Rozważ problem z planowaniem pracy pielęgniarki w konkretnym szpitalu. Codziennie w godzinach 7, 13 i 19 występują 3 korekty 12-godzinne. horyzont planowania to 4 dni, począwszy od 1 maja 2023 r., łącznie 12 zmian. Na te zmiany można przypisać 4 zarejestrowane pielęgniarki, potrzeby dwóch pielęgniarek jednocześnie. Zasięg jest wymagany.
Wszystkie pielęgniarki muszą odpocząć między zmianami przez co najmniej 12 godzin (720 minut) oraz może pracować maksymalnie przez 36 godzin (2160 minut) w określonym horyzoncie planowania. Te ograniczenia mają odpowiednio wysoki i średni priorytet.
Kilka zmian dziennie
Trzy zmiany dzienne są przedstawiane jako 3 niezależne zmiany. Przykład: korekty pierwszego dnia (z 4 dni) w „dziale”, Lokalizacja to reprezentowane jako:

Odpoczynek między zmianami
Aby odzwierciedlić resztę zmian między zmianami pracownika, użyj funkcji
minimumRestMinutes – pole z
ograniczenie harmonogramu. Czas rozpoczęcia i zakończenia
to ograniczenie służy do określania, które zmiany należy wziąć pod uwagę,
powinny być dopasowane do horyzontu planowania i zachodzić na wszystkie zmiany.
czas odpoczynku jest podawany w minutach (720), a priorytet wynosi PRIORITY_HIGH jako
wspomniane powyżej. Pierwsza pielęgniarka (Adam) jest przedstawiana jako:
{
"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
}]
}
}
Maksymalny czas pracy
Maksymalny czas, przez jaki pracownik może pracować również, jest również przedstawiany za pomocą
ograniczenia harmonogramu, używając maximumMinutes
. Maksymalny czas pracy w tym przykładzie to 2160 minut. Początek
czasy zakończenia ograniczenia powinny być dopasowane do całego horyzontu planowania.
Reprezentację pierwszej pielęgniarki (Adama) można zmienić na:

Ubezpieczenie dla uprawnionych pielęgniarek
Zasięg 2 zarejestrowanych pielęgniarek w danym momencie jest reprezentowany za pomocą
wymagań dotyczących pokrycia. W szczególności
Pole roleRequirements zostało wypełnione wartością 1
wymagana rola, dla której atrybut roleId ma wartość
„Zarejestrowana pielęgniarka” i ustawienie targetEmployeeCount ma wartość 2, a priority –
PRIORITY_MANDATORY Czas rozpoczęcia i zakończenia wymogu ochrony
i nakładają się przy każdej zmianie. Pole locationId jest ustawione na „dział” tak aby
uwzględniane są tylko zmiany zachodzące w tej lokalizacji.
