医院门诊药房拣选系统建模与优化设计
医院门诊药房直接面对患者,是医药物流不可分割的一部分。传统药房设施陈旧、以人工作业为主的药品拣选效率低下,由此导致患者取药排队等待现象十分严重。因此,对门诊药房拣选系统进行优化设计以提高药房工作效率有十分重要的现实意 义。本文在浅析浅析某医院门诊药房处方特点、患者排队特点基础上,对药房拣选系统进行建模仿真,重点研究了门诊药房拣选对策、拣选设备选择、服务窗口设置不足,旨在提高门诊药房拣选系统运行效率,减少患者取药等待时间。首先,运用物流系统的浅析浅析策略和理论,详细浅析浅析了门诊药房拣选系统组成要素。实际调研某医院一天处方资料,并对其进行EIQ浅析浅析和ABC浅析浅析,得出处方和药品拣选特点。在此基础上,兼顾药品存储、分拣的特殊性,确定药品的分拣方式、分拣对策,并选择两种拣选设备分别对不同特点药品作业。其次,针对该医院处方资料及药房取药流程,运用Petri网建模,用以描述自动拣选、电子标签拣选两种不同拣选流程及合并订单流程。为验证该拣选系统的可行性,本文运用Flexsim软件进行仿真并优化。仿真结果表明,该设计基本能满足该医院高峰时期的药品分拣需求。最后,本文运用排队论建立患者排队模型,并通过实地观察该医院患者取药情况,确定患者到达分布参数。结合药品拣选效率,在Matlab中对不同服务窗口数目下的患者取药过程进行仿真。通过对比患者所排队列的平均队长、平均等待时间、平均停留时间等参数,并考虑药房的成本投入,合理确定取药窗口数目。通过对门诊药房拣选系统设计及优化,提高了药品拣选效率,降低了药品分拣出错率,减轻了药房工作人员劳动量,可以为药房工作人员创造安全、舒适的工作环境。同时,合理安排取药窗口,减少了患者取药排队等待时间,提高了患者满意度。
【Abstract】 Hospital outpatient pharmacies, which directly face to patients, are an integral part of medical logistics. There are mostly outdated equipped and inefficient medicines picking system in traditional pharmacies, which make the patients wait for a long time to get the medicine. So it is meaningful to improve the efficiency of the outpatient pharmacy by redesigning and optimizing the medicine picking system.In this paper, based on the analysis of the prescriptions of hospital outpatient pharmacy and the queue feature characteristics of the patient, the medicine picking system for pharmacy is modeled and simulated, which includes the picking strategy, the equipment selection and the service window planning. The purpose is to improve the efficiency of the picking system and save waiting time for the patients.First, using the theory and method of logistics system, the elements of picking system for outpatient pharmacy are analyzed in detail. We get the characteristics of the prescriptions and items by analyzing the data on a certain day of a hospital using methods of EIQ and ABC. In addition, combining with the particularity of the medicine storage and picking, we determine the picking strategy and two different equipments.Second, based on analyzing the pharmacy and the outpatient pharmacy working process, a model is built using Petri-net to describe two different picking processes and order consolidation process. In order to verify the feasibility, the picking system is simulated and optimized using Flexsim. The experimental results prove the validity of the picking system, which can meet the hospital demand during the peak medicine picking.Finally, in order to make sure the plan of the service window, a patient’s queue model is built using queuing theory, and the parameters of the patients coming distribution function are obtained from observation and statistics, which are simulated with different numbers of service windows. By comparing the average length of the queue, the average waiting time, the average stay time as well as taking the cost of pharmacy into account, the number of the service window is determined.By designing and optimizing the medicine picking system, we improve the medicine picking efficiency, reduce the error rate and decrease the amount of worker labor, in order to provide a comfortable environment for the pharmacists. At the same time, the number of the service window is reasonable, which can reduce the waiting time and improve patient satisfaction.
