This paper provides a simple microeconomic model of terrorist attcks and anti-terrorism policies. The terrorists can be characterised as rational actors, choosing between legal activities and terrorist activities to promote their political goals. Since their resources are limited, one can think of anti-terrorist policies by examining how such policies affect the objectives and constraints of terrorists. Deterrence policy seeks to reduce terrorist attacks by raising the cost of undertaking terrorist acts. Proactive policy aims at preventing attacks by destroying terrorists' resources (fund, personnel, leadership). This paper suggests another type of anti-terrorist policy which is to reduce the benefits of (or in other words, raising the opportunity costs of) terrorist acts. Such a policy is based on decentralisation in political decision-making and economic power.

A study for improvement of credibility on test & evaluation result of interoperability in battle management information system which focused in C4I systems is very essential in rapid change of battle field environment. Realization of effective operation process with integration of developed IT also core factor for reducing of operational response time such as information gathering from sensor to shooter, time for commander's decision making. Therefore, by required to meet of high technical T&E, meet of complex software's user requirement, long-term system development period, system integration ability's request by various linkage of systems, it is high a M&S dependency to optimal performance, interpoerability's guarantee. Especially credibility on test & evaluation using M&S is very important. This paper will propse a VV&A applied methods using other VV&A case to improve credibility of M&S on test & evaluation.

본 연구는 미래 정보전에 대비하기 위한 대책의 일환으로 전군적 차원에서 체계적인 정보보호 업무 수행체계를 수립하기 위한 방안을 제시하기 위한 것이다. 미국, 일본 등 선진국들은 미래 정보전에 대처할 수 있는 새로운 안보전략을 수립하다. 그러나 한국군은 비록 정보화 사업을 꾸준히 추진하여 왔으나 정보전 위협에 대한 대비는 매우 미흡한 실정이다. 본 연구는 이러한 취약점에 대비하고자 국방정보체계 분야 전문가에 의한 그룹의사결정기법을 활용하여 국방정보 보호 업무 관리 구조 방안을 도출하여 제시하였다. 본 연구에서 제시하는 업무수행 구조에 따라 정보보호업무 구조를 정립하고 수행한다면 보다 완벽한 정보보호 대책을 마련할 수 있을 것이다.

Considerable research has concentrated on medium-range production planning model in that it can contain long and short-term decision making in contents. Since medium-range production planning deals in situations with setup time or/and costs, solution methodology is classified by (1) optimization method using a sort of integer programming approach and network formulation (2) heuristic method offering an computationally easy, approximate solution. But, solution methodology is different in type of demand generation, existence of capacity and dependant demand. Therefore this paper reviewed the medium range production planning according to above mentioned three factors, and suggested for further work direction.

Cyber threats can bypass existing cyber-protection systems and are rapidly developing by exploiting new technologies such as artificial intelligence. In order to respond to such cyber threats, it is important to improve the ability to detect unknown cyber threats by correlating heterogeneous cyber protection systems. In this paper, to enhance cyber-attack response capabilities, we proposed command and control that enables rapid decision-making and response before the attack objectives are achieved, using Lockheed Martin's cyber kill chain and MITRE ATT&CK to analyze the purpose and intention of the attacker.

An aircraft collision accident is a disaster that causes great losses of inventories and lives. Though a collision avoidance warning function is provided automatically to pilots in the aircrafts by the enhancement of the aircraft capability, achieving fast decision-making to escape a collision situation is a complex and dangerous work for pilots. If an in-flight collision situation is controlled by the air traffic control system which monitors all airplanes in the air, it would be more efficient to prevent in-flight collisions because it can handle the emergency before the pilot's action. In this paper, we develop the collision avoidance warning function in the air traffic control system. Specifically, we design and implement the five stages of the collision avoidance function, and propose a visualization method which could effectively provide the operators with the trajectories and altitudes of the aircrafts in a collision situation. By developing an in-flight collision warning function in the air traffic control system that visualizes flight patterns through the state transition data of in-flight aircrafts on the flight path lines, it can effectively prevent in-flight collisions with traffic alerts. The developed function allows operators to effectively select and control the aircraft in a collision situation by providing the operators with the expected collision time, the relative distance, and the relative altitude while assessing the level of alert, and visualizing the alert information which includes the Attention-Warning-Alert phase via embodying the TCAS standard. With the developed function the air traffic control system could sense an in-flight collision situation before the pilot's decision-making moment.

한반도 안보상황에서 주변국들에 의한 EMP 위협이 고조되는 상황에서 EMP 방호시설은 군의 작전수행능력을 보장할 수 있는 매우 중요한 수단이다. 이러한 EMP 방호시설은 작전을 수행하는 부대의 다양한 요소들을 종합적 고려하여 구축하여야 한다. 하지만 현 군 관의 EMP 방호기준은 80dB의 일률적인 차폐효율만을 요구하고 있다. 본 연구에서는 전문가 집단의 의견을 통해 객관적이고 통계적 방법을 사용하여 방호요구수준의 고려사항을 재선정하고자 한다. 연구방법은 델파이기법을 사용하였으며, 53명의 EMP방호 설계기준과 관련 있는 전문가들을 선정하였다. 1차 설문은 EMP 방호의 적정수준에 대하여 조사하였고, 2차 설문은 방호대책 수립시 고려요소에 대하여 분석하였다. 채택된 전문가의 의견에 대해 요인분석을 실시한 결과, EMP 방호요구수준 설정시 METT+TC 요소를 고려하여야 한다는 것을 확인하였다.

Both the neural network classifier utilizing multi-layer perceptron and the linear tree classifier composed of hierarchically structured linear discriminating functions can form arbitrarily complex decision boundaries in the feature space and have very similar decision making processes. In this paper, a new method for automatically choosing the number of neurons in the hidden layers and for initalzing the connection weights between the layres and its supporting theory are presented by mapping the sequential structure of the linear tree classifier to the parallel structure of the neural networks having one or two hidden layers. Experimental results on the real data obtained from the military ship images show that this method is effective, and that three exists no siginificant difference in the classification acuracy of both classifiers.

In this paper, we propose a data envelopment analysis (DEA) and analytic hierarchy process (AHP) integrated model to improve the selection process in the acquisition of a weapon system which is the key component to the success of the project. In particular, we applied DEA in the first stage to choose a frontier group among the candidates in the selection process of the next-generation fighter system (the 3rd FX) in Korea. Then, by using the Delphi technique, we surveyed military experts and applied AHP to determine the best choice among the candidates. The results of the study match the actual decision made by the Korean government in the weapon system acquisition. The results of the proposed DEA-AHP integrated method in the selection of the next-generation fighter systems in Korea demonstrate the usefulness of the method. In this paper, we also discuss the future implications of the proposed model.

Change detection using aerial and satellite images is one of the important research topics in photogrammetry and image interpretation. It is of particular importance especially in the fields of military, political and administrative affairs. When there is a need to detect changes in multi-temporal images, the most efficient methods for change detection and thresholds of change/no change area need to be chosen. Also, the images obtained from the various methods need to be analyzed. To do so, we need a system that can support our decision making process. Therefore, in this paper, we propose the Decision Support System for Change Detection. This system is composed of Data Base, Model Base and Graphic User Interface(GUI). Data base is a compilation of previous change detection results, and Model Base comprise of numerous operations. The data can be input and have the results of change detection analyzed by using GUI. In this paper, we will explain the entire operation of the system and demonstrate the level of its effectiveness.
