| Abstract | This paper is a case study on improving the operation of mobile rack performance in semiconductor back-end test process. The mobile racks facilitate space utilization when storing, but constrain aisles when picking. We have considered eight possible combinations of the as-is and thee basic improvement suggestions with three possible traffic volumes (high, medium, low), which multiply into the total of 24 scenarios. Arena was used to simulate the mobile rack’s storage and picking operations. In the end, we compare expected labor cost reduction with the implementation cost of suggestions for benefit to cost analysis. The analysis recommends implementing two suggestions; improving barcode system and installing more mobile rack bays. |
