A Fuzzy Inference Algorithm Suitable for Road Network Weight Analysis in Mountain Areas

This paper introduces a fuzzy quantitative analysis method that is comprehensive consideration of terrain,road grade,length,slope,curvature and other impact factors to determine the weight values of the road link based on theory of fuzzy inference and expert knowledge,which makes up for the ignorance of lack of spatial geographic information.Because knowledge and expert knowledge are universal in the world,the method can be applied to other areas.The way of fuzzy inference is applied to coal-bed gas surface gathering system of Shizhuang demonstration area in the southern of Qinshui Basin,which can meet the needs of the daily patrol decision-making.Practice shows that this study has some practical value.
