Abstract

The invention discloses a global optimization method for multi-thread operation of AGVs used for scheduling of cigarette ingredients. The method comprises the following steps: constructing a time sequence constraint matrix and a resource constraint matrix; initializing particle swarm by adopting a random generation task priority and an execution method; encoding particle individuals according to arandom rule and a random execution method; decoding the particle individuals; calculating a local optimal solution of the particle individuals and a global optimal solution of initial particle swarm;and updating the particle individuals based on the local optimal solution and the global optimal solution, and randomly changing the value of a certain coding position to generate new particle individuals. According to the global optimization method for multi-thread operation of AGVs used for scheduling of cigarette ingredients, updating iteration is conducted on all the particles by means of local solutions and global optimal solutions of the individuals in all the stages, and mutation operators are added to increase population diversity, so the advantages that a particle swarm algorithm iseasy to achieve and fast in convergence are reserved, proneness to falling into the local optimal solutions is avoided, and a solution can be provided for task scheduling of multiple AGVs in distribution operation.

Description

technical field [0001] The invention relates to the technical field of digital management of storage scheduling of auxiliary materials produced in cigarette factories, in particular to an AGV multi-threaded operation global optimization method for scheduling of auxiliary materials for cigarettes. Background technique [0002] In recent years, automated warehousing and smart logistics have been rapidly promoted in many industries, including the cigarette manufacturing industry. Through the technical transformation of new factories or original warehouses, many operations of warehousing of cigarette accessories, shredded tobacco, and finished cigarettes are performed by Efficient automation equipment assists in the completion, among which the automatic guided vehicle (AGV, Automated Guided Vehicle) has been widely used because of its advantages of being suitable for various working environments, flexible operation, and easy expansion. [0003] Before the production of cigarette...
