Critical Technologies for Efficiency and Competitive Advantage in Manufacturing: MES/MOM Systems and Their Role in IoT

In this article, we explore MES/MOM Systems and, in particular, the impact of IoT on industrial processes. We examine how these technologies come together and work collaboratively to improve manufacturing-facility efficiency and create a competitive advantage in the era of Industry 4.0 and digital transformation.

Modern industry must continually adopt new technologies to optimise manufacturing processes and improve efficiency. In this context, innovative technologies such as Manufacturing Execution Systems (MES), Manufacturing Operations Management (MOM) systems and the Internet of Things (IoT) are transforming industrial operations.

What Is MES?

MES is an abbreviation of “Manufacturing Execution System”. It is an information system used to manage, monitor and optimise manufacturing processes. MES plans, tracks, manages and reports the activities performed in production. It is used to improve manufacturing efficiency, assure quality, reduce costs and increase customer satisfaction.

What Is MOM?

MOM is an abbreviation of “Manufacturing Operations Management”. It is a management approach and system encompassing the planning, management, monitoring and optimisation of an organisation's manufacturing operations. MOM aims to improve efficiency, reduce waste and enhance product quality by ensuring that manufacturing processes are executed effectively.

The Relationship Between MES and MOM

MES and MOM are closely related because both are used to manage and optimise manufacturing operations.

MOM is generally considered broader in scope and covers every aspect of manufacturing processes. Activities such as production planning, scheduling, monitoring, quality management and inventory management fall within MOM.

MES forms a subset of these processes. More specifically, it covers operational activities such as real-time production-data monitoring, work-order management, and material and labour management. MES manages physical manufacturing activities and tracks them from the planning stage through execution.

MES is therefore generally regarded as part of MOM and is used to support processes within MOM's broader scope. It functions as a MOM component focused on the more specific aspects of manufacturing operations.

MES/MOM Systems and Their Role in IoT

MES and MOM systems are important in the context of IoT because the Internet of Things makes industrial processes more intelligent by enabling physical devices to communicate over connected networks. Important contributions of MES and MOM systems to IoT-enabled manufacturing include:

  • Data Collection and Analytics: IoT devices collect large volumes of data from manufacturing processes. MES and MOM systems gather and analyse this data and convert it into meaningful information, enabling manufacturing operations to be monitored and evaluated in real time.

  • Intelligent Decision-Making: MES and MOM systems use real-time manufacturing data to support intelligent decisions. If a production-line failure occurs, for example, the system can alert the relevant personnel automatically or generate alternative production plans.

  • Automation and Optimisation: MES and MOM systems enable manufacturing processes to be automated and optimised. By monitoring machine performance through IoT sensors, they can improve energy efficiency or reduce waste.

  • Remote Monitoring and Management: MES and MOM systems enable manufacturing facilities to be monitored and managed remotely. Operations can therefore be managed from any location, improving operational efficiency.
