为什么说维护 KPI 指标很重要？
维护 KPI 是评估维护流程绩效，进而发掘改进潜力的重要衡量指标。它能够清晰展现维护活动的效率、生产率和质量。通过衡量和遵守 KPI，企业可以提高维护活动效率、缩减停机时间、提高设备可用性、优化整体绩效等。
衡量 KPI
衡量维护 KPI 指标时，选择与企业特定目标和需求相符的正确指标很重要。制造行业存在大量 KPI 指标，但并非所有 KPI 都与您的企业相匹配。选择和衡量 KPI 时，注意遵守以下步骤：
1. 为您的企业和战略定义明确的目标：制定可量化衡量且愿为之努力的具体目标。
2. 采集相关数据：确保掌握衡量 KPI 所需的可靠数据源。
3. 报告和分析：使用 CMMS 对采集到的数据进行分析并生成有意义的报告。这样一来，不但能随时掌控发展趋势，还能发现偏差，进而制定改进措施。
CMMS 与 KPI 报告
在维护 KPI 的采集、管理和报告方面，CMMS 为您提供高效的解决方案。下文介绍几种 KPI 并阐述 CMMS 如何帮助提高 KPI 指标。
1. Mean Time Between Failures (MTBF)
The MTBF indicates how long a system operates on average between two failures. It is calculated by dividing the operating time by the number of failures. A higher MTBF value means that a system operates longer before it fails. This is an important indicator of the reliability and availability of systems.
To improve the MTBF, it is important to analyse the causes of failure and take preventive maintenance measures. A CMMS enables you to record downtime, identify the causes of failures and plan preventive measures.
2. Mean Time To Repair (MTTR)
The MTTR indicates how long it takes on average to repair a system once a failure has occurred. It is calculated by dividing the total downtime by the number of failures. A low MTTR value means that failures can be rectified quickly, resulting in shorter downtime.
Some businesses also differentiate between the Mean Time To Repair and the Mean Time To Recovery as a maintenance KPI. The time to recovery describes the time required to return a system to normal operating status after a failure. In contrast to the Mean Time To Repair, which focuses on the repair time, the Mean Time To Recovery refers to the time required to restore the system to full functionality, including diagnostics, purchasing spare parts and carrying out all necessary measures (see graphic).
A CMMS enables you to record and analyse repair times in order to improve the MTTR. Does diagnostics take a long time? Is it the repair process itself or the wait for the right spare parts? By monitoring and analysing repair times, you can identify bottlenecks and inefficient processes and determine measures to shorten repair times.
3. Overall Equipment Effectiveness (OEE)
The OEE is one of the most important key figures for evaluating the overall performance of a system and production. It takes into account the availability, performance and quality of the system. A high OEE value indicates that production and system performance are efficient and reliable.
Festo AX Smartenance and Key Performance Indicators (KPIs)
Festo AX Smartenance is a CMMS that has been specially developed for and with maintenance staff to keep an eye on your maintenance processes and maintenance KPIs. You can use AX Smartenance to record and analyse data and generate reports. It offers a user-friendly interface and extensive functions for managing your maintenance activities.
How can Festo AX Smartenance improve maintenance KPIs?
CMMS AX Smartenance offers an effective way to improve maintenance KPIs (MTBF/MTTR/OEE) and optimise maintenance performance. Here are some ways in which AX Smartenance can help you:
- Data acquisition and process automation
AX Smartenance automates data acquisition and processes such as maintenance planning, allocating work orders and reporting. - Quickly provides all the necessary information
Such as circuit diagrams, suggested solutions and detailed information. Anytime, anywhere thanks to the mobile app. - Real-time monitoring
This allows you to react to problems at an early stage and minimise downtime. Bottlenecks can be avoided and inefficient processes identified so that targeted measures can be taken. - Reporting and analyses
You can generate detailed reports on downtime, repair times, maintenance activities and other relevant data. These reports help you to identify bottlenecks, improve inefficient processes and make informed decisions to optimise maintenance performance.
Conclusion
A CMMS offers an effective way to improve maintenance KPIs (MTBF/MTTR/OEE) and optimise maintenance performance. You can increase the efficiency of your maintenance processes, reduce downtime and improve the performance of your systems thanks to all relevant information being available wherever you are, as well as data gathering and analysis, automation of processes, real-time monitoring and comprehensive reporting functions.
