Abstract: Under the consideration of product demand ratio,a new method to adjust the operating costs was proposed,and the multi-objective optimization model for mixed-model assembly line balancing problem was formulated.An improved genetic algorithm base on natural number code and topological sorting was designed to solve the model.The crossover and mutation operation of standard genetic algorithm was improved to protect excellent genes,and the population expansion mechanism was proposed.Through testing for benchmark problems,the results showed that the proposed algorithm could decrease the cycle time and optimize product processing costs,and the improved genetic algorithm also had a significant effect in decrease computing time.

Key words: mixed-model assembly line, multi-objective optimization, genetic algorithms
