Preventive maintenance(PM) is an action taken on a repairable system while it is still operating, which needs to be carried out in order to keep the system at the desired level of successful operation. In this paper, we consider a Bayesian approach to determine an optimal periodic preventive maintenance policy. When the failure time is Weibull distribution with uncertain parameters, a Bayesian approach is established. Some numerical examples are presented for illustrative purpose.

Today, as interest in the importance of urban parks increases, many citied internationally are actively creating small parks, but their maintenance systems remain ineffective. Accordingly, in this study, the limitations and problems in the operation and management of urban parks were derived by examining previous studies on overall urban park maintenance and management. Based on this, the study tried to understand the actual state of maintenance and management of small parks through data surveys and field surveys related to budget execution on case sites. Then, we sought to clarify the actual state of maintenance and management of small parks through data surveys and field surveys regarding the budget execution of case sites as a basis for research to prepare an efficient and systematic improvement plan for the maintenance management system of city parks.

It is very important to manage efficient data for safety and maintenance of those constructs. Estimation for structural safety can be evaluated by using data that surveys various structural durability and safety elements. so, it should be based on synthetic and efficient data that includes a variety of related safety elements obtained from a structure. It will subsequently be managed properly and economically. Accordingly, we will approach efficient maintenance management using a Geographic Information System (GIS) with data from structural-safety diagnosis and a Global Positioning System (GPS). In this study, we noted that by using the data that measures the factors (crack, incline, settlement etc.) of various structures as evaluate safety degree. And the horizontal coordinate variation/time of structure was monitored using the GPS easily.

현재 국내외 BIM을 도입한 사회기반시설 적용 사례는 BIM 시각화를 기반으로 하는 설계 및 시공단계에 제한되며 효율적 운영을 위한 설계, 시공 정보 활용 방안에 대한 연구는 매우 미미하다. 본 연구는 최근 국내 경제 발전에 많은 기여를 하고 있는 산업설비군 중 운영 및 유지관리 능력 향상이 필요한 하수처리시설을 대상으로 BIM 기반 통합 유지관리 프로토타입 시스템을 개발하였다. 본 연구에 사용된 주요 연구 방법으로는 시스템 개발 순서에 따라 진행하였으며, 최종적으로 개발된 프로토타입 시스템의 현업 적용 가능성을 판단하기 위하여 4가지의 대표적 유지관리 시나리오를 제안하고 산출물을 통해서 문제 해결이 가능함을 보여준다. 최근 상하수도시설의 자산관리 개념 도입 노력과 유역기반 운영 및 유지관리의 정책 및 제도 적 변화, 그리고 국내 상하수도 기술력의 해외시장 진출 필요에 따른 운영 및 유지관리 능력 고도화를 위해 본 연구결과가 일조할 수 있기를 기대해 본다.

The purpose of this study is to analyze elemental maintenance costs for educational buildings. The adapted research method selected three school buildings in Seoul as BTL projects. On the basis of the selected case, the study suggested a model to establish a system for each parts and to estimate analyzed maintenance costs through that system. According to the analysis, the study proposed a partial maintenance costs standard and analyzed proper maintenance costs. The results of this study are as follows 1) The system is divided into 8 large-groups and 24 small-groups for the analysis elemental maintenance costs. 2) The average rations followed by analysis of partial maintenance costs of the three school buildings are as followings, the total maintenance costs are analyzed 3,992 million won and each part of average rations is exterior of building 10.9%, interior of building 41.58%, electricity & fire fighting facility 14.22%, water supply & healthy facility 11.39%, heating & water supply facility 12.93%, landscape 6.3%, civil engineering works 2.69%.

This study deals with the procedure of safety improvement, productivity increase ,and tact-time reduction through setting up the system about preventive maintenance. Actually, it is hard to establish and carry out preventive maintenance, even though we recognize the importance of the system concerning time, cost, labor, and so forth. In this study in the viewpoint of cost we are for achieving maximum efficiency by change and reduction of planning process adapted to the special work group. At first we briefly will mention the kind ,the necessity ,and the concept of preventive maintenance ,and then divide the equipment used in the assembly line into the two whether it is necessary or not by way of estimating the breakdown loss ,comparing with general establishment of preventive maintenance and modifying it to the case. At the second step we will establish the operation system of plan management related to production and quality in the special case. Check period and category will be set by dividing the assembly equipment into LCL and Focus in the third step. The forth step will contain the operation procedure in detail. And then we must make check and repair record periodically. Finally, on the basis of the record the selection of checking of significance will be conducted. This results in safety improvement, tact time reduction, and productivity improvement.
