Can I define the system boundary by deleting some processes manually in the "graph model" tab ?

Question

Hello,

The ecoinvent database automatically considers too many upstream and downstream processes which I do not want them.

Can I define the boundary of the system by manually modify the model graph when I create the product system? For example deleting a process which I do not want to be included in my model.

Hi - "too many" is maybe somewhat subjective, but to your question: yes you can of course set the system boundary by modifying the model graph, i.e. deleting processes or supply chain branches in the model graph, and if you start from the full system created via autoconnect, you can reduce the system size and the nuimber of upstream supply chain branches.

Best wishes,
