Recently, the acquisition environment of the Korean defense weapon system is emphasizing more the importance of cost analysis in terms of efficient execution for defense acquisition budget. While cost analysis, however, is emphasized in law and process, its infrastructures are still insufficient We have been using computerized cost models to obtain an estimate at early phase of project. But those models have been developed by foreign companies, and so they have many limitations when using in Korean defense environment. For this reason, it began to sympathize that we need the development of the Korean version cost estimation model suitable for our defense industry environment, and now many studies are proceeding. In this study, we suggest Cost Estimating Relationships(CERs) developing methodologies which is key logics of Korean version cost estimation model. Especially, we proposed a new CER's development process depending upon data characteristics such as, multicolinearity, outlier, small samples and heteroscedasticity. Also, we presented a case study for artillery weapon system using these methods we developed. We find that these CERs could be verified through theoretical methods.

Purpose: In this research, we develop an effectiveness analysis simulation model using Agent Based Modeling with Communication Effects for the development of a new weapon system. Methods: To describe the future battlefield that has more complexity, we develop Agent Based Modeling to describe communication Effects. We use the communication theory (Path-Loss Model) and the real map. Results: We have compared simulation model with real map and simulation model without real map. The Blue Survival Ratio of simulation model with real map is worse than one without real map since the performance of communication gets lower. Conclusion: There are many studies about the effectiveness analysis of a weapon system. Most of previous researches assumed no communication error. In the real world, however, it's not appropriate assumption. Therefore, this study considers the communication error and shows that it is important factor in the effectiveness analysis.

In general, credibility for some analysis results is very important to most decision makers. Especially, it is even more critical for military commander to choose the best course of action by using the simulation results when he want to decide to allocate his available weapon system assets. Therefore, improving the credibility of simulation output is one of the key issues in military research fields. In this paper, we proposed a new simulation framework to improve the credibility of weapon's effectiveness analysis results. Multi-agent based simulation tool is applied and compare current process to the proposed framework. We also showed an example case when a communication repeaters are installed to expand the commanding area scope. The example clearly tells why this new simulation framework is more efficient and improve the credibility of simulation results.

This paper presents a developmental approach undertaken by Asiana Airlines to implement computerized reservation system (CRS), Asiana Airlines is a new entrant into the once monopolized airline business in Korea. As a new entrant, it was absolutely necessary to develop CRS fast to begin the business in a relatively short period of time. By taking the risk of choosing Airline Control System which no airlines has yet implemented CRS with, Asiana Airlines was able to shorten development time considerably as well as integrate CRS with internal management information systems. This enhances system flexibility greatly. It is initially viewed that developing CRS is not to get competitive advantage but to overcome competitive disadvantage at Asiana Airlines. The paper also surveys the changing environment of CRS in general and the future implementation plan for ARTIS(Asiana Airline Reservation and Travel Information System) to be more of a competitive weapon in increasingly competitive international air travel market.

In the performance analysis of a weapon system, the combat effectiveness is difficult to go beyond the conceptual level in the early stages of development. This is especially true in the case of new concept of weapon system that has never existed before. In this study, with the aim of analyzing the effectiveness of small personal guided weapons, the design of the warhead and the detonation test were carried out and the results were analyzed. Afterwards, trajectory of fragments were calculated from the results, and it is applied to the anti-personnel effectiveness logic which is a part of combat simulation tool. At the same time, delivery accuracy logic was constructed from Monte-Carlo simulation with 6-DOF trajectory model. Subsequent simulated experiments were conducted with test scenarios to confirm the simulation logic reflecting the results of the warhead detonation tests for verifying the simulation approach of weapon systems, and it was confirmed that the simulation logic incorporating the results of the warhead detonation tests functioned properly.

Cyberattacks on information systems used by applications related to weapon system and organizations associated with national defense put national security at risk. To reduce these threats, continuous efforts such as applying secure coding from the development stage or managing detected vulnerabilities systematically are being made. It also analyzes and detects vulnerabilities by using various analysis tools, eliminates at the development stage, and removes from developed applications. However, vulnerability analysis tools cause problems such as undetected, false positives, and overdetected, making accurate vulnerability detection difficult. In this paper, we propose a new vulnerability detection method to solve these problems, which can assess the risk of certain applications and create and manage secured application with this data.

North Korea has steadily implemented defense reforms to strengthen its national defense capabilities, and in particular, has made military technology development and military industrial capability strengthening as the focus of national defense reform. North Korea's defense reform ultimately aimed at securing nuclear posture, and as technical achievements accumulated in the Kim Jung-Un era, it led to the development of military strength such as hydrogen bombs and ICBM/SLBM. Having secured nuclear capability, North Korea is also pursuing a symmetricality in the conventional military strength by securing a strategic advantage by pursuing the modernization of the conventional weapon systems through defense reform again. Up to now, North Korea's defense reform has succeeded in establishing a new ruling system for Kim Jung-Un and creating a driving force for negotiations with the United States.

The Army, Navy, and Air Force are making various efforts to develop a weapon system that incorporates the 4th industrial revolution technology so that it can be used in multi-domain operations. In order to effectively demonstrate the integrated combat power through the weapon system to which the new technology is applied, it is necessary to establish a network environment in which each weapon system can transmit and receive information smoothly. For this, it is essential to analyze the Information Exchange Requirement(IER) of each weapon system, but many IER analysis studies did not sufficiently reflect the various considerations of the actual tactical network. Therefore, this study closely analyzes the research methods and results of the existing information exchange requirements analysis studies. In IER analysis, the size of the message itself, the size of the network protocol header, the transmission/reception structure of the tactical network, the information distribution process, and the message occurrence frequency. In order to be able to use it for future IER prediction, we present a technique for calculating the information exchange requirement as a probability distribution using the Poisson distribution and the probability generating function. In order to prove the validity of this technique, the results of the probability distribution calculation using the message list and network topology samples are compared with the simulation results using Network Simulator 2.

Given the growing interest in damage control training for the naval ships and their organizations, expectations for a new concept of training program have also increased. The existing training programs and its concept focus on training crew to be more proficient and skilled so that they can respond better to damage situations, i.e., fires and flooding. This paper suggests a development procedure of damage control training scenarios using the survivability analysis results as a new concept of damage control training programs employing advanced systems such as damage control console, automation system, and kill cards. This approach could help the decision maker not only enhance his or her capability but also improve the reacting capability of crew members for complex situations induced by a weapon hit.

This article aims to critically review recent U. S. RMA-centered theories of warfare having prevailed after the 1991-92 Gulf War upon which the current ROKA military transformation project, the Vision 2020, largely based. In order to evaluate validity as a universal warfighing theory of NCW (Network Centric Warfare) and EBO (Effects-Based Operations), this article reviews the intrinsic strength and weakness of the theories as well as results of several recent wars that the U. S. Army conducted based on doctrines derived form such theories, In addition, this article examines the impact of certain military technology or weapon system in some well-known historical wars to draw lessons regarding the relationship between technology(weapon system) and military victory. Historical examples has shown that victories in war were not achieved by new technologies alone in most cases. Rather military victories tended to owe to combination of new technology, original doctrine and well conceived organization. Although the U. S. Armed Forces showed brilliant records of operational successes anchored on the system of PGMs and NCW concepts in Iraq (1991-92; 2003) and Afghanistan (2001-02), it must be pointed out that the operational successes did not bring about political ones in cases of Iraq and Afghanistan. It reminds us of perils of too technologically tilted approach to the conduct of war. In sum, one ought to recognize that superior technology nowadays became a necessary condition of success but is not yet a sufficient condition, the ROKA needs to be abreast with development trends of military technologies and related theoretical concepts, it need not too be in a hurry in adopting cutting edged war-making technologies at the expense of large amount of budget. The essay recommends for the ROKA several basic requirements for coping with conduct of future wars as well as establishing a 'Korean style military thought'; (1) Recognition of importance of technology in conduct of war; (2) Imposition of officer self-study hours in working days; (3) Establishing a lifestyle of military professionalism in the Korean officer corps; (4) Setting up small or large groups of think-tanks that are specialized in army doctrinal formulation.
