Visualization of construction process simulation and physical modeling were considered to overcome the limitations of current graphical simulation. The output of discrete-event simulation programs which are the most common mathematical statistical simulation tool for construction processes were analyzed for the visualization of earthmoving process that dealing with objects without fixed. Object-oriented models for equipment, material and work environments were devised to effectively visualize the numerical simulation results of the working time, the queuing time as well as the amount resources etc. The oscillation of the crane's cable and the lifted material that should be considered to rationally modeled and simulated by construction graphical simulation. The derived equation of motion was solved by numerical analysis procedure. Then obtained results was used for physical modeling.

자연재난은 각각의 유형별로 발생 특성이 다양하고, 피해 유형도 상이하기에 재난 발생 시 재난 특성에 따른 최적 자원의 비축 및 동원이 필요하다. 하지만, 재난관리자원은 종류가 다양하고 요구 비축량이 많으며, 재난유형별로 발생특성이 다양하고 피해유형도 상이하기 때문에 모든 자원을 비축하고 활용하기에는 어려움이 따른다. 따라서 재난특성에 맞는 필요 자원의 비축을 통한 효율적인 재난관리자원 운영 및 관리체계 마련이 필요하다. 특히, 침수관련 재난(호우, 태풍, 풍랑)의 경우 과거 20년(2001년~2020년)동안 발생 건수는 282건으로 같은 기간 발생한 413건의 자연재난 중 68%를 차지할 만큼 침수 대응에 따른 필요 자원의 분석이 필요하지만, 관련 자원의 운영현황 및 발생한 문제점에 대한 분석은 미흡한 실정이다. 이에 본 연구에서는 과거 20년(2001년~2020년)동안 발생한 침수관련 재난(호우, 태풍, 풍랑)발생 시 동원된 재난관리자원 사례를 분석하였다. 재해연보, 관련 백서 및 보고서 등의 수집 및 분석을 통해 침수 발생 시 동원된 장비, 자재를 분석하였으며, 자원동원 시 발생하는 문제점을 자원비축, 자원능력, 자원활용, 대응시간으로 구분할 수 있었다. 본 연구는 과거 발생한 침수관련 재난에 대하여 재난관리자원의 동원 사례와 시사점 및 문제점을 도출한 점에서 그 의미가 있으며, 향후 침수 관련 재난 발생 시 자원의 효율적인 비축 및 관리, 동원 및 응원 등 효율적 운영방안 수립에 활용할 수 있을 것으로 기대된다.

Currently the automobile parts manufacturing industry of most, it is difficult in the automobile part development and purchase and production management. And when new regulation it will develop this automobile parts and changing design, it is difficult in new registration and history management. Automatic history management and DB construction about automobile parts is in great demand. The purpose of paper is a design of data retrieval and real-time production integration management for automobile parts. Automatic data update is accomplished as input material changing process for design data change and integration management of history information about parts is possible when input the name of an part and the number of an part.

Recently, the scale and technical complexity of agricultural production has been growing. Therefore, agricultural facilities are being gradually diversified, expanded, and made more complex. To furnish Korea's agricultural industry with international competitiveness, it is thus necessary to introduce new management techniques. The PCM (procurement-construction-maintenance) information management system for agricultural facilities is established by setting up its WBS (work breakdown structure). In this study, the WBS of a facility such as facility, space, element, works, and resources is analyzed. Following this analysts, a WBS of an agricultural facility that is appropriate for the PCM information system of an agricultural facility, is proposed by deriving it from actual WBS.

한정된 자재 및 에너지를 유효히 활용하여 고품질의 식물생산을 위해서는 고도의 환경제어와 적절한 관리작업이 필요하다. 이를 실시하기 위해서는 환경계측제어나 식물생육에 항상 주의를 기울일 필요가 있으며 지속적인 주의력과 다수의 요인에 대한 종합적인 판단력이 불가피하다. 이를 위해 인력만으로 이것들을 실시하려고 하면 노력이 못미치어 불완전하게 되며, 또한 생산규모의 확대가 인건비 상승에 직접적으로 연관되어 규모화의 이점을 얻기 힘들다. (중략)

Recently, the Radio Frequency Identification(RFID) system has been growing with many promising features in technology and applications fields. Especially, a lot of efforts for the application of RFID system in the field of logistics management have been conducted. In addition, in logistics section of steel industry a remarkable efficiency can be attained by application of the RFID system. However, in the RFID system applied for the steel industry, lots of problems were found to be solved in recognition of the tags and antennas. This paper presents the feasibility of deploying RFID in the steel industry as a tool for reduction of the production cost. An application of the steel industry to RFID-based tracking management system was proposed. The results of this paper showed that the recognition rate of material input and output was found 100 percent and secured 99 percent of detection rate in the location. In conclusion, the proposed RFID-based tracking management system was approved superior to the existing system in terms of productivity.

Companies' efforts to find ways to reduce logistics costs for products and raw materials currently being brought in to produce products in all manufacturing processes are one of the biggest challenges, and the recent global recession has made logistics management even more important. This development technology limits the development of IN/OUT Bound truck logistics and dock management optimization system in the factory, especially by using UHF 900Mhz RFID radio frequency technology.

Manufacturer's competitiveness in the MRO industry, which is to stimulate the growth of the business-to-business e-commerce market, has recently become more important. A nuclear parts manufacturer was supplying products based on irregular demand from clients which differs from ordinary MRO business practices. The reason for this is the Nuclear Parts Manufacturer has fallen behind the e-commerce performance of other industries, and they lack global competitiveness due to the low efficiency of the individual companies within it. In this study, we developed an MRO based a-Marketplace system to minimize repetitive ordering of raw materials, lack of reusability and inefficiency of transaction processing which was a result of the former legacy business practice, In order to accomplish the purpose of this study, we implemented a web based automated CR system which considered the characteristics of the nuclear parts manufacturing: the system has sub modules such as ordering, product management, transaction management, warehousing and raw material handling. As a consequence of the system implementation, H corporate successfully automated ordering of raw materials, quotation processing and inventory management compared to the legacy business process, achieving increased efficiency by reducing wasteful resources.

GS E&C applies TPMS(Total Project Management System) to all construction projects. This system is applied to all overseas projects, it is successfully used not only GS E&C but also subcontractors, vendors and clients. TPMS collects data spontaneously that is used to each participant, improves effectiveness in construction projects and gives transparency to all participants while sharing same information. This paper is aimed to share successful case study focusing on document management system, and how to develop TPMS in the future.
