Slide 1

Maintenance (CBM) Decision Optimization using the CMMS/EAM, and the reliability (RCM) knowledge base

Enhance the impact of our current CBM/Maintenance initiatives

Implement living reliability knowledge management

Drive continuous maintenance decision improvement

2. Embodies a culture and viewpoint

Slide 3©2006 Optimal Maintenance Decisions (OMDEC) Inc.

The functions of maintenance (decision optimization) software

1. To build a decision model (a measuring stick) for interpreting condition monitoring data, optimally.

2. To deploy that model using an automated “intelligent” agent.

3. To verify the model’s performance and, to improve it continuously.

The viewpoint (culture)

Premise 1 Recorded information on what happened has

value

Premise 2 We may convert that information to practical,

structured reliability-centered knowledge1

Premise 3 Manage that knowledge using a dynamic,

continuous improvement process

1 Knowledge – the ability to make good, verifiable maintenance decisions.

What do we need on the work order for reliability analysis?

FF2

S3

PF1

1 Potential failure – has no or relatively minor consequences

2 Functional failure – has consequences resulting from loss of function

3 Suspension – a renewal of a failuer mode / component for reasons other than FF or PF

Benefits of living RCM

Unification of RA, RCMA, and Optimized CBM with the CMMS.

Residual life estimation and survival probability capability in CBM program

CBM decisions based on true asset condition.

Inherent measures of the effectiveness of those decisions.

Better communications through the use of RCM thinking in daily practice

Inherent continuous improvement

Slide 16©2006 Optimal Maintenance Decisions (OMDEC) Inc.

Achieving reliability requires us to perform three principal types of activities:

1. Monitor asset performance, 1. Tells us to what extent we are maintaining function.

2. Manage / grow / use reliability knowledge, 1. Tells what we need to do to maintain function

3. Analyze reliability.1. Tells us about asset failure behavior

2. So that we can refine the knowledge base
