Abstract

Currently, the amount of containers is growing up continuously. However, they still depend on humans checking or validating. In this situation, humans must participate in the systems. Situation-awareness technologies allow human participation to be minimized. The situation-awareness technologies provide data or service appropriate to the object's current state, and the state is recognized automatically by the system. They can automatically execute working processes without human intervention. We suggest a middleware system based on situation-awareness technologies using an ontology for the safety transportation of containers. The middleware is aware of the current state and sends the data required by an application. It can help build new applications by enhancing agility, and it can also support automated service processing by invoking the service required like fire-fighting, fixing container, and so on. Improving transportation of containers process automation with situation-awareness technologies reduces manpower requirements for checking and validating containers, and so saves logistics costs of container transportation.

현재 컨테이너 물동량은 지속적으로 증가하고 있는 추세이며 이에 따라 수송 원가를 절감하기 위해 초대형 컨테이너선들이 늘어나서 컨테이너 운송이 대형화되어지고 있다. 그러나 항만의 자원은 한정되어 있어서 효율적이고 안전하게 운송하기 위해서는 컨테이너에서 수집된 센서 데이터를 기반으로 환경과 상황에 따른 정보들을 활용하여 지능적이고 적응적인 서비스를 제공하는 방법이 필요하게 되었다. 본 논문에서는 이러한 문제를 해결하기 위해서 상황인식 기법을 적용한 컨테이너 상황인식 미들웨어를 제시하였다. 먼저 사용자, 사물과 동작, 서비스를 포함하는 모든 것을 통칭 적으로 컨텍스트라는 범주로 포함시키고 이 정보를 바탕으로 서비스의 제공이 필요한 상황마다 활용하기 위해서는 컨테이너 도메인의 상황적 요소를 분석해서 컨테이너가 처할 수 있는 특정 상황들이 어떠한 요소들의 조합으로 이루어지는지 정의하고 그 요소들 사이에는 어떤 관계성이 있는지에 대한 컨테이너 상황 온톨로지 모델링을 하였다. 온톨로지 모델을 바탕으로 컨테이너 및 환경에 대한 컨텍스트를 온톨로지로 구축하고 추론을 위한 규칙을 기반으로 상황인식적인 서비스를 추론하는 미들웨어의 개발 및 우선순위 등 정책적인 상황 관리를 가능하게 하는 기능을 구현하였다.
