The previous times I ran the model with the same data it took me 2-3 hours, but this time it was over seven hours. I thought it was strange. I have uploaded the file of model operation process, I hope you can help me solve it, thank you very much!

Hi @JCJC , looking at this logfile in isolation, no problems are evident. The model runtime is largely dependent on the size and resolution of the input rasters and the “threat distance” parameters.

_Something_ must have changed between this run and the others, even if it wasn’t your data.
