Development and Application of MES Based on Cloud Platform for Steel Structure Enterprises In recent years, manufacturing execution system (MES) has been widely used in the manufacturing industry. MES plays an important role in supporting enterprise workshop management. However, generalized MES cannot be applied well in steel structure enterprises due to the particularity and complexity of steel structure enterprises. This paper takes into account the production characteristics and needs of steel structure enterprises and an MES structure based on cyberphysical system (CPS) is proposed. This architecture includes the physical layer, the network layer and the application layer. The cloud platformbased MES system was applied to a steel structure enterprise in Changchun, China, and the functions of each module were introduced in detail. The MES can effectively improve the informatization level of the enterprise, creating a transparent, informative and intelligent production environment for steel structure enterprises. The developed MES can improve resource utilization, reduce enterprise costs, improve product quality, and lay the foundation for steel structure enterprises to found intelligent factories.

Approach for Implementing Industry 4.0 Framework in the Steel Industry The advancements of the Steel Industry require a fully integrated manufacturing and business system for realtime decision making. The main challenge in the Steel Industry is the disconnection between the shop floor systems such as Manufacturing Execution System (MES) and business systems such as Enterprise Resource Planning (ERP). The production process of Steel Industries requires visibility of operations, planning and scheduling, lead times, quality management, machine health, maintenance planning, to name but a few aspects. This study investigates current technologies and investments employed by steel companies and how to leverage these existing investments to attain a smart enterprise and subsequently manage current and future steel demands efficiently. Industry 4.0 simplifies the approach to implement complex systems in a structured and logical manner in manufacturing organisations. This paper deliberates the Industry 4.0 framework and the path to implement Industry 4.0 in the steel sector.
