A few suggestions for a further improvement

Hi there,


first I want to thank you for developing STAN. I'm currently using it for my master's thesis. I have a few suggestions to improve STAN (and will edit this post if anthing particular shows up):

- Add a last opened files bar or a pop up with your last opened files like it is in word, e.g.

- Add the option to separate the different layers so that you can get one layer for your goods with all their in- and outputs and when you select the layer energy all processes remain but only the energy related in- and outputs show up.
// It gets a bit messy if you are trying to modell a production chain with various in- and outputs and then having to add the different fuel, energy and steam flows. My work-around was to copy the whole process, delete all in- and outputs and place new ones but I would prefer an integrated solution that is able to sum it up in the end. Or is there a solution I didn't came up with?

- Add an option to let STAN calculate the carbon dioxide outputs of the different processes conected to the formulas or parameters you add to each process. e.g. the high pressure forming of a tire generates like 12.34 g*CO2/tire
// Or is there a possibility yet? My current work-around is to set an CO2e output to every manufactoring process and reunite them in another process to get the total amount. I would be thankful for any kind of advice.


Thanks so far,


Georg Meinecke


//btw: is there a way to count stuff like transmission losses regarding energy?

Hi Georg,

Thanks for your remarks.

In STAN you have the option to hide flows with value zero. All you have to do is go to "Extras" > "Options" > Tab "Processes and Flows" and tick "Hide flows with average value zero". If you now assign zero energy values to any flows that you don't want to display on the layer of energy they will be hidden.

The other questions are difficult to answer without seeing your model. If you upload your file to the webserver I will have a look on it.

Regards,
Oliver

Hi Oliver,

thanks for your answer.

Unfortunately I can't upload my model because it contains sensitive data of the company I'm writing my master's thesis at.

My problem was that I tried to get STAN to calculate everything for only 1 piece produced and afterwards a scalable option for sth like 1h = x pieces = x CO2. I skiped that attempt because I didn't find a option to give each process a processing time exept for messing around with the unit scales a lot. I basically switched to fitting the right values all the inputs, connections and outputs to generate a good looking sankey diagram for a better visualisation and did all the calculations through excel.

My deadline is close and now I know how to hide empty flows. No more time for changes anyways. I just wanted to give you an reply.

Greetings,

Georg
