[GRASS-user] Suggestion for creating a script to create a map of agricultural capacity

I'm working on the preparation of the statement of Agricultural Capacity in
general terms the *final map* has classes ranging 1-8.
To get this map I use three themes with their respective notes:
- Map of Slope: with classes ranging 1 to 8;
- Soil Map: with classes ranging 1 to 8;
- Map of flood risk: with classes ranging 1 to 8;
I - After converting all to a vector format and "merge" the three layers, I
have multiple polygons with various combinations, eg:
II - To determine the final value of the class is chosen the highest value:
I need to automate this task because the last step (II) is very slow
(actually manually), which would be the best way to do this? I think the
whole process can be done with the data in raster format, but have not
found a formula that I can apply in r.mapcalc to this problem.
Thanks in advance,
