The test verifies the demand policies.

The supply situation is such that half of the demand can be met in time, and half of it late:

  • Demand: 20 on due date 5 Jan
  • Supply: 10 available as inventory, and 10 arriving on 10 Jan

The demand policy controls how the demand is allowed to be planned in such a constrained situation:

  • Case A:
    The default policy is to allow demands to be planned without any limits on the timing and quantity of the deliveries.
    Result: Delivery of 10 units on 5 Jan and a second delivery on 10 Jan.
  • Case B:
    No lateness is allowed.
    Result: A delivery of 10 units on 5 Jan.
  • Case C:
    Lateness is allowed, but we only accept a delivery for the full requested quantity.
    Result: A delivery of 20 units on 10 Jan.
  • Case D:
    No lateness is allowed, and we also only accept a delivery for the full requested quantity.
    Result: No delivery planned.
  • Case E:
    The maximum allowed delivery date is jan 7, without any restriction on the delivered quantity.
    Result: A delivery of 10 units on 5 Jan
  • Case F:
    The minimum quantity shipped is 11, without any restriction on the delivery date.
    In this case the onhand on jan 5 is increased to 15.
    Result: A delivery of 20 units on 10 Jan
