java - 采用 DRL 文件来启用强制类次计数和连续/实时规划

Question

我正在寻找有关以下 DRL 文件的改进方法的任何建议，以强制执行一定数量的轮类。我当前的方法通过 int TotalInt 值来划分员工的 ShiftAssignment 计数总数。需要一个基于规划元素进展的乘数。这似乎可以很好地确保满足员工每两周所需的轮类时间。例如，员工 1 - x 必须每两周轮类 10 次，员工 x - 20 必须每两周轮类 9 次，等等。这在持续计划推进期间是正确的。不幸的是，这是 DRL 文件中的硬编码方法。我不知道如何通过 Java 类和方法来解决这个问题。非常感谢任何建议。

Answer 1

你不能改变数学吗？看来您正在检查 totalInt 下降的时间间隔。您可以直接除以 $constractLine.getMaximumValue() 来获取系数，而不是检查 28 个场景。

例如

coefficient = Math.ceil(totalInt/$contractLine.getMaximumValue());
score = (coefficient *  $contractLine.getMaximumvalue() - totalInt ) * coefficient;
scoreHolder.addSoftConstraintMatch(kcontext, score);

我没有检查所有边缘情况，但这应该达到与您使用 28 个间隔所做的相同的效果(并且具有更广泛的范围)。
