Information and Information processing systems must maintain a certain level of security during the total life cycle of Information. To maintain a certain level of security, security management processes are applied to software, automobile development, and the U.S. federal government information system over a life cycle, but theme of no similar security management process in Korea. This paper proposes a Korean-style security risk management framework to maintain a certain level of security in the total life cycle of information and information processing system in the defense sector. By applied to the defense field, we intend to present the direction of defense security work in the future and induce an shift in security paradigm.

Currently, the delayed compensation system, which does not reflect the R&D characteristics of the defense industry, is being applied, causing problems such as worsening management of defense companies and delayed power generation. The purpose of this study is to contribute to the development of the defense industry and the efficient promotion of combat capability by studying the improvement plan of the delayed compensation system reflecting the R&D characteristics of the defense industry. The research analyzed the defense industry R&D characteristics, national R&D, delayed compensation rate, reduction and exemption procedures and existing studies. Further, the Delphi technique was applied based on the status of the delayed compensation and the analysis of the cause of delay. It has been studied that it is not appropriate to apply the 'manufacturing and purchasing' standard of commercial products to defense industry R&D where the latest technology is applied and the success is unclear. Four measures were drawn to prevent delays, including the selection of excellent technology companies, and three measures to reduce delay compensation and apply differentials for rational treatment in case of delays. Just as the defense industry R&D is carried out under the Defense Acquisition Program Act due to the nature of the R&D industry, the defense industry will develop if the delayed compensation system is improved to reflect the R&D characteristics of the defense industry, and it will contribute to the acquisition of an efficient and economic weapons system.

The national defense electronic procurement system is an information system supporting DAPA, services (Army, Navy and Air Force), and the procurement companies in the electronic bidding. It has contributed greatly to improving the efficiency of the national defense electronic procurement process by providing various information services based on inter-operation among the related parties. However the national defense electronic procurement system is expected to be upgraded to the next version in accord with rapidly evolving infrastructure based on high technology and increasing various communication channels. This paper investigates the satisfaction level of the system users and proposes directions for the next-generation procurement portal.

The Korean navy has made many efforts to apply the concepts of PLM (Product Lifecycle Management) and M&S to its naval design and production. However, most of the efforts that have being applied to some acquisition processes, focused only on the element technologies without information models and data frameworks. This study discusses an information model of naval ships for advanced naval acquisitions. We introduce a naval ship product model, and it refers to the DPD (Distributed Product Description) concept of SBA (Simulation-Based Acquisition). To realize the product model concept, we design a data architecture and develop a Product Model Management System (PMMS) based on a PDM System. It is validated through the case study of building the product model of the battle ship that the PMMS has the applicability to effectively manage the naval ship acquisition data on the basis of a 3D product model.

This study aims to develop an approach to construct IWSDB for National Defense CALS. Along with the introduction of Korean version of CALS conception, it is essential to analyze the national defense system with a new information technology for the construction of IWSDB. A long-tenn goal of CALS is to construct fully Integrated Data Environment (IDE) and establish IWSDB for the application of CALS conception to the life cycle management of weapon system. IWSDB is a set of databases that contain digital data. It supports common interface of data objects and databases throughout the life cycle management of weapon system, including design, engineering, analysis, manufacturing, operation, and logistics. etc. The goal of this study is threefold. First, we propose a right direction for the establishment of Integrated Data Environment. For the integrated database technology, we use the five schema architecture and the distributed object oriented technology that will lead to the "share of data." Second, we present the most effective IWSDB architecture for defense CALS, which will provide the efficient data sharing by business process modeling. Third, we suggest that IWSDB should be constructed based on the process which is related to the acquisition and logistics of weapon system for the national defense, and at the same time it should be implemented with GITIS for government agencies and CITIS for the industries in order to obtain the efficient data sharing.

Although defense standardization is recently becoming more and more active, there are still many obstacles to achieve attainments as planned. On the other hand, national standardization already has been applied as a mandatory rule in the overall industries and R&D programs and is well supported by systematic and specialized national basis. Furthermore, advanced countries, such as U.S.A., England and NATO, are considering defense standardization as a essential element to achieve low cost and highly efficient acquisition system and to enhance interoperability among the allied forces. This study aims to form public opinion in support of importance of defense standardization and to provide the vision and various implementation tasks for improving defense standardization outcome.

RAM(Reliability, Availability and Maintainability) is one of the important indicators to show the performance of weapon systems. For analyzing RAM characteristics, RAM simulation is useful and powerful as mathematical techniques. However, it is necessary to build the simulation model to express about the operation environment of weapon systems, and obtain detail input data for reliability and maintainability about the system to get accurate results by RAM simulation. In this paper, we propose a procedure to analyze RAM of the searching system consisting in weapon systems by RAM simulation and we estimate searching system availability by a commercial simulation program, AvSim.

Purpose: Simple part or equipment is necessary TRA(Technology Readiness Assessment) or MRA(Manufacturing Readiness Assessment). But sole maturity like TRA, MRA has limit complex systems or SoS(System of System). Especially complex weapon system need from the System Maturity Point of view. This research shows necessity of SRA(System Readiness Assessment). Methods: In case of complex systems, it is essential to SRA(System Readiness Assessment). For the purpose of calculating SRL(System Readiness Level), TRL and IRL must be calculated. And then SRL can obtain know from equation of TRL and IRL. To prove SRA effectiveness, it is calculated SRL of JTDLS(Joint Tactical DataLink System) programs. Results: SRA procedure is proposed and case study shows as examples of JTDLS programs. Although result of TRA is TRL6, result of SRA is not 0.6. From this research, we can know necessity of SRA. Especially complex systems or SoS(System of System) is essential to SRA. Conclusion: SRA(System Readiness Assessment) is required to overcome limitation of sole maturity and to achieve a successful acquisition of high quality weapon system. This research intended to suggest SRA procedure and case study in complex defense system.
