Although the current evaluation system has been revised four times since it was revised in 1996, it is insufficient to utilize it as a basis for predicting the performance degradation from the long-term viewpoint and prioritization decision for the budget input due to the evaluation system limited to securing the structural safety. Therefore, this study proposes a new evaluation system suitable for the performance evaluation of conventional (ASSM) tunnels among the various types of existing road tunnels using Delphi technique and AHP technique. Since the existing evaluation systems and evaluation items in domestic and overseas are limited in scope of evaluation criteria, the survey was conducted in conjunction with closed questionnaires on existing items and open questionnaires for eliciting new items. The validity of the questionnaire results were verified and the performance evaluation factors suitable for conventional (ASSM) tunnels were derived. After calculating weighted value of the derived evaluation item using AHP technique, a new evaluation system is proposed to meet the characteristics of the ASSM tunnel, so that they can be used as reference materials for revising and supplementing detailed guidelines of performance evaluation in the future.

The purpose of current tunnel maintenance system in South Korea is safety-based maintenance system for accident prevention, So it is difficult to conduct a strategic maintenance. The development of a new maintenance system can lead to effective investment of limited financial and it's effort is still in progress. In this study, to develop a performance-based assessment method, indexes for assessment are derived taking into account the safety, durability and serviceability. The indexes for performance-based assessment were selected by a literature analysis and a delphi survey. Then the importance among indexes were calculated by the AHP analysis.

최근의 전장 환경은 전투 공간에서 파악 가능한 모든 요소를 효과적으로 연계하여 정보의 우월성을 기반으로 전투력을 향상시키는 네트워크 중심전 체제로 진화하고 있다. 이에 우리 군은 네트워크 중심 전장 환경의 핵심 요소로서 전술다대역다기능무전기를 개발해왔으며, 기존 아날로그 방식 무전기를 기반으로 네트워크를 구성하여 운용하는 체계에 순차적으로 적용될 예정이다. 이는 지상 무기체계도 예외는 아니다. 이러한 상황에 따라, 본 논문에서는 지상 무기체계 환경에서 전술다대역다기능무전기의 성능 평가 및 분석을 수행한다. 성능 평가에서는 실제 전술다대역다기능무전기를 기반으로 지휘통제체계와 무장통제장치 간의 무선 통신환경을 모의 구성하여 성능 시험을 수행하였으며, 결과 분석을 통해 전술다대역다기능무전기의 지상 무기체계 적용 가능성을 확인한다.

The purpose of this study is to derive the need to improve the test and evaluation(T&E) performance system of the weapon systems to which advanced science and technology is applied, evaluate priorities, and present development plans. T&E of Al-based weapon systems through a literature research and case analysis on changes in the T&E environment for weapon system, 11 detailed evaluation items were derived from the in terms of the T&E system, structure, and technology. Al-based weapon system test evaluation should be performed in parallel with data-based performance evaluation and actual T&E, and performance measurement using a separate T&E data set is required for AI models performance evaluation. As a result of analyzing the importance of T&E through AHP analysis, the order of T&E system-technology-structure was evaluated, and the priority of detailed evaluation items was evaluated in the order of T&E result judgment-T&E organization and expert training-scientific T&E. For evaluation items with high priority, measures to improve the T&E performance system were presented.

The Test and Evaluation (T&E) system became more important due to its advancement and complexity of the weapon system. Time and cost saving T&E related studies are in progress mainly with advanced countries. By utilizing the Modeling and Simulation (M&S) technology recently, we may save time and money. Also, overcome security and safety limitations. There are many M&S based research activities in South Korea but it is way behind of the system that some countries already have developed. i.e.; United States. This area of study requires new way of developing strategies in the T&E system of Korea. This study is to design the Operational T&E system for weapon systems based on modeling of processes. And we modeled the processes of operational performance evaluation through utilizing resources and performance modules of weapon systems and combined it with the simulation engine for 3D visualization. Through this, we propose the Operational T&E system for weapon systems based on modeling of processes that represent operational performances visually.

This paper proposes potentialities of constructing the information system for earthquake hazard management which can manage and analyse earthquake risk and hazard systematically. The experimental results as well as architectural structure investment data for seismicity assessment are built in database and connected with GIS for assessing earthquake safety of building in urban area. For earthquake-resistant performance assessment, we collected and classified building structural data according to assessment criteria using building register, architectural map, digital map, and then complemented database with field survey data. We also suggest GIS-based information system can cope with and manage earthquake hazard effectively, as evaluating earthquake risk by performing detailed earthquake-resistant assessment and determining final assessment scores. The assessment should be processed quickly and accurately by integrating the earthquake hazard information management system with modularization of assessment procedure and method in the future.

Given the trend of increased apartment buildings and high-rise buildings, the maintenance of apartment buildings has been set a higher value. For this reason, a total performance evaluation model of the existing buildings has recently been developed. But, it has a lack of the management work analysis. The purpose of this study, therefore, is the management work analysis for items selection of maintenance performance evaluation of apartment buildings. Candidate items of Maintenance performance evaluation was made with the existing literature and business system analysis. Easy, systemicity of performance evaluation supplemented doing question to academic experts and housing managers. Finally decided maintenance performance evaluation items are to classify 14 administrative and 15 technical items.

In National Defense field, the importance of M&S and T&E has been increased due to complexity of modern Weapon System. And research reducing time and cost is being conducted continually on using limited resources efficiently. In the existing research, Weapon System's Performance Evaluation System using the Process-based method has been in progress. But, Objective basis or scientific method is insufficient in selecting appropriate function of a target to performance evaluation. Due to this, it's difficult to select functions suitable to the situation in same type. Also, Requirements of user and interrelation of evaluation factors can't be reflected systematically. In this research, it proposes the method to reflecting requirements of user, interrelation of elements in realistic situation for selecting evaluation object in Performance Evaluation Simulation. First, Evaluation Objects is selected using ANP which is multi-criterion decision making method. Second, decision support system is constructed using Programming Language(C#) based on the research result.

CIWS의 성능 및 유용성에 관한 토론은 안전한 실제시험의 구상이 어려우며, 성능입증자료가 부족하다. 유도탄이 안전하게 목표지점을 향해 접근할때 항상 대유도탄 방어체계가 준비되도록 제작자들은 요구받고 있다. 장래의 고객이 미 해군의 지연된 Goalkeeper체계의 평가결과를 아는 것은 가치가 있는 일이다. 그러나 미 해군은 Phalanx 체계에 대한 엑조세(Exocet)와 하-푼(Harpoon) 유도탄의 시험결과를 비밀에 부치고 있다.
