Transcript of Asset Performance

What do we mean 'Asset Performance?'
Maximise 'usefulness' of an asset
Minimise cost of providing that usefulness
Simple...
....right?
Functionality
...Defining 'performance' matters
Can be qualitative and/or quantitative, and can include:
How much?
How often?
For how long?
When?
Where?
To what standard / quality?
Under what conditions / constraints?
What things must happen?
What things must not happen?
...but how much is just enough?
Success vs. Failure
...mutually exclusive?

...the easy one
Example - driving to work:
Mission:
Arrive at work by 8:30
Success Space
...trickier
Assets can fail...can they succeed?
is success
the absence of failure?
the achievement of objectives?
both?
are we talking about service levels?
can we agree??
What do we want?
How do we get it?
Deliver the asset
Deliver the benefits
Keep delivering
the benefits
No more benefit
Decisions - Predicting the Future
...are we guessing?
Confidence and Risk
...this is the real world
Example - Drive to Work
...by 8.30, no later than 9.00
25km
50km/hr limit
= 25/50 * 60minutes = 30 minutes
...total success every time!
...right?
...but how confident are we?
= leave at 8:00
Probability of arrival time if leaving at 8:00am
Probability
How much confidence is enough?
Let's make some predictions!
Why is this useful to know?
Because now we can identify and evaluate improvements!
Accident (death)
Accident (car damaged)
Accident (no damage)
Flat Tyre
Wipers inoperative
Traffic
Hubcap lost

Options
Safer car, safer driving
more robust car / cheap to repair
cautious driving?
durable tyre / practice changing?
maintenance practices?
leave earlier?
tie the cap on?
...but WHEN should we do this?
Greatest opportunity to influence is at CONCEPT phase
Case Study
Mining Port Simulation
Note: example photos only
Purpose of the study
Annual production increase projected
can the infrastructure keep up?
If not, what can be done that will?
Model Scope
Success and Failure
...what is success?...how can we fail?
...is this a push or pull system?
...how do components perform or behave?
...how predictable are their behaviours?
...what can we change?
...what are the options?
Example Results
(Year 0) Base Case
(Year 7) Do Nothing Case
(Year 7) Increased Shiploader Rate
(Year 7) Additional Barge
(Year 24) Upgraded Barge Offload + Shiploader Rates
(Year 7) Inc. Shiploader Rate + Dredged Channel
Case Comparison
Findings
For the Year 7 production period
Most effective single improvement is the addition of another barge

Shiploader enhancement
Marginal additional benefit in Year 7

Improving the barge offloading rate
Better than the Do Nothing case
Not enough to prevent a near certainty of overflow

Combination of a 0.5m dredge and an enhanced shiploader
Appears to be an effective option.
Of the options that avoid the provision of major additional infrastructure such as a barge or additional shiploader, this is the best performing option.

By Year 28
An additional barge is a requirement to keep up with throughput
may be good enough on its own
Addition of a second shiploader by Year 28 gives good confidence that overflows can be avoided.

Summary
Recap!
Asset Lifecycle
...put the work in early - save effort and cost in the long run
Success and Failure
...understand success and failure for your assets
...be holistic in the events you consider
...consider events within and outside your direct control
Confidence and Risk
...better understanding of the asset's performance improves both
What about asset type?
