Introduction

The user can apply production constraints to the 4C Supply® model per dispensing unit. These constraints will be applied during forecast calculation (production planning and production plan validation).

Dispensing unit code

Defines to which dispensing unit a group of production setting apply. Dispensing unit codes in the production settings table have to match specified dispensing unit codes in the dispensing units table. If an invalid dispensing unit code is entered for a table row, a warning with the following message is shown:

Min Production Quantities

Defines the minimum number of kits in a production. Must be an integer. If an invalid entry is made, no error is raised, but the entry will not be interpreted.

Max Production Quantities

Defines the maximum number of kits in a production. Must be an integer. If an invalid entry is made, no error is raised, but the entry will not be interpreted.

Note, depending on the quantity, this could create stock out situations in combination with other production settings.

Production Interval [months]

Defines the interval between productions. This interval can either be defined as a single static value for the duration of the study using Production Interval as the column header or dynamically, using two columns with the headers Production Interval before LPI and Production Interval after LPI.

Productions will be scheduled in (multiples of) the specified production interval. Must be specified in months. Unit (months) must be specified in column header and values must correspond to months.

Must be an integer. If an invalid entry is made, no error is raised, but the entry will not be interpreted.

Dispensing units in the same blinding group must have the same production interval. If a different production interval is specified for a dispensing unit than other dispensing units in the same blinding group, a warning with the following message is shown:

Note: Defining a production interval does not force productions to occur in exactly that interval. Instead, it forbids productions to occur outside the interval. For example, setting a production interval of 6 months can lead to production in the following months depending on demand and cost optimization:

• 1, 7, 13, 19, 25

• 1,13, 25

• 1, 13, 19, 25

To force an exact production interval, use a Planned Lots table to define productions in the required cadence and specify that the scenario should use planned lots only (see below).

Planned lots only

Defines whether existing and planned lots only should be used in production planning. Accepts values true and false. Default value is false. If an invalid entry is made, no error is raised, but the entry will not be interpreted.

Defining planned lots only as ‘True’ for any Dispensing Unit in this table will restrict 4C Supply from creating any productions that are not specified in the Planned Lots table.
