摘要: 考虑随机服务时间与行为特征互不相同的异质患者,建立随机混合整数规划模型对门诊预约调度问题展开研究。首先在给定服务顺序的假设下求解了两个患者的预约调度问题;在此基础上,设计启发式算法对多个患者预约方案和服务顺序同时进行优化。数值结果表明:当患者服务时间为独立同分布的随机变量时,患者预约时间间隔呈现先增加后减少的圆顶形状;当患者服务时间服从不同分布时,通过与样本平均近似方法对比,验证了启发式算法的计算效率和有效性。

Abstract: Given variety and complexity of diseases, along with uncertainty of patient behaviors, this article focuses on heterogeneous outpatients characterized by different service time and behaviors, and develops model to design optimal appointment scheduling rules. A stochastic mixed integer programming has been proposed to solve the appointment scheduling problem under the assumptions of patient heterogeneity in stochastic service duration distribution and patient no-shows. A heuristic algorithm has been presented based on a two-patients appointment scheduling system to solve the optimal arrival time of each patient. The numerical results suggest that when the service time for each patient are i.i.d. variables, the service time allocation exhibits a dome shape, i.e., job allowances initially increase and then decrease. When the service time distributions are different from each other, the efficiency of algorithm can be verified by comparing with sample average approximation method.

Key words: outpatient appointment scheduling, heterogeneous patients, random service duration, heuristic algorithm
