I can tell you how you would do this problem in principle, but I'm going to suggest that you may run into some difficulties (if you already know everything I'm about to say, just take it as advice to the next reader ...)

• theoretically, the Galton-Watson process extinction probability never goes exactly to 1 (unless prob==1, or in the infinite-time limit)
• of course, for any given replicate and random-number seed you can compute the first time point (if any) at which all of your lineages have gone extinct. This will be highly variable across runs, depending on the random-number seed ...
• the distribution of extinction times is extremely skewed; lineages that don't go extinct immediately will last a loooong time ...

I modified your GWP function in two ways to make it more efficient: (1) stop the simulation when the lineage goes extinct; (2) replace the sum of geometric deviates with a single negative binomial deviate (see here)

An Android 11 device is required: source

GWP-ASan is only available on Android 11 devices. So - for an app to have GWP-ASan, you need: (1) A device with Android 11, (2) android:gwpAsanMode="always" specified in your manifest. Additionally, you'll need to build your app using the Android 11 SDK, as the flag in (2) isn't defined in older SDKs and will fail to build.

When you used input$select, it is a string (input$select = "CLIENT_TYPE").

So you need to use the function group_by_() (or group_by_at()) instead of the function group_by(). This function will understand that the string should be consider as a variable of the data.frame.

More information here: dplyr: whats the difference between group_by and group_by_ functions?

The main problem here is the fact that you are trying to open a text variable as a file:

I found that this works for the first part:

you can access dictionary entries with their keys e.g.

If you mean "does Brightway2 scale exchanges based on the 'units' attribute", the answer is no.

Like almost everything else in Brightway2, this is not impossible. However, units are not part of the processed data stored by Brightway (i.e. it is not part of the stored structured arrays from which the MatrixBuilders build the A and B matrices).

See here and here for more info in processed data and building matrices.

Parameterized inventories generally don't work in Monte Carlo, as the Monte Carlo class is focused on data point uncertainties described by PDFs. There is a separate project called presamples which allows for the use of parameterized inventories in Monte Carlo through some pre-calculations - however, it doesn't have great documentation yet. Look in the docs, and ParameterizedBrightwayModel.

Note: Check your parameter names and formulas from SimaPro, Brightway is stricter in what it allows (e.g. python is case sensitive and has more reserved words).

Variables in script behave differently than they do on the expression side. In the script they are more like "replace this variable by the current value" than an actual variable evaluation.

That said, don't use the equal signs (not needed) and make sure that all variables that are not numeric are enclosed in '. For instance :
