摘要
为提高手术仪器设备维修资源调度效果,在医院信息化建设背景下,提出了手术仪器设备维修资源调度方法。采用Petri网构建设备维修资源模型,处理设备维修资源并定义资源选择域,以此为依据构建目标函数并采用遗传算法进行调度。通过遗传算法中的复制算子、交叉算子、保优操作、终止条件设置四部分操作,实现手术仪器设备维修资源调度。实验中将负载均衡、调度时间、召回率、资源调度能量消耗、调度准确性作为实验对比指标,结果表明,所提方法所提方法的负载情况与正常状态阈值相一致,召回率在92%~95%之间,资源调度能耗最高为13×103NJ,资源调度准确性为80%,因此,所提方法具备一定的实际应用意义。
In order to improve the scheduling effect of surgical instrument and equipment maintenance resources,a scheduling method of surgical instrument and equipment maintenance resources is proposed under the background of hospital information construction.The Petri net is used to build the equipment maintenance resource model,process the equipment maintenance resources and define the resource selection domain.Based on this,the objective function is constructed and the genetic algorithm is used for scheduling.The maintenance resource scheduling of surgical instruments and equipment is realized through four operations in genetic algorithm:replication operator,crossover operator,optimization operation and termination condition setting.In the experiment,load balancing,scheduling time,recall rate,resource scheduling energy consumption and scheduling accuracy are taken as experimental comparison indexes.The results show that the load of the proposed method is consistent with the normal state threshold,the recall rate is 92%~95%,and the maximum energy consumption of resource scheduling is 13×103NJ,the accuracy of resource scheduling is 80%,so the proposed method has certain practical significance.
