Summary of OnTop easyMES – Technical Merit, Innovation and Relevance for Flexible Manufacturing

easyMES, developed by OnTop Automation AB, is a cloud-based Manufacturing Execution System (MES) designed for the Swedish manufacturing and assembly industry. The system represents a departure from traditional MES and ERP solutions by being built as an adaptive service platform, where functionality is activated progressively according to business needs rather than installed as fixed software modules. The platform integrates IoT, real-time production management, OEE monitoring, APS planning and scheduling, and ERP integration within a unified SaaS architecture running on Microsoft Azure.

Technical Merit and Innovation

The primary technical merit of the development lies in the combination of several technological and operational innovations:

• Service-Based MES Architecture enabling companies to start with a single function, such as automatic IoT data collection, and gradually expand the system with additional MES services without requiring system replacement or restructuring. This differs significantly from traditional module-based MES systems.

• Automated IoT Integration that allows machines, robots, collaborative robots (cobots), and manual assembly processes to be connected for real-time data acquisition without extensive local IT infrastructure or specialized technical expertise.
• Real-Time Operational Management where production status, downtime, OEE, cycle-time deviations, and resource utilization are continuously visualized through adaptive dashboards accessible via web browsers and mobile devices.
• Real-Time Data-Driven APS Planning and Scheduling that enables customer-order-driven and consumption-driven planning in pull-based production environments. Production plans are dynamically updated based on actual shop-floor performance rather than static planning assumptions.
• Seamless ERP Integration via APIs, allowing manufacturers to retain existing ERP systems while adding advanced MES functionality without costly ERP replacement projects.

Relevance for Swedish Industry

• Swedish manufacturing companies are increasingly characterized by high product variation, shorter production runs, growing demands for delivery precision, and shortages of skilled labor. Addressing these challenges requires production systems capable of adapting rapidly to changing customer requirements. easyMES addresses these needs by:
  • providing real-time visibility into production operations,
  • reducing dependence on manual reporting,
  • improving resource utilization,
  • enabling rapid rescheduling in response to disruptions,
  • supporting Lean Production and continuous improvement initiatives,
  • increasing delivery reliability and productivity through data-driven decision-making.
• Particularly relevant is the platform's ability to support both highly automated production lines and manual assembly operations within the same system environment, reflecting the operational reality of many small and medium-sized manufacturing companies in Sweden.

Overall Assessment

easyMES represents a modernization of the traditional MES concept by combining cloud technology, IoT connectivity, real-time production control, and adaptive service deployment within a single platform. The innovation lies not only in the individual technologies employed, but also in the way they are integrated into a scalable and incrementally expandable system that makes advanced digital production management accessible to small and medium-sized manufacturers.

The result is a flexible manufacturing platform that strengthens the competitiveness of Swedish industry through higher productivity, improved resource utilization, faster adaptation to market changes, and enhanced delivery performance.
