Model with Varying Costs |
INDEX PREVIOUS NEXT |
With this additional consideration about costs varying according to quantity, our model now looks like this:
minimize
subject to
yij =
(xij) for
i = 0, ..., nbDemand-1 and j = 0, ..., nbSupply-1
With this problem in mind, consider how to represent the data and model in Concert Technology.
