The invention discloses a multi-agent job shop negotiation scheduling optimization method. The method is divided into two stages: in the first stage, a scheme set is guided to evolve to a Pareto frontier in an inter-agent iterative negotiation mode; and in the second stage, the coordinator selects the scheme with the best social benefit from the scheme set based on the agent score. According to the method, each agent selects a part of random search schemes to put forward and form an initial parent scheme set; the coordinator performs crossover variation on the parent scheme set to generate a child scheme set, then ranks the parent and child scheme sets based on agents, and selects non-dominated schemes from the parent and child scheme sets to enter a new parent scheme set; and the negotiation is iterated for multiple times, and after a negotiation round is reached, the coordinator selects the scheme with the best social benefit from the scheme set based on the agent score. The method is based on the genetic evolution thought, and the optimization effect is effectively improved; and a more accurate information batch exposure mode is adopted, so that the social benefit is effectivelyimproved.
