Smart factory is a remarkable development from traditional manufacturing systems to data-based smart manufacturing systems that can connect and process data continuously, collected from machines, production equipment to production and business processes, capable of supporting workers in making decisions or performing work automatically. Smart factory is the key and center of the fourth industrial revolution, combining improvements in traditional manufacturing activities with digital technology to help factories achieve greater efficiency, contributing to increased revenue and reduce operating costs for businesses. Besides, the importance of smart factories is to make production more quality, efficient, competitive and sustainable. Businesses in Vietnam are in the process of learning and applying smart factory models. However, the number of businesses applying the pine factory model is still limited due to many barriers and difficulties. Therefore, in this paper we conduct a survey to assess the needs and current situation of businesses in applying smart factories and propose some specific solutions to develop and promote application of smart factory model in Vietnamese businesses.

Taylor and Ford in the 1910s led to the "scientific management" for the entire industry from the manufacturing spread of TQM Total Quality Management has been structured as a management efficiency, such as 6-Sigma techniques were developed. SW development also introduces the idea, such as CMMI and SPICE-based process management, management practices have evolved. However, in recent years to increase the knowledge of workers in the manufacturing process oriented management approach is under serious challenge. Business performance or productivity will be varied depending all motivation, human relationship, job involvement rather than simply putting a lot of time. Especially in the SW industry which is depending on human resource, Creativity should be limited in traditional management methods. Recently, Google and Apple, Cisco and global advanced companies adopt a human relationship management. Their productivity and creativity in product development has been successful by giving autonomy and motivation, enthusiasm and vision to tile employees. Human relationship management since the mid-1990s, appears as a new paradigm so called Agile process in the field of SW development. Agile processes emphasis on light, flexible and responding to changes immediately in the business environment step away from traditional management approach which is the heavy and complicated process. In this paper, agile project management concepts and practices which is applied to industry will be examined.

With research findings that the righteous and advanced society relies on the microscopic personal experience related to the justice as well as the perilous reality of 70% of corporate employees in all industrial environment, this study samples employees in the manufacturing and construction industry, both of which take up 40% of all industries, to look into how the awareness of the justice within their organizations influences the organizational commitment through psychological capital and occupational satisfaction; and to understand the beginnings for the macroscopic change. As a result of verifying the interrelationship between the justice and psychological factors, distributive justice and interactive justice are in a positive relationship with the psychological capital while procedural justice shows no influence; the procedural justice and interactive justice are positive with the occupational satisfaction whereas the distributive justice shows no influence. Also psychological capital appears positive with the occupational satisfaction and organizational commitment while occupational satisfaction is positively related to the organizational commitment.

경쟁적인 시장에서 살아남기 위해서는 공장의 공정제어를 정확하게 하는 것이 필수적이다. SPC(Statistical Process Control) 시스템은 품질 향상의 욕구를 충족시키기 위해 광범위하게 사용되어지고 있다. 하지만 대부분의 기존 상업제품들은 유연성이 떨어지고, 반자동적으로 운영되며, 다른 툴과의 접목에 어려움이 있다. 본 논문이 제안하는 rSPC(Real-Time SPC) 시스템은 웹을 기반으로 하고, XML을 입력/출력 프로토콜로 이용한다. 또한 강력한 그래픽 표현기능과 효율적인 파일 시스템으로 실시간 제어를 가능하게 한다. 새로운 SPC시스템은 어떤 생산체제에도 사용 가능하지만, 특히 반도체, TFT/LCD 산업에 최적화되어 있다. 시스템의 구현은 C++과 COM/DCOM을 사용하며, 기존의 제품보다 향상된 성능을 보인다.

Purpose - The study is to examine the impact of the US Purchasing Managers' Index (PMI) on Korea and the US industrial economy including the distribution industry. We analyze its effect on the industrial economy centered on the distribution industry using economy indices in Korea and the US. Research design, data, and methodology - The variables are used to analyze the dynamic relationship which occurs among the US PMI, the industrial production index, producer price index, unemployment rate, and manufacturing Inventories Index in Korea and the US from January 1990 to July 2016 using Vector Error Correction Model. Results - As a main result, the impact of the US PMI on all the economy indices both Korea and the US has the same cyclical movement. The US PMI is positively related to the producer price and the industrial production index of Korea and the US, while it is negatively related to unemployment rate, and the manufacturing inventories index in Korea and the US. Conclusions - The US PMI as an advanced index has a power to predict the economies on Korea and the US. In the end, we find that the US PMI has a great impact on Korea and the US industrial economy.

A well-established characterization method is required in powder bed fusion (PBF) metal additive manufacturing, where metal powder is used. The characterization methods from the traditional powder metallurgy process are still being used. However, it is necessary to develop advanced methods of property evaluation with the advances in additive manufacturing technology. In this article, the characterization methods of powders for metal PBF are reviewed, and the recent research trends are introduced. Standardization status and specifications for metal powder for the PBF process which published by the ISO, ASTM, and MPIF are also covered. The establishment of powder characterization methods are expected to contribute to the metal powder industry and the advancement of additive manufacturing technology through the creation of related databases.

로봇은 인간을 모방하여 외부환경을 인식하고 상황을 판단하며 자율적으로 동작하는 기계를 의미한다. 로봇은 제조용 로봇과 서비스용 로봇으로 구분하고 서비스용 로봇은 전문서비스용 로봇과 개인서비스용 로봇으로 분류된다. 최근 제조업의 생산성 경쟁 심화, 안전 이슈 부상, 저출산과 고령화 심화로 인해 로봇산업이 부상하고 있다. 최근 로봇산업은 첨단기술 분야의 복합체로 기술혁신성과 성장잠재력을 가지고 있기 때문에 각광받고 있는 산업분야이다. IT, BT 및 NT 관련 요소들이 융합되어 구현되는 기술로서 그 파급효과는 매우 커지고 있다. 사회구조와 생활패턴의 변화로 인해 생명 연장과 건강에 대한 사회적인 관심이 높아지고 있으며 의료관련 분야에 많은 관심이 모아지고 있다. 이제는 인공지능(AI) 산업이 급성장하고 있기 때문에 대 중소기업 협력 강화를 통한 글로벌 경쟁력을 확보하는 것이 우선 과제이다. 대기업의 장점인 R&D 투자능력과 마케팅 능력과 중소기업의 장점인 로봇 기술을 결합해야 하며 협력 모델 구축 및 M&A를 통해 글로벌 대기업과 경쟁력을 확보해야 한다.

The objective of this research is to select the most effective technique from AMT (Advanced Manufacturing Technologies) and IMP (Innovative Management Practices) for improving manufacturing performance in shipbuilding enterprises. The research consists of several principal steps. The first step is to design critical criteria in evaluating manufacturing performance in shipbuilding enterprises. The second step is to develop sub-criteria of the critical criteria. The third step is to develop a four level AHP (Analytic Hierarchy Process) structure using the critical criteria, sub-criteria and techniques from AMT and IMP. The fourth step is to develope the pairwise comparison matrix by each level of AHP structure, which was based on survey data collected at the H heavy industry. And the last step is to select the most effective technique from AMT and IMP by using AHP analysis. The results of AHP analysis did not show clear difference in priority between techniques of AMT and IMP in terms of manufacturing performance of the shipbuilding enterprise. Thus, each critical criterion was assigned modified weights and examined the priority change of techniques by conducting performance sensitivity analysis.
