摘要
目的探究与消化内镜维修成本和停机时间相关的主要失效元件。方法采用层次分析法,对四川大学华西医院2010年1月-2019年4月消化内镜的维修数据进行处理和分析。结果涉及110条消化内镜,大修理322次,小修理364次,共更换1 651件失效元件,其中更换失效元件数量前3名为按钮(380件,23.02%)、插入管(223件,13.51%)和镜片(179件,10.84%)。造成大修理维修成本高和停机时间长的主要失效元件为光电耦合器(F=849.702,P<0.001;F=9.525,P=0.002)和导光束(F=8.190,P=0.005;F=6.384,P=0.012),影响小修理维修成本的失效元件为镜片(F=25.464,P<0.001)和角度钢丝(F=5.652,P=0.018),延长小修理维修时间的失效元件是镜片(F=10.384,P=0.001)和电气接口(F=4.816,P=0.029)。结论对维修数据定量分析有利于客观分析维修成本和停机时间的主要失效元件。
Objective To explore the main failure components related to maintenance cost and downtime of gastrointestinal endoscopy. Methods The analytic hierarchy process(AHP) was used to process and analyze the maintenance data of gastrointestinal endoscopy in West China Hospital of Sichuan University from January 2010 to April2019. Results The results involved 110 gastrointestinal endoscopy, 322 major repairs, 364 minor repairs, and a total of1 651 failed components, in which the top three components were buttons(380 pieces, 23.02%), the insertion tubes(223 pieces, 13.51%), and lenses(179 pieces, 10.84%). The main failure components causing high maintenance cost and long downtime of major repairs were charge coupled devices(F=849.702, P<0.001;F=9.525,P=0.002) and light guides(F=8.190, P=0.005;F=6.384,P=0.012). The failure components affecting the maintenance cost of minor repair were lenses(F=25.464, P<0.001) and angle steel wires(F=5.652, P=0.018). The failure components prolonging the maintenance time of minor repair were lenses(F=10.384, P=0.001) and electrical interfaces(F=4.816, P=0.029). Conclusion Quantitative analysis of maintenance data is helpful to objectively analyze the main failure components of maintenance cost and downtime.
