These days, international air-logistics demand is getting bigger and bigger by increasing in trading volumes of export and import of Asia. It makes the air logistics of stakeholder to invest in air logistics facilities and information systems for meeting the growth of air transportation. However there are some problems that the efficiency of investment is not good by duplicately investing in information systems and moreover not compatible with each other because the stakeholder is investing in individual information system and air logistics facilities instead of constructing the integrated infrastructure. In this paper, we investigated the export, import, and transshipment process of air logistics to simplify air logistics process through the RFID(Radio Frequency Identification) application and the 4PL system.

The portion of air logistics is getting growing in the global logistics and customer need the rapidity and accuracy for freight delivery. But, the process of air logistics is so complicated because there are too many stakeholders involved in the process. So we suggest the way to make simple the process for improving ability of handling air freights. First, we analyze the AS-IS process and problems by studying previous documents and researching the field. Also we offer how to adopt the ways that are solutions concerning AS-IS process. Second, we suggest integrated information system that will make it simple the air logistics process and mitigate the intensive work load of air cargo. Also we show the reliance about our suggestion by simulation comparing TO-BE process to AS-IS process. We result in that this study will contribute to improve air logistics process by making simple the process.

Air logistics is getting growing continuously because customers need to increase rapidity and accuracy, but it isn't enough to study the process about air logistics in South Korea. We analyze the AS-IS process and problems by studying previous documents and researching in this field. We offer how to adopt the ways that are solutions concerning AS-IS process and benchmarking e-freight of IATA. Our suggestion reduces stakehoders' work load by using integrated system. We believe it will contribute to improve air logistics process by making simple the process.

21세기 국제항공운송 수요는 아시아의 급속한 수출입 화물량의 증가에 힘입어 지속적으로 증가하고 있으며, 항공물류 이해관계자들은 이러한 항공화물의 수요를 충족시키기 위해 시설 및 정보시스템 등에 대한 투자를 확대하고 있다. 하지만 항공물류 프로세스 전반에 걸친 시설 및 정보 시스템의 투자가 아닌 항공물류 주체별 개별 투자로 인해 동일한 목적을 지닌 시스템이 중복되게 사용되고 있으며, 상호 호환성에도 문제가 존재한다. 본 연구에서는 항공물류 프로세스 전반을 분석하고, 전술한바와 같은 물류 주체간개별 시스템의 호환성을 제고하기 위하여 RFID(Radio Frequency IDentification)기술을 도입한 항공물류 통합시스템을 제안함으로써, 항공물류 프로세스의 간소화 방안을 모색하고자 한다.

The air logistics process is complex and needs many informations because various agencies participate in the logistics service and many stakeholders in air logistics. But it is hard to improve the infra of facilities because of an enormous expense, so air logistics process has to simplify for growing air freight. Nevertheless some documents are same, they should be changed due to different format. Also documents have to change even though different documents have same informations. Consequently, errors are increased because the names of the same data are different from each other and stakeholders have to reproduce the documents. In order to mitigate these problems, we selected documents and analyzed document data for the interface optimization in general air logistics process. Next, we unified the data names and defined contents of data. Also we set the type of the defined data on DB type, and gave the code to the defined data. It made easy to exchange informations among the stakeholders to match documents corresponding with the defined data. Finally, the simulation of air logistics processes was performed the quantitative analysis of the data that occur in the air logistics. In conclusion, we expect to reduce the inefficiency such as reproduction of data and the errors by improving the interface of information.

The air logistics process is complex and need many informations because various agencies participate in the logistics service and there are many stakeholders in air logistics. But it is hard to improve the infra of facilities because of an enormous expense, so it needs to simplify air logistics process for growing air freight. When documents are sent, it needs to change the form of documents in spite of same document due to different form by agencies. Also documents are changed even though different documents have same informations. Consequently, errors are increased because the names of the same data are different from each other and stakeholders reproduce the documents. In order to mitigate these problems, we selected documents and analyzed data of documents for the interface optimization in general air logistics process. Next, we unified the names of data and defined contents of data. Also we set the type of the defined data on DB type, and gave the code to the defined data. It made easy to exchange informations among the stakeholders to match documents corresponding with the defined data.

항공물류 분야의 개선을 위해 공항에서 연구와 투자를 통하여 공항 선진화를 이루고 있고, 우리나라도 지속적으로 증가하는 항공물류 분야의 개선이 필요하다고 인식하고 개선을 위한 방안을 연구하고 있지만, 항공물류 전반에 걸쳐 통합적인 개선이 이루어지지 않고 개별적이거나 부분적인 시스템 개선으로 중복 투자와 비효율성의 문제가 발생하고 있다. 본 논문에서는 이러한 문제점들을 해결하기 위해 현행 항공물류 프로세스를 수 출입으로 구분하여 분석하였고, 시스템 통합 사례들을 검토하여 프로세스 상에서 발생하는 문서들을 분석하였다. 이중 인터페이스 대상 문서를 선정하고 문서의 데이터 내용과 형식을 정의하였다. 정의한 데이터의 형식을 대상 문서에 코드로 적용시키고 시뮬레이션을 통하여 데이터 저장량을 비교 분석하였다. 이를 통해 항공물류 이해관계자간의 정보 교환이 용이해지고 동일한 정보를 재생성하거나 재가공하는 비효율성을 감소시킬 것으로 기대된다.

Geofence defines the area that UAS should not enter or exit to ensure the safety of their operations, and is considered as one of critical capabilities of the UTM (UAS traffic management) system. In this study, a geofence simplification method using modified perpendicular algorithm is proposed. The performances of the proposed geofence simplification method were evaluated with actual building data, and the evaluation results confirmed that the number of vertices can be effectively reduced while minimizing the spatial size of the geofence.
