Improvement of Hospital Outpatient Treatment Process Based on Value Flow Map, Queuing Theory and Flexsim Simulation

Abstract

In view of inappropriate hospital treatment process, this paper proposes improvement by combining value flow map and queuing theory. With outpatient treatment process of M Hospital as the research object, the existing outpatient treatment process is optimized using value flow map, the queuing model is determined by theoretical analysis of the index parameters of the two queuing models, and the Flexsim simulation software is used for modeling and simulation verification to evaluate the process optimization program. By analysis and improvement of value flow map, the outpatient treatment process time is reduced from 5528.8s to 4096.2s, with the movement time also reduced from 599s to 567s. According to simulation analysis, under the same situation, the M/M/n queuing model reduces the queue waiting time by 41151s compared with the M/M/1 queuing model in a period of 12600s, and the M/M/n queuing model can result in more balanced service window efficiency, with utilization rate of each window above 70%. The simulation results indicate the effectiveness of combining the proposed value flow map and queuing theory in improving outpatient treatment process.
