The invention discloses a logistic distribution method based on a cloud computing platform, which applies an ant colony optimization algorithm to logistic distribution path planning, realizes parallelization processing of the ant colony optimization algorithm based on the hadoop cloud computing platform, and realizes large-scale logistic distribution. According to the method, the ant colony optimization algorithm is realized by an HDFS (Hadoop Distributed File System) of the hadoop platform and a MapReduce parallel programming frame, the ant colony optimization algorithm is parallelized by MapReduce, each iteration time is accelerated, the HDFS is used for storing parameters and intermediate files, the parameter read and update rate of the ant colony optimization algorithm is increased due to the high efficiency and high reliability of the HDFS, and a path search progress is accelerated.
