Purpose This study investigates the impact of organizational characteristics on organizational performance through case studies of smart factory implementation in the context of Korean small and medium Enterprises (SMEs). To achieve this goal, this study adopts the smart factory index of KOSMO (Korea Smart Manufacturing Office) established by Korean Ministry of SMEs and Startups. We visited 3 firms implemented smart factory projects. This study presents the results of field study in detail with evaluation criteria on how organizational competences like AI technology adoption and facility automation can be exploited to positively influence organizational performance through smart factory implementation. Design/methodology/approach There are not so many results of empirical studies related to smart factories in Korea. This is because organizational support and user involvement are required for facility AI platform service beyond factory automation after the start of the 4th Industrial Revolution. Korean government's KOSMO (Korean Smart Manufacturing Office) has developed and proposed a level measurement index for smart factory implementation. This study conducts case studies based on the level measurement method proposed by KOSMO in the process of conducting case studies of three companies belonging to the root and mechanic industries in Korea. Findings The findings indicate that organizational competences, such as facility AI platform adoption and user involvement, are antecedents to influence smart factory implementation, while smart factory implementation has significant relationship with organizational performance. This study provides a better understanding of the connection between organizational competences and organizational performance through smart factory case studies. This study suggests that SMEs should focus on enhancing their organizational competences for improving organizational performance through implementing smart factory projects.

디스플레이 분야에 스마트 팩토리란 작업 자동화 뿐만 아니라 기존의 공정관리, 이동설비, 공정이상, 결함 분류 등에 AI/BIG DATA 기술을 이용한 보다 효율적인 디스플레이 제조를 의미한다. 과거 디스플레이 제조 과정에서 불량이 나오면 결함 분류, 공정 이상에 대한 대처가 시시각각 달랐기 때문에 이에 대한 많은 시간 소모가 발생했었다. 하지만 디스플레이 제조 분야는 고도화된 공정 장비를 이용해야 하고 불량 원인을 신속하게 파악해 수율을 올리는 것이 디스플레이 제조 산업의 경쟁력이다. 본 논문에는 스마트 팩토리 AI/BIG DATA 기술을 디스플레이 제조에 접목한 사례들에 대해 정리해 보고 기존 방법 대비 어떤 장점이 도출 되어질 수 있는지에 대해 처음으로 분석해 보고자 한다. 이를 통해 향후 AI/BIG DATA를 이용한 디스플레이 제조 분야에 보다 향상된 스마트 팩토리 개발을 위한 사전지식으로 활용하고자 한다.

A smart factory is defined as a cutting-edge, intelligent factory that integrates all production processes from product planning to sales with information and communication technology. Through these factories, each company produces customized products with minimal cost and time. The smart factory promotion project in Korea has produced positive results even in difficult environments such as the COVID-19 situation. Through the transition to a smart manufacturing production system, the competitiveness of small and medium-sized businesses has been greatly strengthened, including increased productivity and reduced costs. This study was based on surveyed data conducted by organizations related to smart factory promotion in 2020. Significant contents and major characteristics that emerged from the surveyed data were inferred and described. Since the meaningful contents reflect the reality of the company, more efficient promotion of smart factories will be possible in the future.

본 논문에서는 AI 엣지 디바이스를 이용한 스마트 팩토리 위험도 개선시스템 및 위험도 개선방법을 설계한다. 스마트 팩토리 위험도 개선시스템은 AI 엣지 디바이스를 이용하여 스마트 팩토리에서 작업자의 작업수행 과정을 수집, 분석, 예방 및 신속 대처하고, 작업자의 작업 수행시 불량률을 개선하면서 작업시 발생 가능한 위험을 저감할 수 있다. 특히 작업자 이미지 정보, 작업자 생체정보, 장비 구동 정보 및 제조된 제품의 품질정보에 기초하여 위험도 이상 조건을 설정할 수 있고, 효율적이고 정확도 높은 작업이 되도록 위험도 개선이 가능하다. 또한 스마트 팩토리 내부의 카메라 및 IoT 센서 등에서 수집된 데이터는 모두 클라우드로 보내지 않고 AI 엣지 디바이스에서 처리하고, 필요한 데이터만 클라우드 등으로 전송할 수 있으므로 처리 속도가 빠르고, 보안에 관한 문제가 적다는 장점이 있다. 추가적으로 AI 엣지 디바이스를 사용함으로써 클라우드로 데이터 전송량이 감소하여 데이터 통신비 및 데이터 전송 대역폭을 확보하는 비용이 절감되는 장점이 있다.

We propose the AI Smart Factory Model for integrated management of production processes in this paper .It is an integrated platform system for the production of food packaging containers, consisting of a platform system for the main producer, one or more production partner platform systems, and one or more raw material partner platform systems while each subsystem of the three systems consists of an integrated storage server platform that can be expanded infinitely with flexible systems that can extend client PCs and main servers according to size and integrated management of overall raw materials and production-related information. The hardware collects production site information in real time by using various equipment such as PLCs, on-site PCs, barcode printers, and wireless APs at the production site. MES and e-SCM data are stored in the cloud database server to ensure security and high availability of data, and accumulated as big data. It was built based on the project focused on dissemination and diffusion of the smart factory construction, advancement, and easy maintenance system promoted by the Ministry of SMEs and Startups to enhance the competitiveness of small and medium-sized enterprises (SMEs) manufacturing sites while we plan to propose this model in the paper to state funding projects for SMEs.

A new paradigm based on distributed manufacturing services is emerging. This paradigm shift can be realized by smart functions and smart technologies such as Cyber Physical System (CPS), Artificial Intelligence (AI), and Cloud Computing. Most architectures define stack levels from Level 0 (equipment) to Level 4 (business area) and specify the services to be provided between them. Because of their a rough technical specification, there is a limitation on how to actually utilize a technology to actually implement a smart factory service with this architecture. In this paper, we propose a smart factory architecture that can be utilized directly from the perspective of a smart service system by making the use of System Engineering Process and System Modeling Language (SysML).

작업자-로봇 간 협업은 다품종 소량생산 기반의 스마트팩토리에서 중요한 요소가 된다. 기존 제조 공장을 스마트화하기 위해 AI 기반의 기술이 도입되고 있지만 이 경우 단기적 생산성 향상에 그친다. 이를 해결하기 위한 협업 지성은 인간의 팀워크, 창의력 등과 AI의 속도, 정확성 등이 결합되어 서로의 단점을 적극적으로 보완 할 수 있다. 그러나 현재 자동화설비는 돌발사태 발생 시 재해강도가 높기 때문에 안전대책이 요구된다. 따라서 본 논문에서는 깊이 영상 카메라를 이용하여 작업자 및 설비를 가상 세계에 구현하고, 시뮬레이션을 통해 작업자의 안전을 판별하는 공장 안전 제어 시스템을 설계하고 구현한다.

Smart factories can be defined as intelligent factories that produce products through IoT-based data. In order to build and operate a smart factory, various new technologies such as CPS, IoT, Big Data, and AI are to be introduced and utilized, while the implementation of a MES system that accurately and quickly collects equipment data and production performance is as important as those new technologies. First of all, it is very essential to build a smart factory appropriate to the current status of the company. In this study, what are the essential prerequisite factors for successfully implementing a smart factory was investigated. A case study has been carried out to illustrate the effect of implementing ERP and MES, and to examine the extensibilities into a smart factory. ERP and MES as an integrated manufacturing information system do not imply a smart factory, however, it has been confirmed that ERP and MES are necessary conditions among many factors for developing into a smart factory. Therefore, the stepwise implementation of intelligent MES through the expansion of MES function was suggested. An intelligent MES that is capable of making various decisions has been investigated as a prototyping system by applying data mining techniques and big data analysis. In the end, in order for small and medium enterprises to implement a low-cost, high-efficiency smart factory, the level and goal of the smart factory must be clearly defined, and the transition to ERP and MES-based intelligent factories could be a potential alternative.
