RCMCost Module

The RCMCost module in Availability Workbench provides the full framework for building the Reliability Centered Maintenance model to represent your plant.

Reliability Centered Maintenance (RCM) is a procedure for determining maintenance strategies based on reliability techniques and encompasses well-known analysis methods such as Failure Mode Effects and Criticality Analysis (FMECA).

RCM procedures take into account the prime objectives of a maintenance program:

Minimizing Costs
Meeting Safety and Environmental Goals
Meeting Operational Goals

Key Features

RCMCost provides the data management, reporting and analytical facilities for developing and maintaining a Reliability-Centred Maintenance (RCM) programme. These facilities include :

Graphically constructed system hierarchy diagram
Failure Mode Effects and Criticality Analysis (FMECA)
Identification of critical failure modes
Advice for decision making based on performance simulation
Redundancy modelling
Weibull analysis of field data
Optimisation plots for alternative maintenance strategies
Group maintenance modelling
Flexible reporting providing customised worksheets
Copy and paste facilities for data transfer
Import/Export to databases and spreadsheets

How does RCMCost Help?

RCMCost in Availability Workbench provides facilities for storing RCM data and analyzing maintenance alternatives. It provides simulation algorithms to predict lifetime maintenance costs, spares costs and usage, maintenance crew manning requirements, safety and environmental risks and operational performance. In addition RCMCost identifies critical failure modes and compares the cost, safety and operational benefits of different maintenance intervals.

The program is designed to combine well-established reliability prediction techniques with engineering experience. The program does not decide on which maintenance policy or combination of policies to adopt. Instead it advises the individual user or workgroup based on the operational data provided. The program may be used to filter the most critical item (component) failures before detailed maintenance decisions are made.
Constructing a Hierarchy Diagram

RCMCost provides interactive graphical facilities for constructing a hierarchical diagram representing the logical connection between the sub-systems and items constituting the overall plant or system. 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.
