Series changes are an unavoidable reality in many production lines, but they present a major challenge when it comes to optimizing Overall Equipment Effectiveness (OEE). The time lost during these transitions can significantly reduce your equipment availability, creating a bottleneck that impacts productivity. Delayed operations, pressure on delivery schedules, and increased costs make this issue critical for any factory seeking to maintain its competitiveness. In this context, better managing series change time is not just an option, but a strategic necessity.
The underlying causes of prolonged changeover times can be multifaceted, ranging from poorly defined preparation processes to inadequate personnel training. Faulty synchronization between teams can exacerbate delays as each delay directly impacts TRS/OEE. It is also a factor that affects the final product quality if adjustments are not calibrated with precision. The immediate consequence is a risk of repeated micro-stops, which, accumulated, heavily weighs on your industrial performance and affects your operational costs.
To address this issue, several solutions can be considered. First, the implementation of Lean methods such as SMED (Single-Minute Exchange of Dies) can significantly reduce changeover times. In parallel, digitalization of the production floor through solutions such as those offered by TeepTrak, enables real-time monitoring of operations, facilitating analysis of downtime and continuous improvement of TRS/OEE. The application of value maps and optimization of planning can also yield significant gains. It is essential to track key indicators such as equipment availability and performance to adjust in real time.
Consider a production line in a bottling facility that historically had series changeover times of 45 minutes. By applying SMED and adopting TeepTrak’s digitalization solutions, the facility measured specific steps and implemented targeted actions to progressively reduce this time to 20 minutes. Initially, teams followed the changeover steps to identify time losses. Adjustments were then made, including better tool organization and specialized training. The result was a significant increase in OEE and a notable reduction in production costs.
For any company wishing to embark on optimizing series changes, the first step is to precisely measure current times and identify specific blockage points. Thus armed, prioritize quick wins such as process standardization and team training. Do not forget to structure a TRS/OEE monitoring project using advanced systems like those from TeepTrak, which offer multi-line visibility and effective management of your continuous improvement. By engaging a structured action plan, you can transform losses into measurable gains, and thus improve your industrial performance sustainably.
FAQ
Question 1: How to optimize series changes to improve OEE?
To optimize series changes, start by identifying time-consuming steps, then apply Lean methods like SMED. Targeted training and real-time digitalized tracking are also essential.
Question 2: What impact do series changes have on OEE?
Series changes directly impact equipment availability, reducing TRS/OEE when transitions take too long, which can generate downtime and affect quality and costs.
Question 3: Where to start to structure an OEE optimization project?
Start by measuring your current performance and identifying bottlenecks. Prioritize quick wins, standardize processes, and use tools like those from TeepTrak for continuous monitoring.
