Research On The Dynamic Distribution Of Agricultural Products In Short Chains

With the increasingly complex logistics and transportation business,the society has higher and higher requirements for transportation efficiency and cost.During the distribution process,the increase and decrease of customer orders have become the norm in logistics and distribution.In particular,healthy agricultural products have become a commodity sought after by urban residents,and the distribution of agricultural products has gradually entered the public eye,but the low transportation efficiency and high cost of agricultural products have become important factors restricting the development of agriculture.The proposal of the short-chain distribution mode of agricultural products provides a breakthrough for solving this problem,and has gradually become a new logistics distribution trend.First of all,starting from the distribution background of agricultural products,this paper deeply investigates the research status and achievements at home and abroad,and adopts the "short-chain distribution" model to greatly improve the efficiency of logistics and transportation.Secondly,this paper assumes that all agricultural products have been collected in the rural distribution center,and considers the short-chain distribution and pickup process from the agricultural distribution center to each supermarket user,and adopts a collaborative open parking strategy.By improving the genetic algorithm,optimizing the value of the objective function of penalty cost,distribution cost and start-up cost,the distribution of static customer orders is realized;for dynamic customers that appear in the distribution process,the minimum insertion algorithm is adopted under the premise of considering the vehicle load.,inserting the dynamic order into the original distribution route for distribution with the minimum insertion cost,which improves the efficiency of vehicle use.Finally,through the examples generated by simulation,this paper uses the improved and traditional genetic algorithms to solve the problem,which proves the efficiency of the improved genetic algorithm;for dynamic customers,the minimum insertion method is used to solve the problem,and the dynamic customers are inserted into the original distribution route;The process of visual analysis is carried out,and the process of vehicle distribution of agricultural products in this paper is simulated on the PC,which can directly observe the problems that may occur in the process of short-chain distribution of agricultural products in real time,which can help improve the actual distribution efficiency of agricultural products.
