The present invention relates to a method for optimizing cargo procurement and ship-sharing / vehicle transportation plans based on an artificial immune algorithm, which includes the following steps: S1: Obtaining data related to cargo procurement and transportation requirements; S2: Setting the antibody's cargo procurement and transportation plan. Chromosome encoding method, setting chromosome gene information; S3: setting algorithm parameters. S4: Antigen recognition, using the given objective function and constraint conditions as the antigen; S5: Generate an initial antibody group, and randomly initialize the antibody group in the solution space; S6: Interpret the chromosome gene information of all antibodies in the antibody group, and generate a procurement-combination Ship / car transportation and distribution plan, and calculate the affinity, antibody concentration and excitation degree; S7: Cloning some of the antibodies with higher excitation to form a temporary antibody group; S8: Generating new antibodies in the temporary antibody group through gene mutation and other methods; S9: Select excellent new antibodies from the temporary antibody group to replace poor individuals in the antibody group to form the next generation of antibody groups; S10: Determine whether the end conditions are met, if so, stop the calculation and output the ship-sharing procurement-transportation plan; if No, go to step S6 to continue.
Description
technical field [0001] The invention relates to the technical field of optimization and intelligent computing, in particular to a method for goods procurement and boat / vehicle transportation based on an artificial immune algorithm. Background technique [0002] For a group-operated company, the resource procurement needs of each branch are often scattered, and each resource procurement and transportation requires a relatively high logistics cost. Collecting the procurement needs of each branch and formulating the alliance procurement and assembly transportation plan by the headquarters through an optimization method can often obtain higher economic benefits. [0003] The unit cargo transportation cost of large ships (vehicles) is generally much lower than that of small ships. For multiple batches of scattered goods with similar supply and demand and long midway transportation distances, assembling different batches of scattered goods into large ships (vehicles) for transpor...
