In addition RCMCost identifies critical failure modes and compares the cost, safety and operational benefits of different maintenance intervals.
The program may be used to filter the most critical item (component) failures before detailed maintenance decisions are made.

This diagram may be extended to represent critical functions, their functional failures and their causes (engineering failure modes). System effects are identified which contribute to outage and operational costs as well as safety and environmental risks. The relative severity of different effects is identified by the user. This structured method for identifying failure modes and linking them with their effects on the system is known as Failure Mode Effects and Criticality Analysis (FMECA) and is a powerful analysis process in its own right. The RCMCost module allows flexible user-defined reports to be produced highlighting the most important contributors to operational costs and safety and environmental risks.

Other Features of RCMCostRCMCost provides a database facility for storing failure data, maintenance parameters, spares information and maintenance crew details. This data is used to provide advisory information based on simulation models incorporated in the program. For example, different maintenance intervals may be compared for their effect on maintenance and operational costs. The user may then record the decision on which maintenance policy (if any) to adopt. This decision may include combinations of:

What Standards are Included in the RCMCost Module?RCMCost supports Reliability Centered Maintenance standards such as SAE JA1011, MSG-3 and MIL-STD-2173(AS) by providing a structured method for entering FMECA data and simulating the effects of different maintenance strategies on cost, safety the environment and operational issues. The RCM decision making process is therefore substantially enhanced by the ability to quickly simulate the effects of preventive tasks, inspection tasks and condition monitoring taken into account ageing, hidden failures, maintenance crew costs, spares costs and availability etc. Standards and Decision DiagramsReliability Centered Maintenance decision diagrams are utilized in SAE JA1011, MSG-3 and MIL-STD-2173(AS) to provide a logical process for workgroups to determine what type of maintenance strategy to adopt for a given failure cause. The diagrams ask questions which often require analysis before a conclusion may be reached. In addition these diagrams follow a sequential process which may not be appropriate in identifying the optimal task or combinations of tasks for a given failure cause. However, RCMCost provides the full flexibility required to allow users to quickly compare the effects of different practical maintenance strategies and condition monitoring using well-known scientific methods. The RCMCost module may be used to produce reports similar to those in the SAE JA1011, MSG-3 and MIL-STD-2173(AS) standards. Reports may contain FMECA data, maintainability data, RCM decision data etc. As new data is gathered during the plant lifetime or system design changes are made RCM related data may be easily modified and maintenance procedures may be adjusted to reflect the living status of the plant. |
