如果实施得当,RCA和RCM都同等重要且非常有效。它们两者具有不同的功能,但是当它们一起实现时,它们会彼此互补并增加系统的整体利益。
1.根本原因分析(RCA):
RCA是一种过程,用于确定缺陷或问题的主要原因,以便人们可以采取预防措施和步骤来消除或减少问题。
2.以可靠性为中心的维护(RCM):
RCM是用于确定最佳实施哪种维护策略的过程。
RCM和RCA之间的区别:
RCM | RCA |
---|---|
It identifies “What could cause a problem?”. | It identifies “What did cause a problem?”. |
It is generally required to identify maintenance requirement of any system. | It is generally required determine root cause of problem so that essential steps can be taken to reduce problem. |
It is proactive in nature. | It is reactive in nature. |
RCM is more costly and requires more time as compared to RCA. | RCA is less costly and requires less time as compared to RCM. |
It is driven by preventive maintenance strategies. | It is driven by maintenance prevention strategies. |
RCM basically treats symptoms of problems. | RCA basically identifies root cause of problem and then corrects it. |
It is a proactive tool that is used to prevent problem or failures before their occurrence. | It is a reactive tool that is used to prevent problems after its occurrence. |
It determines different ways in which a software might fail. | It determines why software has failed. |
RCM is highly used as compared to RCA because of proactive nature. | RCA is less used as compared to RCM because of its reactive nature. |
It starts with reliability initiative. | It starts when an incident occurs. |
