Abstract：Objective Through the consistency test and improvement of the fuzzy complementary judgment matrix of the five
dimensions of the equipment, and then using the improved technique for order preference by similarity to ideal solution (TOPSIS)
to get the weight of each index affecting the comprehensive benefit of the equipment, the application effect of the comprehensive
benefit of the equipment in use is evaluated and analyzed. Methods By using the fuzzy comprehensive evaluation-improved TOPSIS
analysis, the weight of the index affecting the comprehensive benefit of equipment was scientifically and rationally distributed.
Results The weight of 13 indexes in 5 dimensions affecting the technical state of equipment,, economic benefit, social benefit,
reasonable allocation and scientific research benefit was W1= (C1=0.077, C2=0.077, C3=0.046, C4=0.031)T; W2= (C5=0.103,
C6=0.103,C7=0.075)T; W3= (C8= 0.052, C9= 0.078)T; W4= (C10=0.056, C11=0.024)T and W5= (C12=0.14, C13=0.14)T. The
comprehensive evaluation results of the equipment in use were as follows: AS128 CT>E9 color ultrasound>DSA>1.6T MRI>
mammography target>high frequency hyperthermia machine>photon radio frequency instrument. Conclusion Combined with the
comprehensive application of the two methods, it is more scientific, reasonable and applicable for the comprehensive evaluation of
the use efficiency of the equipment.
