The Transportation Manager for AM&L Northeast Region supports a network of five customers on a daily basis. The customers are supported through the use of two delivery trucks. AM&L employs the Savings approach in the Northeast Region. The Transportation Manager wants to determine the routes the trucks will take, which stops should be made on the routes, and which sequence the stops should be served by the route trucks. How should the truck tours be sequences as to minimize total ton miles? You must show savings calculation to receive credit!

For example, let's assume the pairs having the greatest savings were AB, CD, and EF (don't use these for your solution!). The possible combinations would be: ABCD, ABEF, CDEF When determining the combined distance, you should first circle the four points on the above diagram. You should then apply the heuristics of no crossed paths and a "tear drop shape. Simply start at the DC and then draw a "loop" through the points that returns to the DC. You can start with any of the four points. If you take this approach, then you will select the order that produces the most savings. If your route crosses paths, doubles back, or does something that increases miles, then you will not obtain the most savings and will most likely lose points!
