How to Calculate OEE in Plex

Overall Equipment Effectiveness (OEE) is a critical performance metric used in manufacturing to measure the efficiency and productivity of equipment. It provides insights into the utilization of resources, identifies areas of improvement, and ultimately helps optimize production processes. If you are using Plex, a cloud-based ERP system, calculating OEE becomes even more efficient and integrated.

Understanding Overall Equipment Effectiveness (OEE)

OEE is a crucial metric in manufacturing industries that provides a comprehensive insight into the efficiency of equipment. It is a combination of three fundamental factors: Availability, Performance, and Quality. Availability refers to the percentage of time that the equipment is actually available for production compared to the total planned production time. This factor takes into account factors such as downtime for maintenance, changeovers, and unexpected breakdowns.

Performance, another component of OEE, evaluates how well the equipment is performing in terms of speed and efficiency. It considers factors such as cycle time, machine speed, and any idling time during production runs. By analyzing the Performance factor, manufacturers can identify opportunities for optimization and improvement in their processes.

Quality, the third element of OEE, focuses on the quality of the output produced by the equipment. It measures the number of defects, errors, or rework needed in the units manufactured. Monitoring the Quality factor helps in ensuring that the products meet the required standards and specifications, ultimately impacting customer satisfaction and overall production efficiency.

Configuring Plex for OEE Calculation

To accurately calculate OEE in Plex, proper configuration is essential. Firstly, ensure that your equipment is defined accurately in the system, including specifying its capabilities, production rate, and planned downtime. This step is crucial as it forms the foundation for OEE calculations, ensuring that the system has a clear understanding of the equipment’s operational parameters. Detailed equipment definitions also enable Plex to provide insights into potential performance improvements and maintenance schedules.

Secondly, establish the necessary data collection points within the system by integrating with machine sensors or manual inputs. These data points should capture relevant production metrics, such as cycle times, downtime reasons, and defect counts. By collecting comprehensive data, Plex can offer a holistic view of production efficiency and identify areas for optimization. Additionally, real-time data collection enables immediate visibility into production performance, allowing for quick decision-making and proactive maintenance strategies.

Once the equipment and data collection are properly configured, Plex can automatically calculate OEE based on the collected data.
