1. use feature of the present invention is:

  • gather the inner self attributes of old city feedwater piping and external influence factors two class basic data information and input computing machine;

    In conjunction with inner self attributes information such as the feedwater piping comprising caliber, pipe range, tubing, pipe age, resistance coefficient and node flow etc., set up feedwater piping hydraulic analysis model, obtain feedwater piping waterpower service data;

    In conjunction with the external influence factors comprising water quality situation etc. in geologic condition, buried depth of pipeline, traffic flow loads, executive cost, corrosive pipeline situation and pipeline, set up feedwater piping external influence factors weight model based on gray theory, give different weight to external influence factors;

    Based on above-mentioned hydraulic analysis model and external influence factors weight model, set up feedwater piping threat level assessment model, and the danger classes of feedwater piping is divided into slight, medium, serious and urgent four grades;

    Utilize improved adaptive GA-IAGA to solve above-mentioned feedwater piping threat level assessment model, assess the transformation order of old city feedwater piping.
