Application research of hospital track logistics system
Objective Based on running record of hospital track logistics system of a large comprehensive tertiary hospi-tal in Guangdong-Hong Kong-Macao Greater Bay Area,perform statistical analysis and discussion,evaluate the application effect and provide a reference for further optimization of the system operation.Methods Use a directed graph to describe the network topology of the system,establish a multi-commodity flow model,and then select a week during the run-in operation period,nor-mal operation period,and holiday operation period,export the operation log,perform descriptive statistics,X2 test and interval estimation.Results The number of transportation vehicles during the normal operation period increased by 23.94％compared with the running-in operation period.The average transportation time during the running-in operation period,normal operation pe-riod,and holiday operation period were 1 015.63 seconds,1 176.83 seconds,and 1 106.38 seconds respectively;The lowest ranking is afternoon,morning,evening,and early morning;divided by date,the number of transported vehicles on weekdays is higher than that on rest days;the nodes with the largest proportion of sent transported vehicles are the central pharmacy and the inpatient building,and the nodes with the largest proportion of received transported vehicles are the inpatient building and the la-boratory department;the main track carrying relatively heavy transportation tasks is closely related to the important nodes.Conclusion The operation data of the hospital track logistics system should be fully utilized,comprehensive and in-depth analy-sis should be carried out in time,and the application effect should be evaluated,so as to provide a basis for further strengthening the rational allocation and use of related resources.
