Risk Assessment of Oil and Gas Pipeline Based on Vague Set-Weighted Set Pair Analysis Method

This study focuses on a risk assessment method for oil and gas pipelines. Oil pipelines are usually constructed in complex geological environment potentially dangerous. Risk is key step their safety management. Therefore, the present paper establishes indicator system as foundation, we propose to obtain quantitative result pipeline based set pair analysis (SPA) theory. For weight values of each process, this presents calculation vague sets Then, Yanchang oilfield was taken case verify feasibility method, final 2.911, which meant relatively safe. The could also level indicator, showing that conditions, extreme weather, public awareness were particularly unsafe, service time, deformation, ground activity, operation training unsafe. It expected provide reference
