OEE Analysis

Overview:

The OEE (Overall Equipment Effectiveness) Analysis page in Busroot provides a comprehensive view of how well manufacturing equipment and processes perform compared to their maximum potential. It is designed for production managers, engineers, and operations leaders who need actionable insight into availability, performance, and quality losses in real time. The main problem it solves is making historically hidden production losses transparent, enabling users to identify, quantify, and address inefficiencies and boost manufacturing productivity.

Use Cases:

• Continuous Improvement Leader: Reviews shifts, days, or stations with the lowest OEE scores to focus improvement efforts and drive lean initiatives.

• Maintenance Planner: Uses OEE loss breakdown (downtime, performance, quality) to identify where planned maintenance or upgrades will yield the most benefit.

• Line Supervisor: Monitors daily OEE trends to react quickly when any KPI falls below threshold and ensure targets are met.

Functionality:

• OEE Dashboard/Chart: Visualises overall OEE and its three core components: availability, performance, and quality. Each breakdown is shown as a percentage and absolute loss.

• Filtering/Breakdown: Data can be filtered by plant, station group, or individual station level. Further breakdown includes schedule loss, maintenance loss, and unplanned downtime loss.

• Inputs: Requires production schedules, downtime thresholds, and output counts for both good and bad parts. Targets and cycle times per SKU should be up to date for accuracy.

• Loss Categorisation: Separately shows losses from equipment not scheduled (schedule loss) and planned non-production (e.g., maintenance).

• No Setup Required: OEE calculation is automatic, using existing schedules and production data. Access to full functionality may depend on user permissions and accurate setup of scheduling and devices.

• Trends and Comparison: Enables users to compare OEE trends over time and across machines, identifying recurring issues or opportunities.

• Limits/Prerequisites: Data accuracy relies on properly configured cycle times, schedules, and downtime thresholds. OEE only considers time when production is planned, excluding planned maintenance and out-of-shift times.

Data Setup:

• Make sure machines and downtime reason codes are fully configured.

• Input correct shift schedules, production targets, and loss categories.

Formula:

• OEE = Availability × Performance × Quality, where:

  • Availability = (Run Time / Planned Production Time)

  • Performance = (Total Pieces × Ideal Cycle Time) / Run Time

  • Quality = Good Pieces / Total Pieces
