| Abstract | This thesis implementedtwo assembly line balancing algorithms to solve assembly line balancing problem of the stitching assembly production lines in a shoe factory. The user interface is done via Excel spreadsheet and the algorithms are implemented in Visual Basic for Application. The first algorithm is to solve assembly line balancing problem with single product model where the objectiveto minimize the cycle time. Ant colony optimization is applied in this algorithm. The solution method is divided into two stages. The first stage isto identify feasible sequence of tasks to be used in the assignment of tasks to stations in the second stage. Practical constraints considered in the task assignment process include task splitting and extra time allowance for operation and reassignment of tasks to stations after adding time allowances. The second algorithm is to solve or re-balance an existing assembly line when a new or similar product model is added to an existing production line. The task assignment can be done more efficiently by keeping high degree of similarity for task assignments. As a result, the objective for the second algorithm is to achieve high degree of similarity for task assignment between multiple product models (previous and new product models). The algorithm starts by finding a feasible solution for the new product model and then applies a heuristic to calculate mean similarity factor which is used to find the good task assignment for multiple product models.For the single model algorithm, the experimental results demonstrated that the single model algorithm is efficient for solving the assembly line balancing problem in terms of better balance efficiency and upper limit of station load. For the multiple models algorithm, an improvement on upper limit of station load is obtained by the proposed algorithm. The experimental results are reported, and the future studies are also suggested. |
