Abstract: Grain logistics nodes are an important part of the support of the grain logistics system. Using a reasonable method to determine the level of grain logistics node cities is the key to scientifically deploy grain logistics nodes. With the formation of the grain circulation pattern of “transportation of grains from the north to the south” and “transportation of foreign grains to the inside”, it is of great significance to optimize the layout of grain logistics nodes in the “coastal channel”. Based on the related research of grain logistics node layout, we build the primary index of index system which includes the logistics demand, service capacity, transport facilities, food industry economy and logistics node importance, adopt the entropy weight method to get the index weight of grain logistics nodes, calculate the grain logistics nodes development index of the coastal channel, and provide policy suggestions to optimize the of grain logistics channel distribution.
Key words: grain logistics; node optimization; planning and layout; coastal channel; entropy weight method
