基于收益管理方法的医院门诊预约挂号优化模型

Optimization of Outpatient Appointments Model Based on Revenue Management Method

基于收益管理方法,结合医疗行业特殊性,综合考虑医院收益与病人成本,运用马尔科夫决策过程理论和动态规划方法,建立了包含普通医生与专家两种医生类型的门诊预约挂号的存量控制优化模型,证明了模型在罚值不增时的先来先接受,目标值先增大后减小,阶段预留的号源与罚值成正比的性质,并针对模型的多维状态空间的不可计算性,给出启发式算法,得到相应的预约策略,实现了号源在预约和现场窗口挂号的合理分配。研究结果为指导医院及类似行业建立预约系统提供理论支持。

Based on revenue management method,this paper first deals with the transformation of patient＇s cost into penalty value and hospital＇s revenue by combining target function with Markova decision process theory and dynamic programming method,according to the current situation in Chinese hospitals including both ordinary doctors and specialists.Then an optimization model is established for the outpatient appointments and walk-in patients.It is proved that the model has three properties：（1） ＂first come first served＂ when the penalty does not increase,（2） the target value increases first and then decreases,and（3） the stage reserved source numbers are proportional to penalty value.In view of the incomputability of the multi-dimensional computational state space,we propose the corresponding heuristic algorithm,get relevant booking strategy,allot source number to outpatient appointments and walk-in patients.The theoretical support is provided to guide hospitals and similar industries to establish an appointment system.
