| | Production ModelRepetitive manufacturing is used when the production process is
a continuous, and steady stream of demand. This demand must be met using
minimal administrative effort, but with real-time insight and control of the
process. In a repetitive manufacturing environment, products are manufactured
based on predefined configurations that are specified in production models. A production model contains all master data required for the
production of an item in a specific work cell. An end item can have multiple models defined for manufacture, to
differentiate between these models each has a unique key. A production model is revision controlled, and must be activated
by setting the status to Approved before production can start. You can make
changes to a production model by copying an existing model. The copied model
will have the status New,
becoming the new revision upon activation and approval. Old production models
are deactivated by setting the status to Expired. Note You can copy a production model to another item or another work cell. A production model contains this data: Production model code A production model can be used for planning and costing
purposes. When multiple models for the production of a repetitive item are
used, you must designate which models are used for this purpose. Note: Only
active production models can be used for planning and production. The
production model contains a calendar that is defaulted from the work cell that
is used by the scheduling engine to manage production. A production model can
be linked to a calendar. Applicable item and the dedicated work cell Along with the item data, the warehouse where completed
manufactured items are stored. Current revision A revision number is mandatory for a production model, and
is used to track the changes to the model. The revision number is generated
automatically. Production rate The time required for one cycle of production for one item,
or production rate is stored in the production model. Run quantity The order quantities used for material planning outside the
scheduling horizon and order lead times used for material planning outside the
scheduling horizon are maintained in the production model. The optimal, maximum
and minimum run quantities that are used for planning and during the creation
of the production run schedule are also maintained. Man capacity Expressed in the number of shifts and man-hours allocation
which are stored with the production model Material list You can define the material list for a production model in
the Materials (tirpt2120m000) session. The list contains the materials required for the production
of the specific item. It is used for materials planning, the supplying of the
work cell and material backflushing. The material list is date effective, and
when updated a new revision of the production model is defined. A production model list of materials defines the required quantities of each material, and the
expected scrap percentage, the units of measure, and supply warehouses
responsible for the materials. It is possible to define multiple supply lines
for the same material, so each line has a position number. Materials are supplied to the designated point of usage warehouse for the consolidated material demand for the active
schedule lines in a specific period accounting, for the safety stock in the point of usage. Each material line is linked to a point of usage that requires specific material for production. The materials are
supplied from a warehouse to the point-of-usage independent from the material
demand. The replenishment is based on a Kanban card.
Multi-product production model To use multi-product production models: - The Multi-Product Production check box in the Repetitive Manufacturing Parameters (tirpt0100m000) session must be
selected.
You can define a production model with multiple end products
that are produced in different quantities. A list of products is added to the
single-item model containing the information about the different items the
model is set up for, and their quantities. In this type of production model the main tool used for
production is the information carrier to identify the model for planning and
costing. In the Work List (tirpt4602m000) session, the number of realized cycles of the tool
is reported instead of the quantity of item completed as with a single-item
model. Note - The planning, scheduling and costing is done on the end
product, not the tool.
- Work station based reporting and transfer quantity data are
not available in the multi-product repetitive environment.
- You cannot reject produced items in the multi-product repetitive environment.
- Process inspections are not possible in a multi-product
repetitive environment.
