红帽全球峰会3.17. Nurse rostering (2010 年)
对于每个变动，为进行这种转变分配一元化。
硬限制：
- 没有未分配的 转换（内置）：需要将每个变换分配到员工。
- 改变冲突 ：员工每天只能有一个变化。
软限制：
合同义务。企业经常违反这些，因此他们决定将这些定义为软限制，而不是硬限制。
- 最小和最大分配量 ：每个员工都需要与 x 相比变化的工作多，且少于 y 个变化（取决于其合同）。
- 最小和最大连续工作日 ：每个员工都需要在 x 和 y 天之间工作（取决于其合同）。
- 最少和连续的免费天数 ：每个员工都需要在 x 到 y 天之间自由使用（取决于其合同）。
- 最小和最大连续工作周末 ：每个员工都需要在 x 到 y weekends 之间在一行（取决于其合同）之间工作。
- 完整周末 ：每个员工都需要每天每天工作，或者根本不需要工作。
- 每周端的相同转变类型 ：同一名员工的相同周末转换都必须是相同的转换类型。
- 不需要 的模式 ：一行中不需要的切换的组合，例如转换后再进行早期转换，然后转换。
员工希望：
- 申请 日期：员工希望在一个特定日期工作。
- 每天到期请求 ：员工不希望在某个特定日期工作。
- 行动请求 ：员工希望分配给一个特定变化。
- 转放请求 ：员工不希望被分配给特定变化。
- 备选技能 ：分配给技能的员工应精通该变化所需的各种技能。
问题由 2010 年国际子公司定义。
