This website provides information about reliability centered maintenance (RCM) and how it relates to reliability and maintainability (RAM) software and analyses.

Reliability Centered Maintenance (RCM) is the concept of developing a maintenance scheme based on the reliability of the various components of the system or product in question. Implementing a preventative maintenance program using RCM can greatly reduce the the cost of ownership of a product or system.

Developing an effective RCM program requires extensive knowledge about the reliability and maintainability of the system and all of its subsequent components. Important factors include the MTTR (Mean Time To Repair) and failure rate (total number of failures within a given time period) of the product or system.

RCM can improve the efficiency of the system undergoing maintenance, and all other products or processes that interact with that system. Developing an effective RCM program will optimize the maintainability of the system - allowing you to anticipate the times when the system is down for maintenance, and scheduling other activities or processes accordingly.

An important part of an effective RCM is to analyze the system or product using a Failure Modes and Effect Analysis (FMEA), which determines the different ways a system can fail. Other reliability and maintainability analyses which are important parts of RCM include Fault Tree Analysis (FTA), which shows the specific steps involved in a system failure, whether mechanical problem or human error, and Event Tree Analysis (ETA), which illustrates the different consequences of component or system failure.

Relex Software Corporation produces software that enables users to calculate the reliability information necessary to develop an effective RCM program. Relex Software is a leader in reliability and maintainability software analysis tools. We specialize in software, training courses, and seminars covering all aspects of reliability engineering. Our products are used by thousands of engineers worldwide in a variety of businesses.
