Manufacturing Rules
Manufacturing Rules
There are two types of rules available for generating manufacturing orders: Component Requirement and Labor Requirement.
· Component Requirement rules create component requirements and attach them to a manufacturing order. The user can also decide to use the standard bill of material of the configured product. In our example, we require the London model to have a bookshelf and the Stockholm model to have a disk file. We do not create any other component requirement rules such as ones for the desk size, color, or microcomputer table.
· Labor Requirement rules generate labor requirements consistent with the routing associated with the product and the sales options selected. In the example, we create a rule to say that the assembly time of the luxury model is seven hours more than the standard model. The user may also decide to use the standard routing for the product instead. Again, we do not create any labor requirement rules based on such options as the desk size, color, or microcomputer table.
Using the Manufacturing Rules File Maintenance conversation, we defined a component requirement for each model (bookshelf for London and disk file for Stockholm) and a component requirement for the luxury option. The Component Requirement rules for each option are as follows (see the Manufacturing Rule Maintenance Component Requirement Detail Screen for an example of the bookshelf):
|
Condition:
(O-LONDON,EQ,"Y")
Part Number:
"BOOKSHELF"
Quantity Per
1
|
|
If the London model is chosen
Then one bookshelf is required.
The number of components needed.
|
|
Condition:
(O-STOCKHOLM,EQ,"Y")
Part Number:
"DISKFILE"
Quantity Per
1
|
|
If the Stockholm model is chosen
Then one diskfile is required.
The number of components needed.
|
|
Condition:
(O-LUXURY,EQ,"Y")
Part Number:
"ROLLTOP"
Quantity Per
1
|
|
If the luxury option is chosen
Then one roll top is required.
The number of components needed.

The Manufacturing Rule Maintenance Component Requirements Detail Screen.
In the previous figure, the part number for the required component is preceded by two other fields, the usage code and the scrap factor. A component in a bill of material may either be used or produced (like a by-product) during the manufacturing process of the parent item. The usage code defaults to C, indicating that the component is used during the process. The scrap factor represents the amount of the component which will become scrap during the manufacturing process of the parent item. The scrap factor is figured into the component requirement.
Labor requirements were also defined in the Manufacturing Rules File Maintenance conversation for our desk example. We set up two operations, and assigned a piece rate for each option with labor requirement rules. We also defined a standard piece rate which all desks possess. The labor requirement rules for each option are as follows (see The London Model Desk below for an example of the London model):
|
Condition:
Oper No/Ln No/Comment No
"0100000"
Piece Rate
20
|

No condition, this is the standard labor requirement for all desks. Operation (0100000) will perform the assembly of this component.
