OEE VS OOE VS TEEP

Difference between OEE and other indicators

OEE vs OOE: What are the differences?

OEE (Overall Equipment Effectiveness) and OOE (Overall Operations Effectiveness) are two indicators often used to measure the performance of industrial equipment, but they focus on slightly different aspects:

– OEE measures the overall efficiency of equipment, taking into account availability, performance and quality, as explained above.
– The OOE, on the other hand, also includes losses linked to series changes and adjustments, providing a broader view of production losses.

These differences mean that the OOE can often appear to be a more severe indicator than the OEE, because it incorporates more factors that can negatively affect performance.

Importance of OEE in relation to other metrics

OEE is crucial because it provides a direct measure of equipment efficiency and a solid basis for continuous improvement. Compared with other metrics that may focus on isolated aspects of production, OEE offers a global perspective on three key components that are essential for any company seeking to optimise its manufacturing processes and reduce costs.

GUIDE

Setting up and monitoring the OEE

How do you set up an OEE monitoring system?

Setting up an effective monitoring system for OEE involves several key steps:

1. Definition of measurement parameters: It is essential to define precisely what will be measured and how, ensuring that the data collected is reliable and relevant.
2. Choice of monitoring tools: Using automated systems such as an MES (Manufacturing Execution System) can make data collection and analysis much easier.
3. Team training and involvement: Operators need to be trained to understand the importance of OEE and how their actions directly influence results.

Using the MES system to optimise OEE

An MES system helps to automatically collect the data needed to calculate the OEE, providing real-time information that enables rapid action to be taken to rectify inefficiencies. This type of system often incorporates advanced reporting and analysis functions, enabling constant monitoring and continuous improvement of production processes.

TOOLS

Indicators and causes of performance loss

Introduction to TEEPTRAK solutions

TEEPTRAK is a technological solution for monitoring and analysing equipment performance in real time. It offers a number of specific tools:

PerfTrak: to monitor machine performance.
QualTrak: to monitor product quality.
PaceTrak: to measure production rate.

Each tool enables operators to enter the causes of deviations directly via a tablet, making it easier to identify problems quickly and adapt processes.

Construction of performance indicators

The data collected by TeepTrak solutions is used to build robust performance indicators. These indicators help to understand the main causes of performance loss and to implement targeted corrective actions.

Performance loss nomenclature for OEE/TEEP

For effective monitoring of the OEE, certain categories of losses such as ‘production site stoppages’ and ‘planned downtime’ are generally not included in the calculation of the OEE, allowing the focus to be on avoidable losses and maximising operational efficiency.

Improving OEE: strategy and techniques

Using TPM to improve OEE

Total Productive Maintenance (TPM) is a proactive approach to maximising the efficiency of industrial equipment. TPM involves all employees, from production operators to maintenance managers, in a collective effort to reduce losses and improve machine performance. By integrating TPM into business strategy, organisations can achieve the following benefits to improve their OEE:

– Reducing unplanned downtime: Preventive maintenance enables problems to be detected and resolved before they cause production stoppages.

– Improved product quality: By maintaining equipment in perfect condition, TPM contributes to the production of high-quality parts, thereby reducing the scrap rate.

– Increased productivity: A well-maintained machine operates at optimum capacity, which increases overall performance.

SMED method and OEE

The SMED (Single-Minute Exchange of Die) method is a technique designed to reduce the time required for format or equipment configuration changes. SMED plays a crucial role in improving OEE, especially in production environments that require frequent production changes. The main benefits of applying the SMED method include:

– Reduced downtime: By reducing changeover times, downtime is minimised, which increases machine availability.

– Greater flexibility: With faster changeovers, it is possible to respond more effectively to fluctuating demand and to produce small series economically.

– Better use of resources: By optimising change processes, less time and resources are spent on non-productive activities.

Integrating Industry 4.0 for optimised OEE

Industry 4.0 represents the next wave of digital transformation in the manufacturing sector. The integration of advanced technologies such as the Internet of Things (IoT), artificial intelligence (AI), and cyber-physical systems can significantly transform the calculation and improvement of OEE. Here’s how Industry 4.0 can contribute to optimised TRS:

– Real-time monitoring: Sensors and IoT devices can monitor machine operating conditions in real time, facilitating accurate predictive maintenance and reducing unplanned downtime.

– Advanced data analysis: Using AI and the analysis of large quantities of data, it is possible to identify failure trends and optimise production processes to improve OEE.

– Increased automation: Robots and automated systems can take on repetitive or dangerous tasks, increasing performance and quality while reducing human fatigue.
