In the industrial sector, equipment efficiency is crucial for maintaining high competitiveness and optimal profit margins. Low availability often becomes the primary brake on increased performance, directly impacting TRS/OEE (Overall Equipment Effectiveness). Lack of availability, due to unplanned downtime and poor equipment management, can lead to serious production delays and increased costs. Mastering the formula for “availability” in OEE is therefore essential for any factory aiming to maximize its productivity. This key indicator makes it possible to quantify and improve the productive time of machines.
The causes of low availability can be multiple. Frequent breakdowns, waiting for spare parts, or inefficient production changes are often to blame. These factors generate unforeseen and prolonged stoppages, negatively affecting overall productivity. By reducing availability, these interruptions increase the unit cost of production and decrease the ability to meet production schedules, which directly affects TRS/OEE. Factories without real-time monitoring struggle to quickly identify these issues, further aggravating the situation.
To counter these challenges, several solutions can be implemented. The adoption of continuous improvement methods such as Lean manufacturing and Total Productive Maintenance (TPM) can significantly reduce downtime. Integrating digitalization tools, such as those from TeepTrak, offers real-time visibility and in-depth analysis of downtime, allowing for quick response. Investing in real-time performance tracking systems such as PerfTrak OPC UA from TeepTrak enables effective TRS/OEE management by optimizing visibility across multiple production lines.
A concrete example is an automotive factory that, faced with frequent and unforeseen stoppages, implemented a real-time tracking system with TeepTrak. By analyzing the collected data, the factory was able to identify that 30% of its downtime was due to tooling change issues. By applying TPM methodologies and efficiently reprogramming its processes, it reduced its downtime by 25%, thus improving its availability rate, and consequently, its OEE.
In conclusion, for any industrial company seeking to improve its performance, a focus on availability, one of the three key components of OEE, is crucial. Start by measuring rigorously using appropriate tools and define priority actions based on accurate analysis. Integrating solutions like TeepTrak can significantly strengthen the sustainable and continuous performance of your production lines. By following these principles, you open the door to increased productivity and lasting competitive advantage.
FAQ
Question 1: How is availability calculated in OEE?
Availability is calculated by dividing Planned Production Time by Total Time and multiplying the result by 100. This percentage reflects the time during which the equipment is actually productive.
Question 2: What impact does low availability have on OEE?
Low availability leads to frequent stoppages, reducing productivity and increasing operating costs. This compromises the overall efficiency (OEE) of the equipment.
Question 3: Where to start to improve equipment availability?
Start by analyzing the root causes of downtime, invest in real-time monitoring systems like those from TeepTrak, and apply continuous improvement programs such as TPM.
