(MCVRP)Multiple compartment with different capacity in a single van.

[SruthyJohn]

Hi All,
I am modelling a CVRPTW problem, and able to successfully get the solutions for various constraints.

But for some vehicles, there will be multiple compartments( with different capacities) - as an example, Chiller compartment, Dry compartment to carry chilled products(A) and dry products(B). These products should not be mixed, and also a node/retailer might need a delivery for A_, AB, _B (chilled product only, mixed order with chilled and dry, dry product only).

How can we handle this?
