Abstract: To solve the balance of aircraft pulse assembly line,a balance model in the workstation for aircraft pulse assembly line was constructed.By considering the constraints of assembly line Takt and daily access time,a multi-objective optimization mode was proposed to obtain the best assembly sequence and most suitable count of working group,which could achieve the highest overall efficiency of working groups and working balance among working groups.Genetic algorithm based on sequenced coding scheme was applied to solve the problem.To improve algorithm efficiency,all evolutions including chromosome initialization,chromosome crossover and chromosome variations were considered based on sequenced coding scheme.The experiment results showed the efficiency and feasibility of the proposed method.
