门诊到住院过程中病床负荷公平性的病人路由策略

在调研分析住院病人历史数据和医院业务流程基础上,建立了病人流路由分配的单排队多服务台队列倒V模型.以病房工作负荷公平性为目标,分析了RMI(randomized most-idle)随机路由分配策略的马尔科夫过程在倒V模型中的应用,得到了系统的阻塞概率及病床占用率等相关性能指标参数,从理论上分析了RMI路由分配策略的公平性.对比了两服务台队列占用率、单位时间内服务的病人数量,结果验证了RMI策略的公平性.

Patient Routing Based on Beds Fairness from Outpatient Department to Internal Wards

Based on theoretical analysis of flowchart and mass patient flow data， an inverted-V model with single patient queue and several heterogeneous server pools was established to describe patient routing allocation process. With the goal of routing allocation fairness for the beds of internal wards， the application of Markov process of randomized most-idle (RMI) routing policy in the inverted-V model was analyzed. The occupied and service rates of sever pools under different routing policies were obtained， and the routing policy fairness was analyzed theoretically. The experimental results showed the occupied and service rates for different server pool under RMI policy are more balanced than that of the average allocation policy.
