חשבו על בעיה של תזמון אחות במחלקה בבית חולים מסוים. בכל יום יש שלוש משמרות של 12 שעות החל מ-7 שע', 13 שע' ו-19 שע'. אופק התכנון הוא ארבעה ימים, החל מ-1 במאי 2023, ובסה"כ 12 משמרות. יש ארבעה אחיות רשומות שאפשר להקצות למשמרות האלה, לאפשר עבודה של שתי אחיות במחלקה בכל זמן נתון. הכיסוי זוהי דרישה.
כל האחיות צריכות לנוח בין משמרת למשך 12 שעות לפחות (720 דקות), יכול לעבוד לכל היותר 36 שעות (2,160 דקות) במהלך אופק התכנון שצוין. המגבלות האלה קיבלו עדיפות גבוהה ובינונית, בהתאמה.
כמה משמרות ביום
שלוש התאמות ביום מיוצגות כשלוש התאמות בלתי תלויות. לדוגמה, משתנה ביום הראשון (מתוך ארבעה ימים) ב"מחלקה" מיקומים הם מיוצגת בתור:

מנוחה בין משמרות
כדי לייצג את השאר בין המשמרות של העובד, משתמשים
שדה minimumRestMinutes מתוך
אילוץ של תזמון. זמני ההתחלה והסיום
אנחנו משתמשים באילוץ כדי לקבוע אילו שינויים צריך לקחת בחשבון,
צריכה להתאים לאופק התכנון על ידי חפיפה עם כל השינויים.
זמן המנוחה מצוין בדקות (720) והעדיפות היא PRIORITY_HIGH בפורמט
שצוינו למעלה. האחות הראשונה (שנקראת Adam) מיוצגת באמצעות:
{
"employees": [{
"id": "Adam",
"roleIds": ["Registered Nurse"],
"schedulingConstraints": [{
"priority": "PRIORITY_HIGH",
"startDateTime": {
"year": 2023,
"month": 5,
"day": 1,
"hours": 7
},
"endDateTime": {
"year": 2023,
"month": 5,
"day": 5,
"hours": 7
},
"minimumRestMinutes": 720
}]
}
}
זמן עבודה מקסימלי
משך הזמן המקסימלי שבו עובד יכול לעבוד מיוצג גם באמצעות
אילוץ תזמון, באמצעות maximumMinutes
השדה הזה. זמן העבודה המקסימלי בדוגמה הזו הוא 2,160 דקות. ההתחלה ו
זמני הסיום של האילוץ צריכים להתאים לכל אופק התכנון.
אפשר לעדכן את הייצוגים המקבילים של האחות הראשונה (אדם) כך:

כיסוי לאחיות מוסמכים
הכיסוי של שתי אחיות מוסמכות בכל רגע נתון מיוצג באמצעות
דרישת כיסוי. באופן ספציפי,
אי אפשר להזין ערך אחד ב-roleRequirements
דרישת תפקיד שלפיה roleId מוגדר
הערך בשדה 'אחות רשומה', targetEmployeeCount מוגדר לערך 2, והערך priority מוגדר לערך
PRIORITY_MANDATORY. שעות ההתחלה והסיום של הכיסוי הנדרש
תהיה חפיפה עם כל שינוי. השדה locationId מוגדר כ'מחלקה' כך
רק שינויים שמתרחשים במיקום הזה מובאים בחשבון.
