Not sure if understanding clearly you query. Are you referring to simulation models for agroforestry systems? If so, I suggest you the simulation models HiSAFE, YieldSAFE and FarmSAFE, for biophysical and financial modelling of temperate AFS. All of them were developed into the European Project SAFE (2001-2005), and currently implemented in the ongoing project AGFORWARD (2014-17)
