What is OEE?
Overall Equipment Effectiveness (OEE) is a standard metric developed as part of Total Productive Maintenance (TPM) methodology to quantify equipment performance. It combines three essential manufacturing metrics:
Availability
Operating Time vs Planned Time
Performance
Actual Speed vs Planned Speed
Quality
Good Units vs Total Units Produced
System Topology

Key Points:
- PLC connected to machine sensor to collect produced quantity
- HMI is used by field operator to enter operator ID, downtime and/or reject codes
- Downtime and reject codes is synced with database server
Web Application Features
Dashboard

- Real-time OEE Monitoring – Instantly track Overall Equipment Effectiveness with clear performance metrics
- Breakdown of OEE Components – Availability, Performance, and Quality displayed separately for deeper analysis
- Shift & Line Performance Analysis – Compare OEE by production line and shift to identify trends and inefficiencies
Machine Monitoring

- Production Output vs. Target – Easily compare actual quantity produced against set targets
- Real-time Machine Status – Instantly see which machines are Running, Idle, or Down
- OEE Performance per Machine – Monitor each machine's efficiency
- Downtime Identification – Quickly detect and respond to machine downtimes
Reports

- OEE Performance Trend – Track efficiency and consistency over time
- Downtime Analysis – Breakdown of different downtime causes
- Reject Analysis – Categorized defective products analysis
- Date Range Filter – Analyze production data for specific periods
- Export Report - Custom format exports available
Master Data

- Comprehensive Data Management: Machines, Time Shifts, Downtime Codes, Reject Codes, User Access Control
- Synchronized with HMI systems
- Role-based access control (admin/supervisor)
