Reliability Centered Maintenance (RCM) was created to ensure a system continually works to the best of its ability in several different areas. RCM focuses on establishing the safe, minimum levels of maintenance. If implemented correctly, this should lead to increased reliability and uptime of machinery, cost-effectiveness, and a better understanding of the safety and risk involved in maintenance.

建立以可靠性為中心的維護（RCM），是為了確保系統在幾個不同的方面持續盡全力進行 運轉。建立以可靠性為中心的維護（RCM），專注于構建安全化、最小化的維護。如果得以正確推行，這將提升機器的可靠性和正常運行時間、成本效益，并讓我們更好地理解維修中所涉及的安全和風險。

RCM is a complete approach to maintenance, viewing it as the primary way to ensure a piece of machinery is working at its best. This is done by a specific procedure which assesses the machine critically, and then plans for appropriate and scheduled maintenance tasks. The RCM steps are then applied and kept under review, with changes made if needed, based on regular assessments.

以可靠性為中心的維護（RCM），是一種完整的維護方法，我們把它視為確保機器處于最佳工作狀態的主要方法。以可靠性為中心的維護（RCM），是通過對機器進行關鍵評估的某個特定程序來完成的，然后，為適當的、規劃的維護任務制定計劃。然后，根據定期評估，運用以可靠性為中心的維護（RCM）的步驟，而一旦有必要，我們需要進行變更。

以可靠性為中心的維護（RCM）步驟

When beginning to apply RCM, there are set questions which need to be addressed:

運用以可靠性為中心的維護（RCM）時，以下有一些問題是需要提出來的：

-What are the item’s functions? (both primary and secondary)

-機器的功能是什么？（一級和二級）

-How could it fail to do said functions?

-這些功能為何發生故障了呢？

-What causes failure?

-是什么導致了功能故障？

-What happens during a failure? (i.e. is it a full failure of the machine not doing its primary function, or just a slowing down of that function)

-故障期間，發生了什么？（也就是說，機器沒有發揮其主要功能的完全的故障，或者僅僅是功能變慢）

-Does the failure matter, and to what degree?

-功能故障是否嚴重，達到了什么程度？

-What can be done to prevent the failure?

-為防止功能故障，我們能做什么？

-What must be done if failure prevention is not successful?

-如果功能故障預防并不成功，那么，我們必須要做什么？

RCM is often used to ensure cost-effectiveness in a machine, as well as to measure how critical a failure of a machine is. That means if one part of a machine fails, but that part is not critical, it is allowed to fail. The main functions of the machine receive priority, and are preserved as much as possible to help ensure it completes its primary role at all times.

以可靠性為中心的維護（RCM），通常用于確保機器的成本效益，以及衡量機器故障的嚴重程度。這意味著如果機器的某個部件發生了故障，即便該部件并不重要，也會發生故障。機器的主要功能處于優先重點的地位，要盡可能地保留，以幫助確保機器始終完成其能主要任務。
