Major countries are trying to expand the construction of smart factories by introducing ICT such as the Internet of Things, cloud, and big data into the manufacturing sector to secure national-level manufacturing competitiveness in the era of the 4th industrial revolution. In addition, Germany is pushing for Industry 4.0 to build a fully automatic production system through the Internet of Things, and China is pushing for the expansion of smart factories to enhance the country's industrial competitiveness through Made in China 2025, Japan's intelligent manufacturing system, and the Korean government's manufacturing innovation 3.0. In this study, considering the increasing security connectivity of smart factories, we would like to identify security threats in the external connection part of smart factories and suggest security enhancement measures based on domestic and international standard security models to respond to the identified security threats. Eventually the proposed method can be applied by accurately identifying the smart factory security status, diagnosing vulnerabilities, establishing appropriate improvement plans, and expanding security strategies to respond to security threats.

The construction of smart factories for government SMEs is not easy due to the lack of professional manpower. The use of retired professionals is a way to solve the problem to some extent and to solve the job problem of seniors by effectively utilizing social assets. This study examines the effectiveness of using Meister based on a survey of 195 companies participating in the Smart Meister Support Program. As a result, the better pre-participation readiness and the better management and coordination of change during the participation, the more significant influence was on Meister's ability development and corporate performance. In particular, it was confirmed that Meister's competence plays a role in both 'pre-participation readiness and business performance' and 'between change management during participation and business performance'. In order to improve the performance of the smart meister business in the future, it is necessary to proactively promote the purpose and purpose of the business targeting companies that wish to participate in the business. In addition, it was found that it is necessary to support the development of change management in order to minimize the resistance to innovation during the project. It will be possible to enhance social competitiveness by resolving senior jobs and strengthening the competitiveness of SMEs by discovering and utilizing Meister, who is an expert among retirees.

최근 4차 산업혁명에 대한 관심이 증가하고 있다. 그 중 제조업 분야에서는 사이버 물리 시스템(CPS) 기술을 기반으로 제조의 모든 단계를 자동화, 지능화 시킨 스마트팩토리 도입이 확산되고 있는 추세이다. 스마트팩토리는 그 복잡도(Complexity)와 불확실성(Uncertainty)이 크기 때문에 예상치 못한 문제가 발생할 가능성이 높고 이는 제조 공정 중단이나 오작동, 기업의 중요 정보 유출로 이어질 수 있다. 스마트팩토리에 대한 위협을 분석하여 체계적인 관리를 수행할 필요성이 강조되고 있지만 아직 국내에서는 연구가 부족한 상황이다. 따라서 본 논문에서는 스마트팩토리의 전반적인 생산 공정 절차를 대상으로 Data Flow Diagram, STRIDE 위협 모델링 기법을 이용하여 체계적으로 위협을 식별한다. 그리고 Attack Tree를 이용해 위험을 분석하고 최종적으로 체크리스트를 도출한다. 도출된 체크리스트는 향후 스마트팩토리의 안전성 검사 및 보안 가이드라인 제작에 활용 가능한 정량적 데이터를 제시한다.

The computerized automation of modern manufacturing system is tremendously important for the cost reduction. Recently, the automation is being realized by Computer Integrated Manufacturing (CIM) concept and the unmanned factory is the final goal of the automation. The automation of the low level of factory is the most crucial and difficult aspect in total CIM environment since various machines are involved. A cell is defined as a manufacturing group of closely related machineries in the entire factory hierarchy, The management scheme for a cell controller is defined from the software viewpoint. The domain of a cell is designed with tasks(processes) in a multiple-task operating system. The operation of the cell is established by defining schemes for overall control of the cell domain, databases, job scheduling, communications within the domain, user-interface and communications with outside machines. Although the software is developed in a specific operating system and WINDOW facilities, the operating strategies can be applied globally.

Virtual Manufacturing is a technology to facilitate effective product development and agile production by computer models representing the physical and logical schema and the behavior of real manufacturing systems including manufacturing resources, environments and products. For the successful application of this technology, a virtual factory as a well-designed and integrated environment is essential. In this research, we constructed a sophisticated virtual factory model of an automotive company's paint shop, and performed precise simulations of unit cells, lines and whole plant operations for collision check and off-line programming. It is expected that this virtual paint shop is useful for achieving time and cost savings in many manufacturing preparation and planning activities of new car development processes.

To ensure competitiveness in the modern automotive market, material arrangements and information managements should be performed concurrently with new car developments. In automotive general assembly shops, thus, new business workflow and supporting environments are inevitable to reduce the manufacturing preparation time in developing a new car in the manner of concurrent and collaborative engineering. Since complete material arrangements for a whole general assembly system is a huge and complex job, several planners should execute their planning jobs and share information. Therefore, each planner should provide others with his/her results with continuous on-line communication and cooperation. Digital automotive general assembly factory is useful the performing concurrent and collaborative engineering and is essential for material arrangements and information managements systems. In this research, we constructed a sophisticated digital factory of an automotive general assembly shop by measuring and modeling through the parametric 3-D CAD, and a web-based system for concurrent and collaborative material arrangements for automotive general assembly via 3D mock-up is developed. By the digital general assembly shop and developed web-based system, savings in time and colt of manufacturing preparation activities are possible, and the reliability of the planning result Is greatly improved.

Generally, over 95% of manufacturing cost is determined in the design and manufacturing preparation step, especially a great part of productivity is determined in the manufacturing preparation step. In order to improve the manufacturing competitiveness, we have to verify the problems that can be occurred in the production step and remove the unnecessary factors in the manufacturing preparation step. Thus, manufacturing industries are adopting digital manufacturing system based on modeling & simulation. In this paper, we introduce e-FEED system (electronic based Front End Engineering and Design) that is the integrated design and analysis system for optimized manufacturing line development based on simulation automation and explain the work process (Design, Analysis and Optimization) about manufacturing line development using e-FEED system. Also, the effect is described through the real implementation cases.

최근 공개 표준과 통합 네트워크에 대한 요구가 증가하며, 하위 제어 계층에서도 이더넷 네트워크를 기반으로 한 시스템의 도입이 증가하고 있다. TCP/IP 기반의 네트워크를 상위 계층에서 하위 제어 계층까지 사용하는 방식으로 확장함으로써 공장 자동화용 애플리케이션을 이더넷 상에서 구현, 상위 관리 프로그램 및 DB 시스템과 직접 연동되는 통합 망 개념의 공장 자동화 시스템을 완성할 수 있게 된다. 본 논문에서 구현된 시스템은 공장 자동화 전용 이더넷 제어 시스템의 국제 표준인 Ethernet/IP 표준 시스템을 기반으로 하는 제어용 통신 디바이스를 구현하는 것을 목표로 하였다. 본 논문에서 구현된 시스템은 CIP의 표준 인터페이스에 기반한 네트워킹 기능을 수행하며, 이더넷 네트워크 환경이 다른 제어 시스템의 규격에 비하여 큰 대역폭을 갖고 있는 시스템이므로 네트워크의 데이터 전송 특성을 상당히 개선됨을 실험을 통하여 확인하였다.
