Research on fire and explosion-proof elevator design based on RAHP-QFD

In the current society, the application of fire-fighting explosion-proof elevators is reflected in more and more scenarios, indicating that fire-fighting explosion-proof elevators have great development potential. In this paper, the rough analytic hierarchy process (RAHP) and the mass function development method (QFD) are used to study and analyze the design of large-load and low-energy fire-fighting explosion-proof elevators, and put forward design suggestions. Firstly, the user demand index was obtained through market research and other methods, and the weight value of each demand was calculated by using the RAHP method, and then the user demand was transformed into technical indicators and the quality house was established, and finally the quality house was analyzed and conclusions. The RAHP-QFD method can well combine the user's needs with the technical indicators, and can more intuitively reflect the relationship between the user's needs and the technical indicators. At the same time, the combination of the two methods can complement the shortcomings of the two methods as a strong basis for conclusions.
