Study on Comprehensive Evaluation of Elevator Door System Based on AHP-CRTIC
Abstract
The elevator door system is affected by the physical structure, external factors and geographical location and other factors, and has become the most prone to failure and accident components in the eight elevator systems. Select 15 evaluation factors including speed, acceleration, operating noise, vibration frequency and response time in the transmission system; voltage, current, corrosive gas, conductive dust in the safety protection system, engagement depth, leveling accuracy, temperature, humidity, balance coefficient and load weight in the stripping system, calculate the subjective and objective weight of each evaluation factor by AHP and CRTIC evaluation method, establish the AHP-CRTIC comprehensive evaluation model. Compared with the evaluation results of AHP, C RTIC and AHP-CRITIC models in the actual elevator system, the results show that the evaluation accuracy of combined empowerment is the highest, which provides a new idea and method for the safety performance evaluation of the elevator door system.
