True Downtime Cost


Data sources definition

Data Sources (Definition:)

  • A method of recording and analyzing all significant cost metrics associated with equipment downtime in a building or manufacturing facility.

  • TDC provides a way to assign time and/or monetary value to previously considered “non-tangible” cost of downtime.

  • Also TDC includes downtime factors commonly overlook to arrive at a more true value for the cost of downtime.

TDC – True Downtime Cost

Data sources overview

Data Sources Overview

Data – too much of it, not enough of it, inadequate quality or the wrong sort: and what is it used for anyway?

www.DowntimeCentral.com


Considerations of best metrics
Considerations of best metrics:

  • What you measure is what you’ll get!

  • Ultimately must be able to accurately track failure rates and allocate costs

    • individual machines (location, asset)

    • machine categories (motors, pumps)

    • components (bearings, seals)

  • Major benefits can be attained with current technology -- more effectively applied

    • lower cost data collectors

www.DowntimeCentral.com


Digging for data
Digging for data

  • equipment histories,

  • CMMS reports,

  • life cycle cost analyses,

  • financial records,

  • production schedules.

These are the recommended sources to build a cost justification report to be presented to the bean counters.

A maintenance manager would need a full time research assistant to run a productive department.


Measurement effectiveness
Measurement effectiveness:

  • Do measures such as maintenance cost / RAV show contribution to real objectives?

    • age of equipment, process intensity

  • MTBF; total population / total repairs or equipment specific statistics

    • which, what, how often

  • PM compliance and PM backlog, % overtime, % PM compared to % reactive

    • don’t measure whether activity is required or how much value is produced

www.DowntimeCentral.com


What do all these data sources have in common
What do all these data sources have in common?

  • They all build on downtime cost estimates that are only 10% or less of the True Downtime Cost. (10%TDC)

  • Cost justification requires analysis of several of these areas by management.

  • Often you have to justify the validity of the data source.

www.DowntimeCentral.com


Where does valid data come from
Where does valid data come from?

  • all computer systems and networks

  • plant automation systems

    • distributed control systems

    • programmable logic controllers

    • diagnostic monitoring systems.

  • asset management software

How to bring it all together
How to bring it all together

  • Wonderware

  • Versacall

The new millennium focus is on bringing the valid data from various sources back to the management software and technique of your choice.

Will this full circle of data management bring us close to 100% management efficiency?

www.DowntimeCentral.com


Versacall com

  • VersaCall Facility Communications System.

    • capture and document  downtime

    • monitoring response time

    • communicating an alarm occurrence

"5% of cost in a sites production capability from downtime is a fairly safe number. It does vary by industry ~ mostly going up from the 5%." 

"80% of the manufacturing operations I have interacted with have no idea what they are losing in true dollars with downtime."

www.DowntimeCentral.com


Not even close

  • You will see a 200% to 300% increase in efficiency, but that’s only 30%TDC, will that give you the required ROI?

  • Why settle for 300% when you can easily have 800%?

The answer tdc
The Answer, TDC

  • Actually a combination of two methods are used to bridge the gap between data collection and management technique.

    • Strict usage of TDC metrics

    • And data sharing standards like MIMOSA

Mtbf example
MTBF Example

  • Average 2 year MTBF on 2,000 pumps (compared to world class -- 6 to 7 year)

  • Average cost of repair $5,000

  • Double MTBF to 4 years

    • saves $2.5 million!!

  • 6 year MTBF

    • saves $3.3 million

  • That’s at the profit level!!

    • how much product must be produced to deliver $2.5 million profit at 10% pretax??

  • PROFIT CENTERED MENTALITY

Tdc warning data overload

Overhead

TDC-Warning Data Overload!

Too many variables, Too complicated, Too much change!

Equipment

These are all one time entry of constants, updated annually, exported from your existing computer systems.

&

Labor

These are per downtime occurrence entries, but most can be exported from your CMMS.

Downtime

You can use a percentage of existing numbers depending on amount of TDC metrics they are made up of

www.DowntimeCentral.com


Is using tdc too much change
Is using TDC too much change ?

Not really. You just need to require up front that your vendors adhere to MIMOSA standards and TDC metrics.

Your vendors being data collection equipment vendors, and software vendors such as CMMS.
