Research on a kind of improved network transport model and its application in logistics industry

Abstract

Logistics industry is becoming a more and more important field needed to be concentrated for all kinds of enterprises to reduce their own operation cost, and shorten their delivery time and so on. How to change the complicated logistics problem into abstract network model is elucidated here. Firstly, a directed graph G = (V, E) is used to describe the general logistics problem with some common restrictions such as cost and time etc. Secondly, considering the growth of logistics node, an improved network transport model was set forth. Thirdly, the combination of ant colony arithmetic with logistics network transport model is expounded, based on the similarity between logistics network transport model and Travelling Salesman Problem. Finally, the solution and analysis for the improved model is illustrated according to the ant colony arithmetic, and some related conclusions are detailed.
