High-mix low-volume production is required highly efficient manufacturing because frequent changes in manufacturing conditions increase setup time and equipment idle time. In the surface mounting process of high-mix low-volume production, multiple surface mounters are connected in order to improve efficiency. The allocation of parts to these surface mounters was determined based on the know-how of the operator, but the large number of parts made it difficult to plan the optimal layout, leading to the problem of longer manufacturing lead time. In this research, we developed an optimization technology for component placement using mixed integer programming and local search in order to plan the placement of electronic components to reduce manufacturing lead time in high-mix low-volume production with a large number of components. In this presentation, I will talk about the optimization technology of the component placement of the surface mounter and the evaluation results of the test line.
