Keywords:
Assembly line balancing, Semi-trailer production, Genetic algorithm, Auto-tuning parametersAbstract
In semi-trailer production, the mixed assembly line balancing is one of important work to increase productivity. Flat bed & low bed semi-trailer and container chassis semi-trailer are two products in the same family which is assembled in the same line. Then, the assembly line is mixed models implemented for utilizing resources. At the number of workstations is fixed, the averaged cycle time is the objective function of the problem solving, so it could response the several demands today. However, this research problem is well-known as NP-hard, and it is very hard to solve by mathematical models. Thus, the meta-heuristic such as Genetic algorithm (GA) is introduced to balance the mixed-models line of the case study. Moreover, Adaptive genetic algorithms including GA with Rough auto-tuning parameters (GA-RA) and GA with Fine auto-tuning parameters (GA-FA) are developed to apply the same problem and compare with the simple GA. In summarized, the GAs could be used to balance the mixed-models line, and GA-FA is the best effectiveness.
