Lean Manufacturing to Reduce Time

There are 3 saws, 3 lathe, 2 grinder, 1 heat treatment, and 3 three press in a floor. The setup is shown below. The time taken for operation are saw-30s, lathe(1)- 65s, lathe(2)-15s, grinder – 15s, heat treatment – 20s, press – 10s. there are totally 11 workers. Set up the process that takes a least amount of time. SAW – LATHE – GRINDER – HEAT TREATMENT – LATHE - PRESS
