Although often overshadowed by breakdowns and other unplanned downtime, strategically managing planned downtime can boost your factory’s efficiency and production capacity. In this article, we’ll show you how to optimize this KPI with Industry 4.0 solutions like the Mapex MES.
In manufacturing, attention is typically focused on unplanned downtime due to its immediate impact on production processes.
However, planned downtime is equally important. Strategic management of this KPI can be a game-changer when it comes to improving overall efficiency and production capacity in industrial companies.
In this article, we explore the main causes of planned downtime and share tips on how to reduce it with the implementation of the Mapex MES solution.
What is planned downtime?
Planned downtime is the period during which a machine, production line, or industrial process is intentionally stopped to carry out pre-scheduled activities.
These interruptions are necessary to ensure the proper functioning and maintenance of equipment and processes, as well as to meet specific operational requirements.
The main causes of planned downtime include:
- Preventive maintenance: inspections, adjustments, or part replacements to prevent unexpected failures.
- Format changes: machine setups or adjustments to accommodate new products or batches.
- Cleaning and sanitation: processes particularly critical in industries like food or pharmaceuticals.
- Scheduled production stops: adjustments due to low demand or changes in factory scheduling.
- Inspections and audits: verifications to ensure regulatory compliance or quality standards.
The impact of scheduled downtime on OEE
As we discussed in this article, OEE measures overall equipment effectiveness by considering three factors: availability, performance, and quality.
Planned downtime directly affects availability, meaning that optimizing it can significantly improve this key indicator.
Why include planned downtime in OEE calculations? While it might be tempting to exclude these stoppages from OEE calculations to reflect a higher score, this can create an unrealistic perception of operational efficiency.
For example: if a format change usually takes 30 minutes but occasionally extends to 45 minutes, that difference should be seen as an improvement opportunity. Establishing standards for each planned activity and measuring compliance can help uncover hidden inefficiencies.
Strategies to optimize planned downtime
Reducing planned downtime doesn’t mean eliminating it but rather managing it more effectively to minimize its impact on production. Here are some practical tips:
- Schedule preventive maintenance during low-demand periods or outside peak production hours, and use tools like Mapex’s CMMS to prioritize tasks based on equipment criticality.
- Implement methodologies like SMED to significantly reduce changeover times and use an MES platform like Mapex to monitor and analyze the effectiveness of your continuous improvement actions.
- Define and establish production standards for each process, digitize and centralize necessary documentation in Mapex to streamline information searches, and reduce interruptions during complex tasks, audits, or quality inspections.
- Train operators to become more efficient in carrying out planned activities and promote a culture of continuous improvement where everyone seeks to reduce downtime and boost productivity.
Optimizing planned downtime not only improves OEE but also increases production capacity and factory profitability. Implementing strategies such as smart planning, changeover time reduction, and advanced technological solutions can make a significant difference.
Additionally, reducing unplanned downtime with tools like the Mapex MES solution is an essential step toward ensuring more efficient and competitive operations. Leverage technology and data to turn downtime into an opportunity for continuous improvement.
