Based on reviewing the literature and statistical year books on current projects that are targeting Industry 4.0 and Smart Factory, this paper aims to show concepts of Industry 4.0, and Smart Factory. Also it shows 5 projects for Industry 4.0 led by governments that worry over their low employment and productivity in main industrialized countries: Germany, China, Japan, the USA, and Korea. In addition it presents some problems which are very important but easy to be overlooked, especially on employment, and it makes three suggestions to solve employment problems. First, government should tax the profit which a company makes on reducing workers in spite of a high rate of profit through technology innovation. Second, to help small businesses to last longer, government should link major companies and small companies. Third, government, academic circles and the industrial world should take part in configuring consortia like American "Industry talent Consortium" to cultivate IT Talent.

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.

Smart factories represent the Fourth Industrial Revolution and related emerging technologies across all industries. Among those emerging technologies, digital twin (DTw) enables smart manufacturing, resembling the factory's physical components and functional services. Nevertheless, from the owner-operator perspective, there has been only a paucity of studies defining the functional services of 'facility' and 'equipment' for the smart factory. This fact has also encouraged the construction industry to expand its role into factory operations by supporting digitalized production equipment and facilities. In order to address this issue, this study uses the proposed list of three-level facility asset management (FAM) breakdown structure by Jin et al. [12] that is under review for possible publication. The FAM breakdown structure is then validated with function lists from previous studies and existing ISO standards. It selectively covers the areas of traditional construction management (CM), asset management (AM), facility management (FM), and production operation management (OM). A mapping table with practical information systems used in the four areas (CM, AM, FM, OM) is also analyzed to verify the proposed FAM breakdown structure. It is expected that the result of this study can be used as a standard function to develop a smart factory FAM digital twin for researchers and practitioners.

This study confirms the impact relationship between the president and employee competency related to smart factory construction of manufacturing SMEs, the acceptance intention and management performance in smart factory construction. The 310 data collected through a questionnaire were tested for research hypotheses through SEM. As a result, the president and employee competency affects the smart factory acceptance intention and the employee competency affects the management performance. Acceptance intention has a positive impact on management performance. Regional characteristics have a moderating effect on the relationship between president competency, acceptance intention, and management performance. Through this study, it was confirmed that the president and employee competency was an important factor in smart factory built.

This study proposes a CMS platform for AR-based remote collaboration in a smart factory. The Smart Factory site utilizes various forms of AR technology to save time and money. As the level of smart factory increases, system-oriented tasks such as machinery and equipment are performed in people-oriented work. Therefore, there is a need for a system that allows the operator to immediately repair the machine or equipment in case of a failure, or to get help if necessary. Remote collaborative CMS platform is designed to work in conjunction with DATABASE of ERP, MES / POP, and PLM system built through text, 2D 3D contents and smart factory business, This study is meaningful in that it saves time and cost by sharing information such as management, repair method, manual, etc., and repairing it quickly.

Recently, world leading companies on manufacturing field are trying to adopt a PLM methodology, which is a new production paradigm, for a survival and strengthening the competitiveness. Some projects for a digital shipyard including a methodology of a digital simulation framework are going on by Seoul national university and Samsung heavy industry. A Database methodology for a scheduling data, an interfacing methodology for a simulation input and output, and a synchronized simulation related methodology are required for enhancing the value of the digital simulation for shipbuilding. In this paper, such a methodologies and a related case study for a fabrication factory and an assembly factory are presented.
