Thank you for your answer. May I ask you the following questions. Thanks for your help. Wish you a good day. a) In https://biosteam.readthedocs.io/en/latest/API/evaluation/Model.html#biosteam.evaluation.Model.get_distribution_summary:~:text=kind%20(%7B%27coupled%27%2C%20%27isolated%27%2C%20%27design%27%2C%20%27cost%27%7D%2C%20optional)%20%E2%80%93, when do we choose b) For c) When do we use d) If it only affects the mass balance and energy balance, but does not affect the design, is the kind chosen as coupled? e) If I am not sure whether it will affect the design, mass balance and energy balance, is it better to use coupled than design and isolated? f) For the top questions 3, 4, 5and 6, could I trouble you to look at them? |

a. When the parameter only affects price (i.e., not mass/energy flow). |

Oh I see, perfect, thanks for the note!

For parameters, kind='cost' and kind='design' are the same. Regardless if
you pass 'cost' or 'design', both the design and cost algorithms are rerun
when the parameter is simulated. Long ago, they meant different things, but
the decision was made to simplify it. I will update the documentation to
note that 'design' and 'cost' mean the same thing and both options are kept
for backwards compatibility.
*Update*
@yalinli2 <https://github.com/yalinli2> , sorry I forgot to update you
regarding this change:
When running <Model>.evaluate() the system *always* simulates completely
regardless of what kinds of parameters it has ('coupled', 'isolated', or
'design'; it does not matter).
The only time the choice of 'coupled', 'isolated', vs. 'design' comes into
play is when:
- Setting a parameter directly. For example, <Parameter>(value), just
like in the documentation (
https://biosteam.readthedocs.io/en/latest/tutorial/Uncertainty_and_sensitivity.html#Add-cost-parameters
).
- When using a convergence_model, which is entirely optional (
https://biosteam.readthedocs.io/en/latest/tutorial/Uncertainty_and_sensitivity.html#Monte-Carlo
).
I will update the documentation to make this more clear later today.
@zasddsgg <https://github.com/zasddsgg>, for your purposes, don't worry
about the kind argument... there is no need to pass any value.

Hello, could I ask you some questions about kind setting in uncertainty analysis in BioSTEAM. Thanks for your help. Wish you a good day.
Are the design, coupled and isolated parameters in https://biosteam.readthedocs.io/en/latest/API/evaluation/Parameter.html#:~:text=kind%20(str,in%20any%20way the same as the decision variables, technology parameters, and contextual parameters in the article “BioSTEAM-LCA: An Integrated Modeling Framework for Agile Life Cycle Assessment of Biorefineries under Uncertainty”?
In lactic acid models.py (https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/lactic/models.py#L303-L309), solids loading will not only affect the mass and energy balance of the process, but also the unit design, why
kindiscoupledinstead ofdesign?The different loads (Pretreatment solids loading, Pretreatment sulfuric acid loading, Enzymatic hydrolysis solids loading, Enzyme loading) (https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/lactic/models.py#L304-L316, https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/lactic/models.py#L331-L343), the
kindare set tocoupled, but how does the different loads (Pretreatment solids loading, Pretreatment sulfuric acid loading, Enzymatic hydrolysis solids loading, Enzyme loading) affect the mass and energy balance of the process, including the yield?For
@param(name='Enzymatic hydrolysis time')(https://github.com/BioSTEAMDevelopmentGroup/Bioindustrial-Park/blob/master/biorefineries/lactic/models.py#L347), why kind is'coupled'? Shouldn't theenzymatic hydrolysis timeonly affect the unit design, how does it affect the energy balance and mass balance?How do

It seems that they only affect the unit design, so should thekindbedesign?Which
