レストランで週ごとのキッチンのスケジュールを計画しているとします。レストランの営業時間は月曜日から金曜日の 12 時間から 23 時間までです。Station chef、Head chef、Sous
chef の 3 つのロールを実行できる従業員が 5 人います。シフトごとに、優先度が高い Station
chef として 2 人の従業員が、優先度が中程度の Sous chef として 1 人の従業員が働いている必要があります。また、火曜日と金曜日には中程度の優先度の Head chef が必要です。他のスケジュールの制約は、従業員の 1 人（Liam）に対して「Wednesday-2023-05-03」の作業を依頼したものの、Friday-2023-05-05 シフトでは作業しないという制約です。
すべてのシフトをカバーするロール
特定のロールのカバレッジは、カバレッジ要件を使用して、特定のシフトセットに対して指定できます。たとえば、この問題の最初の変化は次のように表せます。
{
"shifts": [
{
"id": "Monday-2023-05-01",
"startDateTime": {
"year": 2023,
"month": 5,
"day": 1,
"hours": 12
},
"endDateTime": {
"year": 2023,
"month": 5,
"day": 1,
"hours": 23
}
}
]
}
5 つのシフトがすべて Monday-2023-05-01、Tuesday-2023-05-02、Wednesday-2023-05-03、Thursday-2023-05-04、Friday-2023-05-05 であるとすると、Station chef ロールと Sous chef ロールのカバレッジ要件は次のようになります。
{
"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"
}]
}
]
}
Head chef の要件を考慮する場合は、必要なシフトに追加のカバレッジ要件を指定できます。カバレッジ要件は次のとおりです。
{
"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"
}]
}
]
}
従業員のリクエスト
従業員のリクエストは、シフト リクエスト フィールドで表されます。この例では、Liam は水曜日のシフトには勤務するようにリクエストしていますが、金曜日のシフトには勤務しないようにリクエストしています。これは（ロールとともに）次のように表現されます。
{
"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"
}
]
}]
}
