Özet

The purpose of this study is to propose an efficient way to balance the u-shaped assembly lines with alternative subassembly graphs while minimizing the number of stations and maximizing the line efficiency. U-shaped assembly line balancing models with alternative subassembly graphs (uALB/sb) under consideration contains two kinds of special issues, i.e. the selection of a suitable subassembly graph among alternatives and the balancing according to the operational precedence constrained among the tasks in the selected subassembly graph. To deal with the multiple objectives and the special issues, first we designed this uALB/sb as a network problem and then proposed a multi-stage decision based genetic algorithm (mdGA). Additionally, in order to improve the performance of mdGA, we use fuzzy logic controller for fine-tuning of genetic parameters. Finally, uALB/sb problem has been solved using the proposed solution approach to highlight the applicability and performance of the proposed solution approach.
