醫(yī)院門診藥房揀選系統(tǒng)建模與優(yōu)化設(shè)計

醫(yī)院門診藥房直接面對患者,是醫(yī)藥物流不可分割的一部分。傳統(tǒng)藥房設(shè)施陳舊、以人工作業(yè)為主的藥品揀選效率低下,由此導(dǎo)致患者取藥排隊等待現(xiàn)象十分嚴重。因此,對門診藥房揀選系統(tǒng)進行優(yōu)化設(shè)計以提高藥房工作效率有十分重要的現(xiàn)實意 義。本文在淺析淺析某醫(yī)院門診藥房處方特點、患者排隊特點基礎(chǔ)上,對藥房揀選系統(tǒng)進行建模仿真,重點研究了門診藥房揀選對策、揀選設(shè)備選擇、服務(wù)窗口設(shè)置不足,旨在提高門診藥房揀選系統(tǒng)運行效率,減少患者取藥等待時間。首先,運用物流系統(tǒng)的淺析淺析策略和理論,詳細淺析淺析了門診藥房揀選系統(tǒng)組成要素。實際調(diào)研某醫(yī)院一天處方資料,并對其進行EIQ淺析淺析和ABC淺析淺析,得出處方和藥品揀選特點。在此基礎(chǔ)上,兼顧藥品存儲、分揀的特殊性,確定藥品的分揀方式、分揀對策,并選擇兩種揀選設(shè)備分別對不同特點藥品作業(yè)。其次,針對該醫(yī)院處方資料及藥房取藥流程,運用Petri網(wǎng)建模,用以描述自動揀選、電子標簽揀選兩種不同揀選流程及合并訂單流程。為驗證該揀選系統(tǒng)的可行性,本文運用Flexsim軟件進行仿真并優(yōu)化。仿真結(jié)果表明,該設(shè)計基本能滿足該醫(yī)院高峰時期的藥品分揀需求。最后,本文運用排隊論建立患者排隊模型,并通過實地觀察該醫(yī)院患者取藥情況,確定患者到達分布參數(shù)。結(jié)合藥品揀選效率,在Matlab中對不同服務(wù)窗口數(shù)目下的患者取藥過程進行仿真。通過對比患者所排隊列的平均隊長、平均等待時間、平均停留時間等參數(shù),并考慮藥房的成本投入,合理確定取藥窗口數(shù)目。通過對門診藥房揀選系統(tǒng)設(shè)計及優(yōu)化,提高了藥品揀選效率,降低了藥品分揀出錯率,減輕了藥房工作人員勞動量,可以為藥房工作人員創(chuàng)造安全、舒適的工作環(huán)境。同時,合理安排取藥窗口,減少了患者取藥排隊等待時間,提高了患者滿意度。

【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 There are mostly outdated equipped and inefficient medicines picking system in traditional pharmacies, which make the patients wait for a long time to get the medicine.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.
