Asset Utilization

[Former Member]

Hi every body.

I would like to picture out the Asset Utilization of a Production Units

Please can some one explain to me EXACTLY :

- what is Asset Utilization?

- Which data do i need to animated a SVG who´s represent the Asset Utilization?

- what would be the procedure?

- Can i also use a Chart to do that?

Thanks

Hi,

Asset utilization is defined as a measure of the degree to which an asset, such as plant production line is being employed in a profitable activity.

AU = Availability * Duty cycle * Efficiency* Yield

For further assistance, please refer

Hi Emile,

I think by now you should have understood what is Asset Utilization.

Second part is showing the value of the Utilization on SVG :

1.Initially you need to select a animation object which suits for your purpose in animation editor. If not avialable you can create your own animation object in Inkscape.

2. After that create four object properties for that object in animation object editor.

(For your case they are inputs for the calculation like Yield, Availability....)

3. Next create a Calculated property in terms of these object properties. (Multiplication of all the inputs in your case)

4. Then in Animation links you need to link this calculated value of the Asset Utilization with vector graphics. Here this expression involves geometric equation which depends on the type of graphic.

Ex : If it is a temperature bar then you need to calibrate the value with the length of the thermometer.

If it is a circular gauge you need to write the expression to calibrate 0 to 100 % into 30 degrees to 270 degrees in the circular scale.

After completion of this Step you need to go to Business Logic Editor to map the inputs for the animation object. In BLS you need to pass the input values for th display (Yield, Availability..) to this animation object and map them with the variables you created in the Dynamic Graphics editor.

After execution it save that image in a location in server and call that image in your page.

Suppose if you want to show the value in a gauge you need to pass the input parameters in a transaction and create a dyanmic table with this output and pass it in a Xacute query to a display template in your Applet.

But i can suggest you to use SVG because of their rich look, it gives better impression also. Even you can add more parameter in your display other that value indication.

I hope this explanation helps you. If you need any help please let me know.

Thanks Rajesh.

U´r response was the best.

I think my Problem would be solve soon.

But if u can provide me more Infos about the TAU Components, i mean Availability,Duty Cycle,Efficiency and Yied.Just take the Exemple whith One Produktion Line so i can see exactly which Tags i need.The Procedure was ok.

I forgot some thing.

There is any difference between AU and TAU?

Hi Emile,

The following are the answers i knew. But you need to verify these things with the shop floor experts. One more thing for your case the time frame for these parameter calculation depends on the requirement of the data. Is the index is for one sigle day or for one month or total production like...

1.Availability : If you are SAP Plant Maintenance is configured well, you can calculate the availability from the Breakdown and Predictive maintenance information.

2. Yield : For this you should know the production details and throughput of your equipment. Then you can calculate the percentage of the difference between your production and throughput of your equipment.

3.Efficiency : For this what is your exact defenition, you need to contact your SCM or manufacturing experts of your case.

4.Duty cycle : Ratio between the on and off time of the equipment.

And finally i dont know what is AU and TAU components.

I hope this answer helps you. But in this case i have very less info on the theoretical terms.

Thanks,

Rajesh.

PS : Award points if you find answer useful.

Hello Rajesh,

AU : Asset Utilization

TAU : Total Asset Utilization

Thanks

Hi Emile,

Check out these links for AU and TAU.

Hi Emile,

I can explain what is exxactly Asset utilization and Total Asset Utilization.

Generally in many scenarios for the shop floor application the main overview page will contain the display of the TAU, because it will give the total plant health index. In that case suppose if there are five or six equipments in a plant you can take the average values of the input params and you can calculate the TAU. Where if the production manager or shop floor incharge wants the detailed information about the plant then by clicking on the image of the TAU, he should be navigated to the Asset Utilization page. Then you can show the index of the each equipment individual asset utilizations.

But in development scenarios the time considerations of the calculations should be decided by the user. Generally for Overview page it is the whole day. And in detail it is in daily/hourly.

I hope this explanation will help you.

Thanks,

Rajesh.

PS : Please award point if the answer is useful.

hi

pls help me to solve asset utilization

scenario:

there are 3 types of assets(laptops/desktops/servers)

there r 3 shifts

i need to infn from swipe card

i should calc asset utilization

will u pls explain me the procedure

i know gp n webdynpro

thank u

vani,

this should be a new thread and i don't understand your shorthand, please repost in complete words. thanks.

- what is Asset Utilization?

see above

- Which data do i need to animated a SVG who´s

represent the Asset Utilization?

You need to bind the calculated value to your svg variable set for drawing the angle of your scalepoint.

typically this variable is called 'value' in the standard xMii svg gauges.

- what would be the procedure?

Calculation of asset utilisation and binding it to the svg image is typically done in the business logic editor.

- Can i also use a Chart to do that?

You can use a standard xMii chart applet in gauge mode ( scale from 0 to 100 %)

In that case you calculate the value and bind this to the output variable of a BLS transaction. You then bind this transaction to the query part of your applet.

Vincent
