基于层次分析法的血筛实验室关键设备报废优先级评定模型的建立

AHP based model for assessing the scrap priority of key equipment in blood screening laboratories

目的建立血液筛查实验室关键设备的报废优先级评定模型,量化评估关键设备的可使用状态,为设备的报废提供科学依据。方法通过文献回顾法和德尔菲专家咨询法,从设备的应用性、经济性和先进性3个方面建立血液筛查实验室关键设备的报废指标。通过层次分析法计算相关指标的权重,根据设立的指标建立设备报废优先级的量化评定模型。提取检验科2020年1-12月设备运行数据使用模型进行分析,结合经验判断检验模型的准确性。结果共建立13项二级报废评定指标,层次分析后应用性、经济性和先进性3个一级指标的权重分别为0.582,0.114和0.306。共计30台关键仪器设备中,4台设备的模型评分<0.5,人工核验这些设备运行状况后同意其报废。结论通过建立血液筛查实验室关键设备的报废优先级评定模型,可准确地评定关键仪器的报废优先级,便于提前进行报废鉴定和采购预算编排,既可避免资源浪费又可保障检测工作的安全高效有序进行。

Objective To establish scrap indicators for key equipment in blood screening laboratory of blood centers and quantitatively assess the running status of key equipment,so as to provide a scientific method for equipment scrap.Methods Through the literature review and Delphi method,the scrap indicators of key equipment in blood screening laboratories were established in terms of applicability,economy and advancement of the equipment.The weights of relevant indicators were calculated by analysis hierarchy process(AHP),and the quantitative assessment model of equipment scrap priority was established according to the indicators and its weight.The equipment running data from January 2020 to December 2020 of Laboratory Department were collected and analyzed using the model,and its accuracy was verified based on experience.Results Thirteen second-level scrap indicators were established,and the weights of the three first-level indexes of applicability,economy and advancement were 0.582,0.114 and 0.306,respectively.Among the total 30 key equipment,the model score of 4 equipment was less than 0.5,and the running status after manually checking met the scrap standard.Conclusion The model can accurately assess the scrap priority of key equipment and facilitate the procurement budget and scrapping identification in advance,which can avoid the waste of resources and ensure safe,efficient and orderly laboratory work.
