  • Model Studio and Model Manager

    In SAS Viya
    Seven stockout models compared on the same held-back weeks. The champion is registered in Model Manager, and a challenger is retrained every week.
    In Lantern
    Each action shows the rule that raised it and, for stock risks, the champion’s probability.

  • Intelligent Decisioning

    In SAS Viya
    Two rule sets turn a model score into an action: six rules choose what to do, fourteen set priority, owner and review.
    In Lantern
    The reason and the owner on every card come straight from these rules.

  • Job Execution

    In SAS Viya
    A scheduled job rebuilds the actions every Monday at 06:00 and reads back what people decided.
