Embodiment Construction

[0062] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0063] Such as figure 1 As shown, an optimized procurement and boat / vehicle transportation method based on artificial immune algorithm includes the following steps. S1: Obtain data related to goods procurement and transportation requirements; S2: Set the chromosome coding method of antibody goods procurement and transportation plans, and set chro...

Abstract

The invention relates to an artificial immune algorithm-based cargo purchase and ship / vehicle sharing transportation scheme optimization method. The method comprises the following steps of S1: obtaining cargo purchase and transportation demand related data; S2: setting a chromosome coding method for a cargo purchase and transportation scheme of antibodies, and setting chromogene information; S3: setting algorithm parameters; S4: identifying antigens, and taking given target functions and constraint conditions as the antigens; S5: generating an initial antibody population, and randomly initializing the antibody population in a solution space; S6: interpreting the chromogene information of all the antibodies in the antibody population, generating a purchase-ship / vehicle sharing transportation and distribution scheme, and calculating affinity, antibody concentration and stimulation degrees; S7: cloning part of the antibodies with relatively high stimulation degrees to form a temporary antibody population; S8: generating new antibodies through methods of gene mutation and the like in the temporary antibody population; S9: selecting excellent new antibodies from the temporary antibody population to replace relatively poor individuals in the antibody population so as to form a next-generation antibody population; and S10: judging whether an ending condition is met or not, and if yes, stopping calculation and outputting a ship sharing purchase-transportation scheme, otherwise, going to the step S6 for continuing to carry out the process.

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...
