Overall Equipment Effectiveness Index

Overview

Overall Equipment Effectiveness (OEE) is the most commonly used metric to understand, measure, and improve manufacturing productivity, providing insights into the efficiency of a manufacturing process by evaluating key aspects of equipment performance.

This technology offers a unique IoT solution to this challenge by extracting production equipment status from the equipment tower light signals by means of a sensor node connected to a light sensor in a non-intrusive manner. No meddling with existing machine circuitry is needed. A key feature of this technology is the integrated built-in Human Machine Interface (HMI) on the sensor node for operators to provide inputs on the machine's non-operation. Comprising cost efficient hard buttons for user.

Unique value proposition

This technology offers a low-cost and safer way to digitalise legacy systems and ease OEE computation. It also provides legacy equipment with the capability to collate OEE index data for productivity analysis. Furthermore, it enables remote monitoring of the production alert and operations, which facilitates better management of operations for managers and supervisors.

Potential applications

The system is designed for legacy manufacturing equipment to collate data for OEE computation. The data are displayed in quality, performance, and availability for productivity analysis. This will be in accordance with OEE best practices for applicability beyond the manufacturing sector. Examples:

• Digitalisation of equipment in the manufacturing plant

• Reliability chamber for monitoring and alert

• Construction equipment and machinery

• Other legacy equipment for monitoring and analysis
