Failure possibility evaluation on pipeline in use based on rough set
Wei Wang · Journal of Xi'an University of Science and Technology · 2007
The safety of the pipeline in use is linked with that of resident life and belongings.Making the research on oil and gas pipeline system,this paper puts forward nine primary factors,including the depth earthed up pipeline,public education,damage by outside force,operation management etc.,that may impact pipeline failure,and sets up four grades on failure consequence according to the loss of failure,determines weight coefficient by analyzing main case of pipeline failure based on rough set theory and analytic hierarchy process. Then,the paper draws some conclusions such as enhancing management,optimizing design,improving construction quality,strengthening public education etc.,and makes them the main channel for preventing pipeline from failure.
