Optimizing Performance-Based Maintenance Plans: Avoiding Premature Calls

Question:

When it comes to performance-based maintenance plans, it is essential to consider various factors before issuing a call. Currently, we are receiving orders before the measure point meets the required metric, indicating that the call may be based on a pre-calculated schedule. Our plans are structured with Call Horizon 100%, Early Shift 100%, and Late Shift 100%, with no consideration for tolerance. The key question here is how to avoid making a premature call based solely on estimated dates, and instead rely entirely on the measure point for decision-making. Your insights on this matter would be greatly appreciated. Thank you.

Perhaps the counter readings were not updated in a timely manner on the work orders.

After reviewing your description, it appears that we are experiencing similar challenges with "heartburn" in SAP configurations. This issue has been persisting for some time, affecting the accuracy of activity predictions and maintenance plan scheduling in SAP. The Annual Estimate plays a crucial role in determining call dates for maintenance, which in turn impacts when orders are generated. There are a few approaches to address this issue: 1. Manual intervention: Regularly update the Annual Estimate based on actual readings and adjust the plan schedule manually or through batch jobs (using IP10 or IP30). While this method provides a more realistic scenario, it can be time-consuming and may still result in issues depending on PM intervals. 2. Development: Utilize a user exit with development efforts to automate the updating of the Annual Estimate and maintenance plan rescheduling based on data from measuring documents. This approach may improve the situation to some extent, although challenges with intervals may still arise. 3. Interface integration: Implement a third-party solution to handle meter readings and trigger PMs based on established trigger points, providing a more efficient and effective solution. If you have come across any other effective strategies to address this issue, I would greatly appreciate learning about them!

To optimize scheduling efficiency, it is recommended to manually run the deadline monitoring program immediately after inputting counter readings, rather than relying on automatic scheduling. Set the call objects interval to zero days in SAP to prevent future predictions. By following this method, there will be no requirement to update annual estimates for schedule calculations.

When setting up a maintenance plan, make sure to select the option that requires one order to be finished before moving on to the next planned maintenance task. This ensures a systematic and efficient maintenance schedule.

To optimize your test plan, consider reducing the annual estimate to around 500 units and rescheduling it for a date in 2032. The plan will only be implemented if the counter surpasses the frequency specified in the plan.

It seems you're looking for a more adaptive and dynamic management strategy. One possible solution could involve leveraging predictive analytics. This would use real-time data to forecast future breakdowns or maintenance needs, which could help in determining the most effective moment to issue a call. It's an approach that goes beyond scheduled maintenance or absolute metrics, and it might be worth exploring - especially if early or late maintenance is causing inefficiencies in your operations.

Frequently Asked Questions (FAQ)

FAQ: FAQs:

Answer: 1. What are performance-based maintenance plans, and why are they important? - Performance-based maintenance plans are structured maintenance strategies that focus on the performance of equipment or systems rather than time-based schedules. They are important for optimizing maintenance efforts and resources by ensuring maintenance is carried out only when necessary based on actual performance metrics.

FAQ: 2. How can premature calls in maintenance plans negatively impact operations?

Answer: - Premature calls in maintenance plans can lead to unnecessary downtime, increased maintenance costs, and reduced equipment lifespan. By performing maintenance too early, resources may be wasted on components that have not yet reached the end of their useful life.

FAQ: 3. What factors should be considered to avoid premature calls in maintenance plans?

Answer: - To avoid premature calls, it is essential to consider factors such as the measure point meeting the required metric, setting appropriate tolerance levels, and relying on actual performance data rather than pre-calculated schedules. By incorporating these factors, maintenance decisions can be based on accurate information rather than estimates.

FAQ: 4. How can maintenance plans be optimized to rely entirely on measure points for decision-making?

Answer: - Maintenance plans can be optimized by adjusting Call Horizon, Early Shift, and Late Shift percentages to consider tolerance levels and ensure that calls are made based on actual performance data from measure points. By aligning maintenance schedules closely with equipment performance, premature calls can be minimized.
