RELIABILITY CENTERED MAINTENANCE
Reliability Centered Maintenance (RCM), If it is applied correctly, RCM transforms the relationships between the undertakings which use it, their existing physical system and the people who operate and maintain those systems. It also enables new systems to be put into effective service with great speed, confidence and precision.
WHAT IS RELIABILITY CENTERED MAINTENANCE (RCM)?:
RCM is an analytical process to determine the appropriate failure management strategies, including PM (Preventive Maintenance) requirements and other actions that are warranted to ensure safe operations and cost-wise readiness. With few exceptions, preventative maintenance (PM). A Preventive Maintenance (PM) program is based on the assumption of a "fundamental cause-and-effect relationship between scheduled maintenance and operating reliability.
Reliability Centered Maintenance (RCM) is the optimum mix of reactive, time- or interval-based, condition-based, and proactive maintenance practices. The RCM’s design process uses development strategies outlined in SAE JA1011, SAE JA1012, NAVAIR 00-25-403, SAE J1739, MIL-STD-1388, MIL-STD-780, MIL-STD-1390, MIL-STD-1629, MSG-3 and MIL-HDBK-2173.
RMS Aerospace can provide the following RCM assistance:
- Task Analysis (TA)
- Preventive Maintenance Task Analysis (PMTA)
- System Configuration Analysis (SCA)
- Functional Failure Analysis (FFA)
- Failure Effect Analysis (FEA/FMEA)
- Task Interval Analysis (TIA)
- Maintenance Cost Analysis (MCA)
- Task Packaging Analysis (TPA)
- Equipment Selection Analysis (ESA)
TASK ANALYSIS (TA):
The task analysis TA provides a concise narrative of significant value to any given program. The key functions of the task analysis process has five distinct functions, classifying tasks to skill set, identifies maintenance tasks, prioritizes tasks and the sequencing of tasks. Task analysis can also mean figuring out what more specific tasks a users must do to meet those goals and what steps they must take to accomplish those tasks.
PREVENTATIVE MAINTENANCE TASK ANALYSIS (PMTA):
The task preventative maintenance analysis PMTA provides a concise narrative of significant value to any given programs preventative maintenance process. The key functions of the preventative maintenance task analysis process has same functions as the task analysis, however, the focus on this analysis is on PM tasks only, Preventative task analysis can also mean figuring out what more specific tasks a users must do to meet operational stability of a given system.
SYSTEM CONFIGURATION ANALYSIS (SCA):
RCM requires elements of the system configuration analysis (SCA) in developing the final RCM reports. System configuration is paramount in defining proper maintenance actions.
FUNCTIONAL FAILURE ANALYSIS (FFA):
Performing the functional failure analysis FFA makes it easy to define and view the functions that equipment is intended to perform, the ways that equipment may fail to perform and its intended function (Functional Failures), the Effects of a failure and the specific (actionable) Causes of a failure (also called Failure Modes). FFA analysis approaches include an evaluation of the consequences of potential failures.
FAILURE EFFECT ANALYSIS (FEA/FMEA):
Failure Effects Analysis FEA also called Failure Modes and Effects Analysis FMEA is methodology for analyzing potential reliability problems early in the development cycle where it is easier to take actions to overcome these issues, thereby enhancing reliability through design. FMEA is used to identify potential failure modes, determine their effect on the operation of the product, and identify actions to mitigate the failures. A crucial step is anticipating what might go wrong with a product. While anticipating every failure mode is not possible, the development team should formulate as extensive a list of potential failure modes as possible.
TASK INTERVAL ANALYSIS (TIA):
The task interval analysis TIA goes beyond task cost calculations based on MTBFs and the often-inappropriate assumption of an exponential failure distribution to caculate task intervals. We use the Weibull, exponential, normal, lognormal or mixed Weibull distributions to describe the equipment's failure behavior and then use the same powerful calculation and simulation engines.
MAINTENANCE COST ANALYSIS (MCA):
Maintenance Cost Analysis MCA calculations are tailored to the specific requirements of the following maintenance strategies; run failure, repair replacement, service, failure finding inspection, and oncondition inspection. The Cost per Operating Time, Average Availability and Total Operating Cost over the life of the equipment provide a valuable tool for selecting the most appropriate and cost-effective maintenance approach.
TASK PACKAGING ANALYSIS (TPA):
RCM makes it easy to group individual tasks into packages based on interval, labor requirements, etc. You can manually assign a task to the appropriate maintenance package and/or allow package tasks based on the criteria that you have specified for each task package. Combined with the TPA is also the Equipment Selection Analysis TPA which identifies peculiar support equipment and special test equipment.
