As delivery services market has grown the damage cases are also continuously increased. When using delivery services, Customers would not be compensated in any way. Perhaps worse, losing a cargo would create a great deal of trouble. Because the lack of evidence, they takes a lot of time to clarify who is responsible. To prevent these things, we must create, collect, maintain and confirm. In this paper, we introduce new delivery system with a trusted third party for non-repudiation services. Moreover, in damage case, we show that the proposed system is efficient and provide non-repudiation. Using sending and receiving codes, the proposed system identifies a responsible subject with quickness and clearness.

오늘날 경영환경은 운송수단의 발달과 정보통신 혁명 등으로 기업들의 급격한 글로벌화가 진행되고 있다. 글로벌한 환경속에서 다양한 고객의 요구를 대응하기 위해 다양한 상품과 서비스를 원하는 시간에 정확하고 합리적인 비용으로 고객에게 전달하기 위하여 많은 물류기업들이 끊임없는 노력을 경주하고 있다. 물류기업은 물류경쟁력을 확보하기 위해 여러 화주의 물량을 공동으로 보관 및 운송 서비스를 수행하는 물류공동화를 수행하거나 관련 물류기업간의 전문화를 통한 다양한 협업 모델을 도입하여 적용하고 있다. 그러나 IT부문의 관점에서 보면 일부 국제물류 등의 수출입 EDI 시스템을 공동으로 활용하거나 운송시스템을 대기업의 서비스사업자를 중심으로 시스템을 공유하는 것을 제외하며 IT시스템 관점에서의 협업 또는 IT공동화 체계는 거의 없는 실정이며, 오히려 물류기업간의 경쟁이 심화되면서 물류기업간의 상호 정보유출 등을 우려하여 매우 폐쇄적으로 운영하고 있는 실정이나 상대적으로 중소물류기업의 입장에서 보면 기업의 영세성 등으로 인해 거의 IT부문에 대한 투자나 활용이 거의 진행되지 못하는 문제점 또한 발생하고 있다. IT시스템을 공동으로 구축 및 활용함으로써 상호간의 비용 절감하고 IT시스템의 전략적 활용을 극대화 하기 위한 방안으로서 물류기업에서 IT공동화의 도입 방안을 제시하고자 한다. 먼저 금융권의 IT공동화 사례 및 국내외 물류관련 사례를 살펴보고, 물류IT공동화의 유사개념인 제4자 물류와 소프트웨어를 필요한 만큼을 필요한 시점에 서비스를 활용할 수 있는 모델인 ASP, SaaS, 클라우드 서비스 등을 비교함으로써 물류IT공동화의 도입 방안과 활용 방안을 제시 하였다.

The management of a panel block shop in a shipyard is a complex process that entails the largest amount of work and in which many decisions are involved. Shipbuilders have considered the process as a bottleneck since every panel for every ship and offshore hull structure must be processed through the shop. In order to maximize process productivity, simulation-based ship production execution system(SPEXS) is proposed for panel block operations utilising discrete-event simulation and simulated annealing. An application of panel block assembly shop, called SPEX-Panel supports production planners by general dispatching rules and metaheuristics to make better scheduling decisions on the shop floor. In addition, the system will help increase productivity in the yard with continuous improvement.

This paper aims to describe a case study of parametric interior design based on BIM (Building Information Modeling). As the practical use of BIM-based design grows, its influence expands into the field of interior architecture design. BIM makes possible to check various design plan, reach decision making in an effective way, and change design plan in an efficient method. Therefore, BIM is also promising field in interior architecture design. However, compared to other fields in architecture, engineering, and construction (AEC) industry, there have been less research and projects on BIM in the field of interior architecture. For increasing the feasibility of adapting BIM in interior architecture design, this paper describes a case study-projecting images for designing interior panels using parametric modeling. This process needs elaborate, delicate, and precise steps for harmonious output. For continuous use of building, users look forward to the design which variable and changeable according to user's preference and environment. Therefore, demand for parametric design in the interior design part such as panel pattern design for various decoration is growing. Treated process in this paper deals with an advanced phase which much effective in decreasing time consumption and useless part of process. Finally, this paper suggests the possibility of using BIM in the interior design process and field where BIM can be applied.

우편물량 처리에서 병목현상의 원인이 되고있는 수작업에 의한 순로구분 작업을 원활하고 신속하게 처리하며 집배원의 업무 부담을 경감시키기 위해 자동화가 시도되고 있다. 이러한 자동화된 순로구분기의 개발에 있어 순로구분에 필요한 주소 데이터 베이스를 관리하기 위해서는 각 배달지점에 대한 고유한 ID 부여가 필요하다. 따라서 본 논문에서는 아직 체계화되지 않은 한국 주소의 배달점 코드 설계 방안에 대해서 연구하였다. 먼저 해외 각국의 배달점 코드할당 방법을 알아보고, 배달점 코드의 기본 정의 및 설계 방향을 제시한다. 그리고 각 주소의 고유한 배달점 코드를 설계하는데 있어 여러 가지 방안을 제시하고 각 대안별 장단점 및 설계 방법을 제시하였으며 적합한 설계 방안을 선정하였다. 또한 기존의 주소체계뿐만 아니라 도입 예정인 새주소 체계와의 적합성도 고려하였다. 본 논문에서 제시한 우편번호 앞 3자리와 6자리의 일련번호를 연결한 배달점 코드가 현재의 한국 주소체계 뿐만 아니라 새주소 체계에도 적합할 것으로 판단된다. 마지막으로 몇 가지 적용 사례를 통한 제안한 방안들을 검증해 보았다.

To effectively control a vast amount of postal packages, we need the automatic system for extracting the address region from CCD scanner images. In this paper, we propose a address region extraction algorithm in the standard postal label. We used geometric characteristics of the underlying address regions and defined several criteria for fast detection of address regions. As a result, we accomplished a successful detection and classification of the postal package labels in real time.

In shipbuilding industry, there is conducting most of works by welding at the shipyard, and the volume of welding is increasing with international trends of green ships. Welding joint is guaranteed quality through non-destructive testing (NDT). The manual welding inspection report is produced by identifying the drawings designed, which results in losses the many workforce and occurs human errors. To solve these problems, this paper covers a system that reports on inspection information is automatically generation by input data based on shipbuilding-specific CAD. The developed system analyzes the shape data from drawings of modeling. Also, the system determines welding joints through expansion of the part boundary and generates tag numbers. In addition, it provides the function to automatically extract the information needed for inspection such as weld length, thickness and etc. We conducted test to verify the usefulness of the developed system and confirmed that the welding inspection information extracted through system matches the information shown in drawings of modeling.

Recently, BIM is used at several areas actively because of introduction of BIM in the construction industry. In particular, the recent many studies on activation of BIM information sharing is underway and it is the future direction of BIM. Moreover, it should be clearly realized. In the BIM levels of domestic construction phase, Interference Review, calculating volume estimates in part based on the active research is underway. However, still interested in reviewing building codes have relatively little interest. As BIM enabled, The methods of reviewing building codes should be transformed into a automated system by using information of BIM. In overseas, they are already using diverse softwares for reviewing modeling. Thus, For an automatic review of building regulations research is needed. this study is research on the development Domestic building codes as an automatic review process by using BIM. In order to Automatic review of the current building regulations by using BIM, this study analyzes the characteristics of each piece of information.

Building information modeling (BIM) is a smart construction technique that is recognized as essential for current construction facility projects. The Public Procurement Service (a construction project-ordering agency) announced a plan to introduce BIM and has required changing the operation of projects by using BIM design information. LCC analysis is essential for items, quantity, and cost information of the construction, and it is expected that efficient work will be achieved by using BIM design information. In this study, a BIM-LCC analysis system was established for selecting optimal design alternatives by actively using open KBIMS libraries. The BIM-LCC analysis system consists of a single alternative and an optimal alternative LCC analysis, but it has a limitation in that only the architecture and machine libraries have been applied. However, by applying BIM, practical use and work efficiency can be expected. In order to use the method as an LCC analysis support tool with BIM design information in the future, it will be necessary to collect user opinions and improve the UI.
