This paper presents a gray-level analysis approach of the feature item weight calculation based on the multi-experts. This method increases gray character of the parameters and the processing capacity of multi-experts to the regular Analytic Hierarchy Process (AHP). It gives a scale interval gray number when the experts determine the scale value, tectonic multi-experts gray determine matrix. Through the whitening algorithm of gray matrix and consistency inspection it determines the feature weights. Compared with the traditional AHP algorithm, the proposed algorithm is more in line with people's cognition rule, to more people with cognitive laws and the actual, has certain application value. Finally, making the case feature weights calculation in the railway rescues command system as an example to analyze the result, verifies the validity of the method in the paper.
