Task duration as a PlanningVariable

[slxnxl]

In a task similar to the Food Packaging example, is it possible to calculate the duration of product packaging as a PlanningVariable? Product packaging capacity per hour is known. Can timefold itself set the duration of packaging of a particular product on the line depending on the needs (for example for 1 hour or for 3 days and 5 hours)? Thank you!

Yes, through a shadow variable you can add properties that change as the assigned line changes:

Although you probably don't even need a shadow variable. Something like this might suffice:

Duration getDuration() {
    return product.getDurationOnLine(line);
}
