I have a large area divided into three parts. Each of these parts is divided into smaller parts. Each part contains an amount of biomass that can be cut and sold. The total amount of biomass in the entire territory is about 1,170,000 m3. This quantity should be realized in 10 years. Approximately 117,000 m3 (+/-1000m3) should be cut every year, which would amount to 1,170,000m3 of biomass in 10 years.
I tried to do it with the "Attribute based clustering" Plugin, but I couldn't get nearly equal parts.

Is it possible to do something like this using QGIS?
