Improving manufacturing OEE in the food & beverage sector.
Measuring OEE accurately, consistently and at any given moment can be incredibly difficult for manufacturers.
What’s more, getting entire teams to embrace new methodologies and tools is not easy, so it needs simple and friendly interfaces and careful planning to drive change on the factory floor – which is where Rayven’s Manufacturing OEE IoT solution can help.
Understand your OEE in real-time with OEE Dynamix
Defining what data to collect is critical
In order to create a solution that can provide the insights needed to increase OEE, we started by identifying the key metrics required to measure them. In this solution it included:
- Hourly and daily targets
- Machine status
- Shift schedules
- Real-time throughput
- Downtime reasons
- Production schedule
Initial goals of the solution
The first goals of the solution were to focus on connecting to a range of data sources on the factory floor. This included installing proximity sensors and PLCs to track movements of product along the production line without interfering with the proprietary controllers, and ERP to have visibility around shifts schedules and production targets. All of this data was to be collected in real-time and sent to the Rayven cloud where it would be compared with the data from the factory floor to ensure data quality and integrity. This would deliver the following solution features:
- Monitoring of critical operational data received from the equipment via a web-based and mobile system
- Device management monitoring of PLCs and Gateways that are in place
- Ability to define business logic to reach the organization’s OEE rules
- Provide alarm and alert notifications via email or SMS messages when there was downtime, or when OEE below target
- Deliver real-time OEE metrics on iPads on the factory floor as well as the capability to input downtime reasons
- Connection with the ERP system to collect daily targets and shift schedules
- Test the application, making sure all of the above goals are met, based on the below solution architecture
Before setting the solution live, we tested four critical aspects of the solution:
The Rayven IoT platform is built with security as a top priority and our proprietary security architecture ensures that data is secure at all points of the IoT environment.
The solution includes data encryption in transit from device-to-cloud, as well as device authentication; security (Bearer) tokens; SSL, AES and RSA encryption; as well as additional device security checks done via automated polling.
Once the proximity sensors were installed and connected to PLCs, a Wi-Fi connection to a 4G Gateway proved to be the best solution. The combination of a secure and encrypted transmission path together with a dedicated, direct connection (that eliminates connecting into the factory’s network) meant that a fast and secure connection w=could be established without the need to involve IT.
Once connectivity was established and data started flowing consistently to the Rayven cloud, the next important process was to validate that the data from the factory floor matched the data being processed on the Rayven IOT cloud platform. In addition, all of the business logic and calculations were tested to ensure that decisions would be made based on reliable, accurate information
Industrial data science
The objective of exploratory data analysis was to observe trends in the data and compare them with what was happening on the factory floor, which included:
- Real-time OEE by shift, day, line, and product
- Dual and target shift production displayed as pitch charts
- Cost of downtime
- Shift efficiency, based on targets and shift comparison
- Reasons for downtime trends, by shift, day, line, and product
After providing initial insights, optimization alterations were made accordingly and the factory is now in the planning phase to expand the solution to additional lines and into three other facilities, with the goal of providing a cross-facility view for senior management.
Data sources used to deliver OEE Dynamix - our Manufacturing OEE IoT solution
New and existing data was used to create the custom applications and business insights that come from our Manufacturing OEE IoT solution.
Key features of our Manufacturing OEE IoT solution
All of these features were customized to fit the customers specific business objectives through our Manufacturing OEE IoT solution, but it's very easy to adjust and set-up your own goals using our pre-built solution, OEE Dynamix.
Display actual output in continuous real-time displays on the shop floor or head office. Compare actual vs. planned with real-time pie charts.
Monitor OEE continuously in real-time from any location. Identify problems early and act while production is still running.
Reasons for downtime
Record every downtime event automatically and record additional operator inputs on an HMI or iPad. Assess problems in real-time or analyze by shift, line, day product etc. as part of your continuous improvement program.
Operators can see where production stands vs. targets in real-time charts and color-coded numerical displays.
Alerts and notifications
Receive immediate alerts by Andon, SMS, or email when production or OEE falls below threshold.
Use the built-in schedule tool to identify when shifts start and end, when planned maintenance or breaks are scheduled.
The business outcomes from Rayven's Manufacturing OEE IoT solution
Any unplanned stoppages reduce your output or force you to work overtime. Understand the causes of downtime and drive uptime improvements.
Understand the causes of yield losses and rework so that you can drive the continuous improvement of your production lines.
Better energy efficiency
Change energy from an overhead to a direct cost by comparing real-time energy consumption with output. Learn how stoppages, changeovers and breaks all drive energy waste.
Quality defects can be isolated by location on a line, providing you with information vital to quality improvement actions.
OEE helps you to drive uptime and throughput on each and every line, helping you to maximize your ROA.
Better staff engagement
By placing data in the hands of your staff and engaging them in the collection of it via easy-to-use tools, you’ll improve engagement in continuous improvement and drive better outcomes.
