L.S.,

can anyone tell me whether there are any constraint approaches to route
organization for letter carriers? 
(The problem is, to devise routes for postal employees which deliver the mail.
These routes are subject to various constraints, i.e., workload constraints,
capacity constraints, geographical constraints (one cannot cross a highway on
foot very easily), etcetera.
I am looking for (commercial) packages aimed at this particular type of
application. 
I am aware of more general packages, like ILOG SOLVER, etcetera. 

Any help will be appreciated. With kind regards,

Gidi van Liempd
