Restriction Categories
Definition
The system supports six restriction categories for mapping certain characteristics:
Quantity Restriction
You use quantity restriction to limit the occurrence of a characteristic to either a minimum or a maximum quantity.
Spacing Restriction
You use spacing restrictions to limit the occurrence of a characteristic to a minimum spacing in the planned sequence of orders.
Block Restriction
You use block restrictions to limit the occurrence of a characteristic to a certain number of consecutive products.
NoteIt does not make sense to use block restrictions with the prioritized equal distribution procedure as the aim of this procedure is to distribute the variants evenly over the planning period.
End of the note.K-in-M Restriction
You can use the ‘K in M’ restriction to restrict a characteristic to a minimum or maximum quantity within a certain interval, such as a maximum of three out of five vehicles have air conditioning.
Position restriction
You can use position restrictions to limit the occurrence of a certain characteristic to a certain position or to a partial sequence.
Equal Distribution
You can use equal distribution to evenly distribute the occurrence of a certain characteristic over the planning period.
Integration
The
LP Procedure
you use for multiline planning can only take the
quantity restrictions
into account. If you also want a spacing restriction, a K-in-M restriction or a position restriction to be taken into account by the LP procedure, you have to define that these restrictions are to be converted into a
quantity restriction
in planning. You do this for these restriction categories in the
Conversion
field in restriction maintenance. See also: Multiline Planning with the LP Procedure
