To group resources further, your organization may define a hierarchy of

workstation, a milling workstation, and an inspection workstation. The- J3 k" Z! d( p7 R0 I" Z3 ~
welding line may contain a welding workstation and a welding work cell., |7 J/ x& a# Y& | M
You configure each work area with standard equipment, and you can
