摘要目的：建立科学合理的护士排班模型，以节约护理人力资源和护士长排班时间。方法将护士和患者分别分组，护士上班周期根据公约和公倍数原理，运用数学逻辑算法计算上班时间和休息替补排班，形成排班体系。结果建立了ST排班基本模型，以及在基本模型基础上增加了扩展模型一、二，以及合并模型一、二。结论根据患者数量、病情等情况，并在基础模型基础上与扩展模型自由组合，选择适合的排班模型，方便了护士长排班，缩短了排班时间，同时也规范了替补排班，使补充人员相对固定，节省了护理人力。

abstractsObjective To establish a scientific and rational nurse scheduling model for saving nursing human resources and schedule time for head nurses. Methods The nurses and the patients were divided into groups respectively. According to the principle of convention and common multiple, the mathematical logic algorithm was used to calculate working hours, rest and backup scheduling. Results ST basic scheduling model was established and the extension model 1, 2, and merge models 1, 2 was added on the basic of ST scheduling. Conclusions Based on the basic model, free combination and extension model, appropriate scheduling model was selected according to the number of patients and disease condition. It′s convenient which saves the scheduling time of the head nurses. At the same time, it standardizes the backup scheduling, fixes the backup nurses, and saves the nursing resources.
