Abstract
En 中文
U-shaped assembly line which has a better balance and a more compact space compared with traditional linear line derived from lean production. Aiming at balancing type-2 and -3 problem, learning effect and various constraints which cannot be ignored being added, an idea of combining learning effect with multiple constraints in actual production is put forward in this paper. Besides, the mixed nonlinear integer programming model is established for u-shaped assembly line to conduct a synthesis optimization for multiple optimized objects, and the improved genetic algorithm is being used for optimized solution. Finally, this model is applied to X company, and the weighted average load balance of each station and the assembly line rhythm as well as time fluctuation of the workstation are improved which verify the optimization of this model and the fitness of the improved genetic algorithm.
