Correct me if I'm wrong, haven't written a lot of Prolog, but I think most optimisation-based problems are suitable for modelling using Prolog. Scheduling, time tabling, allocation problems such as knapsack problem or bin packing, etc.

Some of these problems can be quite tricky to write regular code for, but just stating the constraints and letting Prolog plan/solve it can be simpler.
