The manufacturing planning model includes several interrelated process and
operation types, as follows:

Manufacturing process
A set of manufacturing process operations and other manufacturing
processes that are closely related to each other. It is a mechanism to group
operations into logical groups. It also maintains constraints on the order
of execution between subprocesses and process operations.

in the process structure. Optionally, you can break a process operation
into steps called activities. Examples of process operations include an

A unique location within the factory to which you can assign

A manufacturing facility in which operations and processes are executed.
% ~4 y+ K3 x. K" u- wThe plant structure is hierarchical structure of work areas of the factory
in which the product is manufactured. Its definition is independent of, but
related to, the manufacturing processes that are performed in it.

2 F" A& b! @9 {' Q# N3 s1 d! d! B" FAny element in the plant structure such as a factory, line, section, work
9 g* ]5 S8 R& _7 o5 O2 t( \cell, or station. Typically, a work area is assigned to one process operation.
A work area is defined by a location on the shop floor and the process
capability it provides.
To group resources further, your organization may define a hierarchy of
! Q+ V( _6 S9 {' o. o+ }work areas. For example, a plant may include a welding line, a lathe
: X4 p. S% }1 c+ t4 M( Q# P1 I" xworkstation, a milling workstation, and an inspection workstation. The
welding line may contain a welding workstation and a welding work cell.
You configure each work area with standard equipment, and you can
$ S, ^+ U2 K8 A4 s) ^further configure equipment that is needed to execute a specific process
operation. The process designer tries to use as much standard equipment
* d6 |: Z8 @+ u6 ?0 ]9 yin the work area as possible. If additional equipment is needed, the
/ d1 `$ t+ E1 K' [) Iprocess designer provides work instructions on how to configure the work
area with the additional equipment. For example, an NC machining
7 o! |9 ^! i/ M) Hcenter may be pre-loaded with standard tools that are commonly used on
8 T+ C9 Q) \7 {% r" gthe machine. If a process operation requires tools that are not pre-loaded,
the operator loads them on the machine when the particular process

The product structure defines the as-designed product. It is created by
the design engineers in a CAD system such as NX® and managed by
