摘　　要：医院放射科门诊的患者调度是典型的作业车间调度问题。应用模糊移动瓶颈法求解放射科门诊患者调度问题,用三角模糊数表示不确定的服务时间、服务开始时间和结束时间。采用模糊排序方法,对每项医疗服务逐次做模糊单机调度,选择有最大延迟时间的服务为瓶颈进行调度,然后对已调度的服务重新进行优化。实例中对一家综合医院放射科门诊的患者服务流程,求出目标使模糊最大完成时间最小化的患者调度方案,计算结果可以为医院的管理决策提供参考。Patient scheduling in radiotherapy is defined as a job shop problem.In this paper,a fuzzy shifting bottleneck procedure is applied to solve patient scheduling problem.Triangular fuzzy numbers are used to model uncertain processing time,release dates and due dates of services.Fuzzy ranking operators are adopted in the fuzzy one-machine scheduling procedure,and the service with the maximum lateness is identified as the bottleneck to be scheduled and then re-optimized.In the case study of patient scheduling in radiotherapy at a polyclinic hospital,the objective of minimizing fuzzy makespan is solved while the patient scheduling solution is obtained.The results can provide some references for hospital managerial decision-making.
