Research On Optimization Of Road Transportation Costs In Logistics Enterprises Based On LP

The logistics industry of our country develops backward, the cost of logistics is far higher than America, Europe and Japan. And the transportation cost of it occupies a fairly large proportion. Our country invests tens of billions to the traffic infrastructure construction in 2009, which broad improves the highway grade of our country and promotes some cities'road network optimization. And that will reduce the transport cost of the logistics of our country. This paper qualitative analysis the road grade's influence on transporting cost, and analysis the Urban Road System overall arrangement's influence on transport cost.The paper selects to research on the road transportation costs of logistics enterprises, attempting to optimize the costs. We analyze the relation between the road costs and the distance and draw a conclusion, which is that the transportation costs increase along with the shipping weight, but unit transportation cost is opposite with it; the transportation costs increase along with the transportation distance, but unit transportation cost is opposite with it. Based on this, we get the optimization plans of transit route links to the current reality of China's logistics enterprises. Finally, in view of the situation of the supply and demand balance,supply and demand imbalance,with transit stations an so on, which are the impact of transportation costs, we introduce the theory of linear programming to plan the route of transport operations, trying to find the lowest cost solution of completing the mission. In considering the price of different transport routes of different premise, through different routes, different choice of volume, making the lowest cost of transportation logistics. The research on the logistics model of transport costs ensures the most reasonable transportation costs.
