I'm looking to create raster layers from vector layers, rescale them, weight them then finally combine them for a final result.

I'm really not sure about the process to do this. On Arcmap it's really straight forward but on QGIS I'm having significant difficulty. This is the process I use on arcmap: Vecter layer --> Eclidean Distance --> Rescale new layer using min-max score transformation on raster calculate --> combine all raster layers with Weighted Sum Tool.

I can't for the life of me figure out the same process in QGIS.
