A method for distributing tools to each machine in a 2-machine flowshop-type FMS with duplicated tools is proposed when there are precedence constraints on job operations. The duplicated tools are selected according to the from-to chart which represents the technical precedence constraints on the tools. Some simulation results show that the proposed method is effective for increasing the utilization of the FMS, especially when the utilization of the completely separated functional FMS is low.
