A manufacturing company is only as good as its equipment. But more importantly, how well the organization uses its equipment. Without knowing the overall equipment effectiveness (OEE) of production machines, companies risk losing ground in a hyper-competitive manufacturing environment.
By capturing and analyzing OEE data, users can better understand how effectively their equipment is being used, which is incredibly important given the large capital expenditure that equipment represents.
An OEE dashboard can display not only the real-time OEE of a shop floor, but also identify trends, patterns, and paths for improvement, giving manufacturers a chance to improve efficiency as part of their continuous improvement initiatives.
An OEE Dashboard is a production reporting feature that displays real-time OEE scores for easily accessible consumption across the shop floor.
Visual OEE dashboards are populated with OEE scores based on shop floor data that has been collected, standardized, and contextualized.
MachineMetrics OEE dashboards allow end-users to track shift progress, identify areas of poor machine performance, and monitor machine conditions.
An OEE Dashboard from MachineMetrics shows equipment performance against pre-defined goals.
Overall Equipment Effectiveness (OEE) is defined as the amount of time a manufacturing machine is truly productive. It combines three distinct metrics - availability, performance, and quality - to achieve a score representing a machine's actual productive time. This helps operators, technicians, managers, and upper management make better decisions for optimized performance.
By displaying these conditions as an OEE dashboard, HMI, or remote terminal, end-users can analyze various factors such as shift or machine type. They can also look at operational efficiency across many machines, analyze effectiveness between operators, or look at the entire factory at a meta-level.
These digital manufacturing dashboards allow contextualized human-centric data to be added at the point of use. In addition, they can be used with other analytics dashboards to review data side by side for informed decision-making, whether you are on the shop floor or back office.
OEE dashboards are required to eliminate the risk of human error and time delays, ensuring that equipment is being utilized to meet production goals. To capture OEE more effectively, machine data platforms like MachineMetrics capture data directly from the control of the machine. This ensures that the production data is real-time, accurate, and standardized across all makes and models of equipment.
With data collected and contextualized, it can be displayed on intuitive OEE dashboards to enable a real-time look at performance. This ensures complete visibility of the shop floor for operators, managers, and executives.
By allowing users to quickly review factors such as downtime, production, and other variables, insights affecting quality and efficiency can be consumed at the point of use. And action can be taken immediately to resolve issues or prevent them altogether.
Here are several areas where an OEE dashboard is required:
An OEE dashboard allows companies to track OEE over time. Human activity in machine operation can impact quality, downtime, and operational efficiency. Using OEE dashboards and reports to track performance over time means that managers can look at different levels of OEE by the hour, shift, day, week, or any other time frame desired.
A MachineMetrics OEE Report displaying key metrics as well as historical OEE performance.
Low OEE on any of these periods can help managers understand downtime reasons, better direct maintenance departments, and optimize manufacturing processes to significantly improve their OEE. Because production is enormously complicated in any manufacturing company, the capability to monitor OEE graphically or through an OEE report can make a big difference in improving performance.
Robust machine data platforms like MachineMetrics allow OEE dashboards to be used alongside other dashboards to transform insights such as performance, parts goals, and other critical metrics. The insights delivered are more accurate than human-centric metrics.
This functionality is built into the dashboard view and enhances users' decision-making. Users can quickly select between OEE and other dashboards quickly. They can also zoom in to a detailed view or out to a high-level view of machine groupings or the entire factory.
This can be helpful for identifying areas of opportunity, such as under-utilized equipment, excessive downtime, or bottlenecks in production processes.
Machine performance can be color-coded on all metrics to keep operators up to date on progress toward established goals. This can help encourage healthy operator competition. Simple color schemes of green, orange, and red allow further visual cues and display OEE data in real-time.
The days of running manual time studies are long gone. When data is acquired in real-time, the need to manually capture run time, changeover time, and other information is eliminated.
Human-centric data is also error-prone, so even if the time is captured, the reason may be misunderstood or biased based on the perception of the recorder. By capturing data using sensors and devices, the need for human input is significantly reduced except in cases where it can be added to the automated data capture in the form of contextualization.
This process drives the best use application where some human-added data is optimally captured for context issues while leaving the absolute data capture to embedded sensors and devices.
OEE can be used effectively as a benchmark for measuring progress. OEE score is calculated by multiplying its three elements:
OEE score is calculated by multiplying three elements together, Availability, Performance, and Quality. The calculation for the individual elements are:
The simple calculation for OEE is:
Or combining the calculations of the three elements:
There are several dos and don'ts associated with OEE dashboards.
MachineMetrics is a robust, best-in-class system for collecting, standardizing, and taking action on production data. Out-of-the-box reports and dashboards, such as real-time OEE dashboards. These dashboards are accessible at each machine, above the shop floor, and in back offices.
Using the OEE dashboards from MachineMetrics, operators, technicians, and managers have access to customizable and configurable data that optimizes and streamlines operations. This real-time information is analyzed to gather insights that can be immediately used to take action.
The system is flexible, allowing C suite execs and factory floor operators access to the same information simultaneously. This means companies can use these dashboards to make both tactical and strategic decisions, with everyone operating with a single version of the truth.
