Prediction of Remaining Life of City Gas Pipelines Based on Decision Tree Classification Algorithm

City gas pipelines play a very important role in ensuring urban energy supply, but there is a problem that the remaining life of pipelines is not satisfactory. Traditional evaluation methods cannot solve the problem of predicting the remaining life of city gas pipelines, and the prediction is inaccurate. Therefore, a decision tree classification algorithm is proposed to predict the remaining life of urban gas pipelines. Firstly, the simulation theory is used to accurately predict the remaining life of the gas pipeline, and the maintenance and replacement are carried out according to the requirements of safe operation and treatment, to reduce the city gas pipeline Security risks. Then, the simulation theory constructs a prediction model for the remaining life of urban gas pipelines, forms a safe operation treatment scheme, and predicts the remaining life of urban gas pipelines Conduct a comprehensive analysis. MATLAB simulation shows that the decision tree classification algorithm predicts the accuracy of the remaining life prediction of city gas pipelines and the city gas pipelines under certain processing criteria The remaining life prediction time is better than traditional evaluation methods.
