The invention discloses a single-vehicle streamline logistics transportation dispatching method on the basis of an immune genetic algorithm. Multi-yard single-vehicle streamline production logistics transportation dispatching can be implemented by the aid of the single-vehicle streamline logistics transportation dispatching method. The single-vehicle streamline logistics transportation dispatching method includes building multi-yard single-vehicle streamline logistics transportation dispatching models; determining basic factors, including production logistics transportation dispatching time windows, delivery periodicity, goods relevance, yard diversity and the like, of logistics transportation dispatching according to characteristics of streamline production modes; building mathematical models containing objective functions and constraint conditions; designing the immune genetic algorithm for the mathematical models; solving the mathematical models by the aid of the designed immune genetic algorithm. The single-vehicle streamline logistics transportation dispatching method has the advantages that streamline production logistics transportation dispatching can be effectively implemented for a multi-vehicle single delivery center by the aid of the designed algorithm, the solution quality of the algorithm can be improved to a certain extent, and the convergence rate of the algorithm can be increased to a certain extent.

Description

Technical field [0001] The invention relates to a method for logistics transportation scheduling of multiple parking lots and single vehicle types in assembly line production. Background technique [0002] The logistics transportation scheduling problem of assembly line production is an important indicator to improve the efficiency of assembly line production. However, the current situation of China's logistics is not very optimistic. The "Analysis of Logistics Operation in 2013 and Outlook for 2014" shows that from the perspective of industrial structure, my country's first and second The industry accounts for a high proportion and the tertiary industry accounts for a low proportion. The ratio of the added value of the tertiary industry to GDP is not only far below the level of more than 70% in the United States and Japan, but also lower than the level of more than 60% in Brazil. This article points out the main problems facing logistics development: high logistics costs and low...

Problems solved by technology

This paper points out the main problems faced by logistics development: high logistics cost and low logistics profit; and a very important reason for the high cost is the waste of resources caused by unreasonable logistics transportation. The mission under the background of the assembly line production era

If the logistics, transportation and distribution are unreasonable, it will cause the operation in the supply chain to be busy and idle, and it will also cause material accumulation, which will affect the operation.

Reasonable logistics and transportation scheduling is the fundamental premise for orderly, reasonable and effective assembly line production. At present, there are very few studies on assembly line logistics and transportation scheduling at home and abroad. In the past, scholars often involved assembly line production scheduling.
