Abstract： In order to enhance the efficiency of cold chain distribution for vegetables and fruits and lower the cost， according to TSP theory， the distribution network optimization model should be established with the shortest path and minimum cost as the goal， and the liner programming should be used to solve it combined with the case of fruit and vegetable transportation.  The consequence shows that after optimization， both the distance and transport cost decreased obviously， which could better meet the requirements of distribution service in the market.

Key words： transport of vegetables and fruits; TSP theory; programming solver
