> Hello,
> I'm looking for references regarding the above problem, where a set of
> customers (retail stores belonging to the same company) is to be serviced by
> an heterogeneous fleet of vehicles (fixed container, removable container,
> semi-trailer...). The orders are splitted since:
> 1) orders sometimes exceed the vehicle capacity
> 2) Some products need to be shipped at least for a given amount in narrow time
> windows (for example, bakery products in the morning before shop opening, then
> in the afternoon)
> 3) some stores cannot accomodate their total order at once, because of
> limited storage space. (the size of shops varies in a wide range from very
> small local outlets to malls)
> 
> Finally, shipments are often mixed, especially in the morning, when shops need
> to be fully reassorted. The company owns 60 vehicles, ?trailers and approx. 55
