Abstract:

Aiming at the flexible job shop scheduling problem with AGV (automated guided vehicle), a dual resource integrated scheduling optimization model with the objective of minimizing makespan is established. In the process of population initialization, a heuristic initialization method is proposed to improve the quality of population initial solution and accelerate the convergence speed of the algorithm. A hybrid discrete particle swarm optimization algorithm that can effectively avoid premature maturation is proposed by combining the competitive learning mechanism and the random restart mechanism to address the disadvantages of discrete particle swarm algorithms that are prone to premature maturation. Simulation experiments are carried out on the baseline data set of flexible job shop scheduling considering job transport. The results show that heuristic initialization method and hybrid discrete particle swarm optimization algorithm are feasible and efficient in solving such problems.

Key words: flexible job shop scheduling, automated guided vehicle, discrete particle swarm algorithm, integrated scheduling
