Abstract: Based on the study of the practical problems in hydraulic analysis of natural gas network,this paper has not only come up with a concept of Grey Optimization,but also established a kind of model with non-linear grey optimization.This model will be applied to solve some problems of multiple non-linear equations.By use of computer,the results show that this method is efficient and is also of certain theoretic and practical significance.
