| With the rapid development of economy,people have higher requirements for their own quality of life,especially in food quality.More and more consumers hope to transport fresh agricultural products from the field to the table,which brings a lot of challenges to cold chain logistics enterprises.Compared with ordinary products,agricultural products are perishable,so how to deliver these products to customers with high quality and quantity is very important for the development of enterprises.Reasonable arrangement of the driving route of vehicles can not only improve the distribution efficiency of agricultural products,but also achieve the purpose of reducing cost and increasing efficiency and improving customer satisfaction.This paper took M company as the object,aiming at the problem of agricultural product supply path planning.First of all,taking M company as the background,this paper expounded the significance of optimizing the driving route of vehicles for the development of M company,and analyzed the current situation and shortcomings of domestic and foreign scholars on the vehicle route problem Secondly,the paper analyzed the present situation and existing problems of agricultural products distribution in M company,and found that the distribution path planning of agricultural products in M company was relatively random,mainly based on the subjective experience of drivers,and lack of scientific guidance.Thirdly,according to the real supply condition of M company,the paper analyzed the composition of distribution cost and related constraints,and established a path optimization model based on time window constraints and taking the minimum distribution cost as the objective function.At the same time,the genetic algorithm was taken as solve the model,and the genetic operators were regard as increase the diversity of the population and avert premature convergence and local majorization.Finally,the simulation analysis was carried out with MATLAB software,and the optimized distribution route scheme was compared with the actual distribution route scheme of M company,which proved the effectiveness and practicability of the model and the improved algorithm. |
