Abstract: The LNG vehicles industry is an emerging vehicles industry，and the feasibility study and evaluation of the development
of LNG vehicles industry is its premise and basis for popularizing this industry. Feasibility evaluation results can
be provided for the governments or enterprises，for their decision making concerned the development of LNG vehicles industry.
This article analyzes the feasibility of developing LNG vehicles industry from technical，economic，environmental
and resources protection capacity，structures the feasibility index system of LNG vehicles industry development，puts forward
specific methods for developing LNG vehicles industry using multi-layer fuzzy comprehensive evaluation by establishing
reasonable set of factors，evaluations，or weight sets and so on，and uses examples to do specific calculations and analysis
application. The feasibility of LNG vehicles industry developing by using multi-layer fuzzy comprehensive evaluation is very
good，and popularization and application of the LNG vehicles is quite feasible.

Key words: LNG vehicles, industry, feasibility, fuzzy analysis
