In today’s industrial landscape, measuring Overall Equipment Effectiveness (OEE) has become essential to improve production line performance. One of the primary factors of OEE is availability, which reflects the time when equipment is actually operational compared to planned production time. Yet many factories struggle to calculate this availability accurately, compromising their ability to maximize productivity and reduce costs. Understanding and rigorously calculating availability can radically transform operations, particularly in a competitive environment where every minute of downtime can weigh heavily.
The underlying causes of availability calculation problems are multiple. Often, there is an insufficiency of real-time tracking systems that reliably capture data. Furthermore, unplanned downtime, lengthy changeover times, and unreported minor interruptions contribute to inaccurate data. These factors lead to an underestimation of availability, negatively affecting TRS/OEE, increasing downtime and amplifying unplanned maintenance costs. Consequently, not only does production efficiency drop, but quality can also suffer due to lack of operational synchronization.
To address these challenges, it is crucial to implement advanced systems enabling continuous and automatic equipment monitoring. Shop floor digitalization with tools such as those offered by TeepTrak, for example, enables real-time analysis of downtime and provides visibility across multiple lines. Continuous improvement methodologies such as Lean or Total Productive Maintenance (TPM) are complementary. They help identify bottlenecks, standardize rapid restart procedures, and establish relevant KPIs to track availability.
A concrete example comes from an automotive component manufacturing company that used TeepTrak to address its availability issues. By integrating TeepTrak solutions enabling real-time performance tracking, and training operators to recognize and quickly report micro-stops, the factory increased its availability rate from 80% to 92% in six months. The precise and continuous data also made it possible to identify equipment with recurring failures, even justifying replacement with more reliable equipment.
In conclusion, to significantly improve availability in TRS/OEE calculation, manufacturers must first invest in advanced tracking systems and commit to a continuous improvement approach. Expected benefits include a notable increase in productivity, improved quality, and reduced costs associated with unplanned downtime. A structured approach, integrating tools such as those from TeepTrak, will not only enable better measurement and performance analysis, but also drive continuous improvement toward more efficient and resilient industrial processes.
FAQ
Question 1: How do you calculate availability for OEE?
To calculate availability in OEE, divide equipment operating time by planned production time. Integrate real-time tracking tools for accurate measurements.
Question 2: What impact does availability have on TRS/OEE?
Availability is a key factor in TRS. It directly influences downtime and, consequently, productivity. Accurate measurements enable you to identify and reduce bottlenecks.
Question 3: Where do I start to improve availability in my factory?
Start by auditing your current tracking systems, then consider integrating digitalization solutions. Training personnel in TPM practices and standardizing processes are also essential.
