysis, we found that regulation, GDP per capita, wire telephone penetration, liberalization are identified as significantly affecting factors on the LM interconnection charge level, and the level of the LM interconnection charge is comparatively low.
