Performance Evaluaiton of Measuring Instruments Based on Fuzzy Comprehensive Evaluation

In order to make better use of the instruments in the laboratory, the fuzzy compreh-ensive evaluation based on entropy weight method is selected to evaluate the function of the measuring instrument, so as to judge whether the instrument in the laboratory has reached the end of life and improve the utilization of the instrument. Rate and reduce unnecessary losses. Five indicators for judging the quality of the instrument were selected, and their weights were determined according to the entropy weight method to establish a fuzzy comprehensive evalu-ation model. This method is used to judge the experimental equipment of the equal-thickness interference image of light, and the evaluation of the device is “excellent”, which verifies the feasibility of the model.
