Abstract	For the risk of remanufacturing arm structure with multi-coupling defects and the correlation and influence between risks factors, the jib structure risk evaluation theory based on improved DEMATEL method (JSRET-IDM) is presented to build a risk assessment model for jib structure in accordance with potential failure modes and to develop a risk assessment system of remanufacturing jib structures for mobile crane. Failure performance datum of jib structure in service being collected, researched, and analyzed, the mechanical property, notch-crack and welding performance are backdated under characteristic parameters and typical service conditions to set up the failure modes database. Testing positions and points can be determined according to the database. The direct and indirect influence fuzzy relation matrixes between testing points or evaluation indexes are established by IDM to deduce influence matrixes and affected matrixes of every evaluation index, aiming at obtaining the centrality and reason degree being used to determine weighting factor of each index based upon making an analysis of the correlation and influence of the indexes. Accordingly, combined with FSET, the failure risk can be easily quantified. Using it as a base, the risk system is developed to realize the real-time, accurate and rapid assessment of the failure risk for jib structure. Taking QY130 remanufacturing arm structure as an example, the effectiveness and scientificity of the proposed method and system are verified.
