From a Bachelors thesis:
In this simple transportation model I see at least two problems.
The capacity constraint should probably look like:
| forall (o in DCs) ctCapacity: sum(p in Products, d in Stores) Trans[p][o][d] <= Capacity[o]; |
The care needed to write correct models is often underestimated.
Just because I want to understand more. The top one is simply because they doubled the transportation cost, when they were trying to do transportation between 2 locations instead?
ReplyDeleteWould this be not more obvious:
ReplyDeleteTrans_Cost[p][o][p]+DC_Cost[p][o][d]
ahhhhh. yeah, that makes sense.
