1) By lack of preplanning capability which is overcome using an offline
process, Do you mean an hybrid approach combining on-line and off-line
routing? If so, how is such routing model implemented? 

2) do you (or someone else) know the difference between these two
approaches besides the performance  parameter.

Thanks in advance
