Prenons l’exemple d’une infirmière qui a un problème de planification dans un service d’un hôpital particulier. Chaque jour, il y a trois quarts de 12 heures à partir de 7 heures, 13 heures et 19 heures. La de planification est de quatre jours, à partir du 01/05/2023, pour un total de 12 ajustements. Quatre infirmiers diplômés peuvent être affectés à ces quarts, avec la l'objectif d'avoir deux infirmières au service à tout moment. La couverture est obligatoire.
Toutes les infirmières doivent se reposer entre les quarts de travail pendant au moins 12 heures (720 minutes) et peut travailler au maximum 36 heures (2 160 minutes) au cours de la période de planification spécifiée. Ces contraintes ont respectivement une priorité élevée et une priorité moyenne.
Plusieurs quarts par jour
Trois quarts par jour sont représentés par trois quarts indépendants. Par exemple : d'ajustements pour le premier jour (sur quatre jours) dans le "service" sont représenté par:
{
"shifts": [{
"id": "2023-05-01 7hr",
"locationId": "department",
"startDateTime": {
"year": 2023,
"month": 5,

Repos entre deux quarts de travail
Pour représenter le reste entre les périodes de travail d'un employé, utilisez le
Champ minimumRestMinutes d'un
contrainte de planification. Les heures de début et de fin de
la contrainte sont utilisés pour déterminer
les changements à prendre en compte, et donc
doivent s'aligner sur un horizon de planification
en chevauchant tous les changements. La
le temps de repos est exprimé en minutes (720) et la priorité est définie sur PRIORITY_HIGH
comme indiqué ci-dessus. La première infirmière (appelée Adam) est représentée comme suit:
{
"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
}]
}
}
Temps de travail maximal
La durée maximale de travail d'un employé est également représentée par une
contrainte de planification, à l'aide de la maximumMinutes
. Dans cet exemple, la durée de travail maximale est de 2 160 minutes. Le début et
les heures de fin de la contrainte doivent s’aligner sur l’ensemble de l’horizon de planification. La
la représentation correspondante de la première infirmière (Adam) peut être modifiée comme suit:
{
"employees": [{
"id": "Adam",
"roleIds": ["Registered Nurse"],
"schedulingConstraints": [{
"priority": "PRIORITY_HIGH",
"startDateTime": {
"year": 2023,

Couverture pour les infirmiers diplômés
La couverture de deux infirmiers diplômés à un moment donné est représentée par une
exigence de couverture. En particulier,
roleRequirements est renseigné avec un
exigence de rôle pour laquelle roleId est défini sur
"Infirmier diplômé", targetEmployeeCount est défini sur 2 et priority est défini sur
PRIORITY_MANDATORY Les heures de début et de fin de l'exigence de couverture doivent
se chevauchent à
chaque équipe. Le champ locationId est défini sur "department". afin que
seuls les changements qui se produisent
à cet endroit sont pris en compte.
