The above table can be explained, in the following approach

(1)35 bbl from Kingport, to the Whitewater waste disposal herb. (2)1 bbl from Selma to the Whitewater waste disposal herb. (3)29 bbl from Columbus to the Whitewater waste disposal flower. (4)52 bbl from Selma to Los Canos waste disposal plant.

(5)28 bbl by Allentown to Los Canos waste disposal herb. (6)26 bbl from Danville to the Duras waste disposal plant.

(7)42 bbl from Macon to the Duras waste disposal herb.

(8)10 bbl from Allentown to the Duras waste disposal herb.

3. Revised Problem Using Intermediate Sites

A closer glance at the problem shows that, there are particular other beginnings exists inside the model and using these types of roots along with some more advanced positions during these roots to drop the waste and then indexed to the desired location will reduce transportation expense, instead of transportation them right to a garbage disposal centre. Therefore dropping the waste in certain intermediate position while described under will give substantial cost benefit to the delivery company. Thus by considering all this sort of possibilities a few intermediate places are found shed the spend to minimize travel costs. All such root base with the lowest cost are given in bold notification in the pursuing table.
