To group resources further, your organization may define a hierarchy of' U9 o2 t1 Y! @) N) N- q
work areas. For example, a plant may include a welding line, a lathe: F( k* u; T9 d
workstation, a milling workstation, and an inspection workstation. The

You configure each work area with standard equipment, and you can

in the work area as possible. If additional equipment is needed, the

area with the additional equipment. For example, an NC machining% P+ C: o/ s9 |3 o
center may be pre-loaded with standard tools that are commonly used on
