Multi inputs
#1
Dear all,
     In the demo models, the way to model multi inputs is to use Share~I~UP with the same units. Now I want to model multi  inputs for one output, is there some way in addition to Share~I~UP(because the units of inputs are not identical)?
    Thank you very much.

If the units are not identical then the inputs are likely not fit to be in the same commodity group. See if you can use the INPUT attribute instead.

I working with the Fuel Mixes a lot where a total energy input is in PJ and let´s say there are 4 different fuels input (NG-2 PJ, ANT-1 PJ, HFO-1 PJ, BIO-1 PJ) all these fuel transform via proces to NRG - FMIX01 commodity but some boilers needs additive like limestone in Mt - (million tonnes) In this case i m using INPUT together with SHARE-I or Auxiliary Input for Material input.

    Thanks for your reply. In the demo, I find that one output(Mt) with five inputs(one of them is Mt, and rest of them is PJ), is it correct? Please see the attachhment.
    Thank you very much.

Yes, there´s nothing wrong Smile

Yes, I cannot see anything wrong there either.

But using Input is good only when the input share should be fully fixed. If you would like to model flexible shares among the energy inputs, you could use ACT_EFF(r,y,p,'NRG',ts), plus some FLO_SHAR where needed.

You can also use FLO_SHAR between a material and energy commodity, if needed, or between a material commodity and the whole group of energy inputs, or even between a material commodity and the process activity.
