Programación de restaurantes

Piensa en un restaurante que planifica horarios semanales para la cocina. El los turnos en los restaurantes son de lunes a viernes, de 12 a.m. a 23 p.m. Existen cinco empleados que pueden realizar tres funciones: Station chef, Head chef y Sous chef. En cada turno, tiene que haber dos empleados que trabajen como Station chef con prioridad alta y otro que trabaje como Sous chef con prioridad. Además, se requiere un Head chef los martes y viernes con prioridad media. La única otra restricción de programación es para uno de los empleados, Liam, que solicitaron trabajo el “miércoles-2023-05-03”, pero no para trabajar en el cambio Friday-2023-05-05.

Cobertura de funciones para cada turno

Se puede especificar la cobertura de un rol específico para un conjunto determinado de turnos con una requisito de cobertura. Por ejemplo, el primer cambio de este problema puede representarse de la siguiente manera:

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

Si suponemos que los cinco turnos son: Monday-2023-05-01, Tuesday-2023-05-02, Wednesday-2023-05-03, Thursday-2023-05-04 y Friday-2023-05-05, el se representa el requisito de cobertura para los roles de Station chef y Sous chef como:

{
  "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"
      }]
    }
  ]
}

Para considerar el requisito de una Head chef, se agrega una cobertura adicional del requerimiento de cambios en los cambios necesarios. La lista completa de de cobertura es:

{
  "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"
      }]
    }
  ]
}

Solicitudes de empleados

Las solicitudes de los empleados se representan con la solicitud de turnos. . En este ejemplo, Liam solicitó trabajar en el turno del miércoles, pero no trabajará en el turno del viernes. Está representado (junto con sus roles) como:

{
  "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"
      }
    ]
  }]
}
