Systemic management is required at each phase of the C4I system life cycle to achieve information advantage in the battlefield through stable operation of the C4I system under the NCOE. In particular, the maintenance phase is the longest period of the C4I system life cycle, and it is easy to utilize and analyze data such as faults that occur during system operation. However, according to the previous research, the maintenance is evaluated as a phase in which the definition and management of comprehensive indicators are insufficient compared to other phase. In this paper, we propose the method of C4I Maintenance Priority decision using Maintenance metric. As a result of modifying the Naval Tactical C4I System's preventive maintenance cycle according to the priority, the total number of faults is reduced and the maintenance efficiency is improved.

In this paper, an information management system is developed to systematically maintain facilities which include AS/RS(Automatic Storage & Retrieval System). Stacker Crane, Tool Transport system and Machining Center in FMS pilot plant. It supports various activities such as periodical inspection, maintenance, management of daily operation time, analysis of existing condition and management of information related to facilities.

In order to build an effective management system for structures and to propose national policy and vision for advance of safety and maintenance management, 'Fundamental Scheme of Safety and Maintenance Management for Structures' has been established and promoted. As developed countries adopt preventive maintenance management, which is preventive as well as aggressive repair/strengthening for structures, it is needed to introduce life-cycle analysis method for improvement of economical efficiency. Therefore, this paper presents not only analysis of domestic conditions and problems related to system for safety and maintenance management, policies and costs for structures but an improvement plan.

Recently, many kinds of research has been actively developing for a standardization and information related to the construction works. These works include the general field of design, construction, supervision, maintenance and management on facilities. The works of database construction for a standardization and information were chiefly propelled centering around the present conditions related to the design, construction work. The field related to maintenance and management on facilities lags behind in the works of database construction. The establishment of standard classification system(SCS) on facilities and inspection data is most important among the things related to maintenance and management to have a efficiently maintenance and management. This paper suggests SCS on facilities and inspection data according to that of facilities. On the basis of SCS of facilities and inspection data, code work with classification system and input work for a data of maintenance and management was practised. The purpose of this paper is to suggest a kind of statistics data and investigate a characteristics of inspection using statistic data on tunnel structures

This study is aimed at developing a web-based management system of maintenance historical data, for effective maintenance performance and smooth exchange of information and communication between public facilities and public educational facilities managers. The current management state of maintenance historical data and its business process were investigated and analyzed, through interviewing with the persons in charge of managing each facility, by recognizing problems of maintenance historical data management that is able to be applied as a basis to judge facility deterioration and performance. In addition, this study suggests a maintenance historical data system of which DB may be applied to the practical business, by reflecting requests of the persons in charge of managing facilities, setting up the scope of system usage by facility, business phase and level of facility managers, and establishing a maintenance business process system.

Maintenance equipments, tools, manuals and documents are needed to maintain weapon systems. At the time, a lot of technical materials are maintained and used individually at various places and organizations. Thus, maintenance engineers can rot get the necessary informations quickly and the efficiency of maintenance is low. In this paper, first we analyze maintenance processes in weapon systems and define the total measure to evaluate the maintenance efficiency of weapon systems. Second, we propose an implementation procedure to integrated maintenance system.

This paper suggests a specific model that could efficiently improve the interaction and the interface between MES(Manufacturing Execution System) server and POP(Point of Production) terminal through electronic document server and electronic pen, bluetooth receiver and form paper in disassembly and process inspection works. The proposed model shows that the new method by electronic document automation system can more efficiently perform to reduce processing time for maintenance work, compared with the current approach by handwritten processing system. It is noted in case of the method by electronic document automation system that the effects of proposed model are as follows; (a) While the processing time per equipment for maintenance by the current method was 300 minutes, the processing time by the new method was 50 minutes. (b) While the processing error ratio by the current method was 20%, the error ratio by the new method was 1%.

Noise barrier is used for noise reduction method of traffic noise. The length and the total cost of that are increased in this national area. But, a maintenance management of noise barrier is not systematic, and the guideline of that is not prepared for maintenance mannual. The situations of existed installation and management of noise barriers installed at 3,619 positions were investigated by questionnarie and direct field survey. And comparisons with foreign management guideline of noise barrier were carried out. The results show that the improvement methods of maintenance management system such as practical checklist and required items for management of noise barrier were suggested.
