A Pipeline Soil Corrosion Comprehensive Prediction Method Using Multi-Method Integration

Special Issues Editor (Nottingham Tent University, United Kingdom (Great Britain))

In order to improve the prediction evaluation method accuracy of the pipeline soil corrosion, identified the core indicators in different geological conditions in the light of the pipeline soil corrosion characteristics and increased the adaptability to the environment, established the decision table to the original soil corrosion data of multi-factors and indexes by the rough set approach, then simplified it and extracted the core index. Brought out the core multi-factors and indexes with the set pair theory by the integrated use of a specific connection degree mathematical model, determined the index weight and improved the prediction model accuracy by means of the entropy method, calculated the distance of the contact degree between the forecast system to test and the classification system on the contrary identical discrepancy model according to choosing the nearly principle in the clustering analysis thought, thereby carried out the multi-factor comprehensive prediction. Set Liang ping section of the East gas pipeline in Sichuan as an example, through the above model, the predicted evaluation results conform to the actual situation. It provides a methodological guidance for the region soil corrosion comprehensive prediction.
