餐厅预约

假设有一家餐厅为厨房规划每周时间表。餐厅星期一至星期五 12 小时制至 23 小时制。公司共有 5 名员工,可担任三个角色:Station chefHead chefSous chef。在每个轮班中,需要有两名员工担任优先级较高的 Station chef,以及一名员工担任优先级为中等的 Sous chef。此外,优先级为中等的星期二和星期五也需要使用 Head chef。唯一其他的时间安排限制是针对其中一位请求在“2023-05-03”星期三工作的员工 Liam,但不负责执行 Friday-2023-05-05 轮班。

适用于每次班次的角色涵盖范围

您可以针对一组给定的班次指定特定角色的覆盖率,并满足覆盖率要求。例如,此问题的第一位移可以表示为:

  {
    "shifts": [
      {
        "id": "Monday-2023-05-01",
        "startDateTime": {
          "year": 2023,
          "month": 5,
          "day": 1,
          "hours": 12
        },
        "endDateTime": {
          "year": 2023,
          "month": 5,
          "day": 1,
          "hours": 23
        }
      }
    ]
  }

假设所有五个班次均为:Monday-2023-05-01Tuesday-2023-05-02Wednesday-2023-05-03Thursday-2023-05-04Friday-2023-05-05,则 Station chefSous chef 角色的覆盖率要求表示为:

{
  "coverageRequirements": [{
      "shiftIds": ["Monday-2023-05-01", "Tuesday-2023-05-02",
                  "Wednesday-2023-05-03", "Thursday-2023-05-04",
                  "Friday-2023-05-05"]
      "roleRequirements": [{
        "roleId": "Station chef",
        "targetEmployeeCount": 2,
        "priority": "PRIORITY_HIGH"
      }, {
        "roleId": "Sous chef",
        "targetEmployeeCount": 1,
        "priority": "PRIORITY_MEDIUM"
      }]
    }
  ]
}

如需考虑对 Head chef 的要求,可以针对必要的偏移指定额外的覆盖范围要求。完整的保修范围要求列表如下:

{
  "coverageRequirements": [{
      "shiftIds": ["Monday-2023-05-01", "Tuesday-2023-05-02",
                  "Wednesday-2023-05-03", "Thursday-2023-05-04",
                  "Friday-2023-05-05"],
      "roleRequirements": [{
        "roleId": "Station chef",
        "targetEmployeeCount": 2,
        "priority": "PRIORITY_HIGH"
      }, {
        "roleId": "Sous chef",
        "targetEmployeeCount": 1,
        "priority": "PRIORITY_MEDIUM"
      }]
    },
    {
      "shiftIds": ["Tuesday-2023-05-02", "Friday-2023-05-05"],
      "roleRequirements": [{
        "roleId": "Head chef",
        "targetEmployeeCount": 1,
        "priority": "PRIORITY_MEDIUM"
      }]
    }
  ]
}

员工请求

员工请求通过排班请求字段表示。在此示例中,Liam 请求在星期三的轮班上工作,但在星期五的班次上工作。这一点(以及他的角色)表示为:

{
  "employees": [{
    "id": "Liam",
    "roleIds": ["Station chef", "Head chef"],
    "shiftRequests": [
      {
        "priority": "PRIORITY_HIGH",
        "shiftIds": ["Wednesday-2023-05-03"],
        "type": "STATUS_WORK"
      },
      {
        "priority": "PRIORITY_HIGH",
        "shiftIds": ["Friday-2023-05-05"],
        "type": "STATUS_NOT_WORK"
      }
    ]
  }]
}

包含全部 5 名员工的示例

          }
        ]
      }
