Embodiment 2

[0099] When considering the solution of the route optimization problem, the present invention adopts genetic algorithm. The genetic algorithm is an algorithm that simulates the theory of biological evolution proposed by the famous biologist Darwin. In Darwin's theory of evolution, nature will test creatures according to the living environment in nature, leaving individuals with high-quality genes and suitable for survival. The fitness of the genetic algorithm is equivalent to searching for individuals in nature by setting rules and adopting the method of survival of the fittest. Individuals who adapt to the environment will have a greater chance of survival and produce offspring. Its characteristic is that it can retain potential deconstructed genes in the inheritance, and then realize the global search. Genetic algorithm is very suitable for multi-objective function optimization and nonlinear combinatorial optimization problems because of its low requirements on mathematics, ...

Abstract

The invention discloses a method for optimizing a sea-railway combined transportation route in a Chinese-European land-sea fast line. The method comprises the following steps: S1, constructing a transportation network of the sea-railway combined transportation route in the Chinese-European land-sea fast line; s2, according to the transportation network of the middle-sea-railway combined transportation route of the Chinese-European land-sea fast line in the step S1, constructing a model for optimizing the sea-railway combined transportation route of the Chinese-European land-sea fast line; and S3, solving the optimization model in the step S2 by adopting a genetic algorithm. The optimal transportation scheme is obtained, the transportation cost is controlled, and the transportation service level is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of multimodal transport planning, and specifically relates to a method for optimizing the route of China-Europe land-sea express line China-sea-rail combined transport. Background technique [0002] The volume of cargo transportation between my country and Europe is large, and motors, electrical appliances, boilers, machinery, furniture, toys, clothing, and metal products account for a large proportion. Compared with products with strong timeliness requirements such as food and flowers, such products are more important for transportation The timeliness requirements are low, and the volume is large and the value is high. [0003] From the perspective of the characteristics and transportation requirements of the main transportation products between my country and Europe, the China-Europe Land-Sea Express Line adopts the main transportation mode of sea transportation and railway transportation, and gets rid of t...
