The real dataset has 6772 customers that distribute in the centre and suburb of the Suizhou city. We
partition the whole customers into 5 areas accordingly to the real requirement.
Figure 5 shows the portioned five areas in Suizhou city, which is a real dataset with large number of
customers. Figure 6-10 are the constructed routes by NNS + INTRA- & CROSS-EXCHANGE for five
areas, respectively. The new approach takes a good effect in the real application, which greatly reduces the
total distance for routes. Therefore, it decreases the costs and improves the efficiency for the tobacco
delivery.
