Extensions
1) Fixed constraint on the number of vehicles available
In the model that has been implemented to solve the pizza distribution problem, it is assumed that the number of vehicles will be determined freely in the course of determining the optimal solution, in this case three. One extension to this problem might occur if it was decided that there was some upper or lower bound on the number of vehicles available for pizza delivery. In this case, if it was decided that only two delivery vehicles were available it is clear that the optimal solution to the transshipment problem would change, as the present optimal solution includes three transportation vehicles.
2) Fixed constraint on the size of the oven in Pedro's Pizza
In our model, each driver can carry a maximum of four pizzas. However if a customer orders more than four pizzas, then our model would not be able to handle this. An extension for our current model would be to allow a delivery person to wait until all the pizzas are made before going out for delivery.
3) The driver does not return to Pedro's Pizza.
Currently our model does not handle the cost for the driver to return to Pedro's Pizza once he has completed his delivery. One extension would then be to allow the driver to return to Pedro's Pizza and pick-up more pizzas to be delivered.
