硬限制：

  • 无未分配的 转换（内置）：每个转变都需要分配给员工。
  • 改变冲突 ：员工每天只能有一个变化。

软限制：

  • 合同义务.业务经常违反了这些，因此他们决定将其定义为软限制，而不是硬约束。

    • 最小和最大分配 ：每个员工需要工作超过 x 的转换，少于 y 个转换（取决于其合同）。
    • 最小和最大连续工作天数 ：每个员工需要在一行内 x 到 y 天之间工作（取决于合同）。
    • 最少和最多连续的免费天数 ：每个员工都需要在行中的 x 到 y 天之间自由（取决于合同）。
    • 最少和最多的连续工作周末 ：每个员工需要在一行内 x 和 y 周末（取决于其合同）之间工作。
    • 完整周末 ：每个员工需要每天在周末或根本不工作。
    • 每周端的相同变化类型 ：同一员工的每周末的每周切换都必须相同转换类型。
    • 不需要 的模式 ：一行中不需要的转换类型的组合，例如，上次转换后接初的转换后再进行移动。

  • 员工希望：

    • 申请日 ：员工希望每天工作。
    • 第一天请求 ：员工不希望在特定日期工作。
    • 改变请求 ：员工希望被分配到特定的转变。
    • 转移请求 ：员工不希望分配到特定转换。
  • 备选技能 ：分配给技能的员工应具备该转变所需的每个技能的精通。

这个问题由 国际 Nurse Rostering Competition 2010 定义了。
