Problem report

This screen shows a list of issues requiring the planner’s attention.

Each entity type has it’s own set of exceptions:

  • Demand:
    • unplanned: No plan exists yet to satisfy this demand.
    • excess: A demand is planned for more than the requested quantity.
    • short: A demand is planned for less than the requested quantity.
    • late: A demand is satisfied later than the accepted tolerance after its due date.
    • early: A demand is planned earlier than the accepted tolerance before its due date.
    • invalid data: Some data problem prevents this object from being planned.
  • Resource:
    • overload: A resource is being overloaded during a certain period of time.
    • underload: A resource is loaded below its minimum during a certain period of time.
  • Buffer:
    • material excess: A buffer is carrying too much material during a certain period of time.
    • material shortage: A buffer is having a material shortage during a certain period of time.
    • invalid data: Flagged when a buffer has no ways of replenishment or too many.
  • Operation:
    • before current: Flagged when an operationplan is being planned in the past, i.e. it starts before the current date of the plan.
    • before fence: Flagged when an operationplan is being planned before its fence date, i.e. it starts 1) after the current date of the plan but 2) before the current date of the plan plus the release fence of the operation.
