Abstract:For the patients long time queuing problem, a public hospital carried out the field investigation and analysis, collecting data of the actual system, using SPSS software data analysis, conceptual models are established through the queuing theory of knowledge, then establishes the simulation model by Flexsim, substitution into physical parameters and run the simulation model, and confirmed by the simulation results, analyze the simulation results, optimized to improve, to achieve the optimization of treatment processes and service number, however, improve patients satisfaction and reduce the cost of hospital.
