The invention relates to a goods procurement and ship/car-pooling transportation method based on a particle swarm algorithm. The method comprises the steps that S1, goods procurement and transportation demand relevant data is acquired; S2, a chromosome encoding scheme for goods procurement and transportation of individuals in a particle swarm is set, and chromogene information is set; S3, particle swarm algorithm parameters are configured; S4, an initial particle swarm is generated randomly, including a position swarm and a speed swarm; S5, the chromogene information of all the individuals in the particle swarm is read, a procurement-ship/car-pooling transportation delivery scheme is generated, and adaptive values of the individuals in the particle swarm are calculated; S6, an individual historical optimal scheme and a swarm historical optimal scheme are recorded, and speeds and positions of all the particle individuals in the swarm are updated; and S7, whether a termination condition is met is judged, if not, the step S5 is returned to, circulation is made in this way till the termination condition is met, and if yes, optimization is ended, and an optimal scheme is output.
