Application of Improved Artificial Fish Swarm Algorithm to Permutation Flow Shop Scheduling Problem

Artificial fish swarm algorithm (AFSA) is a novel swarm intelligent optimization algorithm.A new intelligent optimization was involved for scheduling problems.By analyzing the disadvantages of AFSA, this paper presents an improved artificial fish swarm algorithm(IAFSA).IAFSA adopts the order method based on exchanging list during the action of preying, and adopts an adaptive moving of small scale during the action of random move.According to the mathematic model of permutation flow shop scheduling, this paper provides the IAFSA-based solving strategy for the scheduling problem and discusses in detail the solving steps.The experiment results show that IAFSA has a stronger ability of global search and a better search efficiency, and it is feasible and valid.
