On-Site Safety Uncertainties Assessment of Construction Based on Cloud Model and Fuzzy Sets Theory
Publication: ICCREM 2018: Innovative Technology and Intelligent Construction
ABSTRACT
Safety uncertainties widely exist in every phase of construction projects, especially during the on-site building stage. To identify different kinds of on-site safety uncertainties, a four-level analytic hierarchy process (AHP) model is proposed based on China’s current construction industry standards. Then analyze the influence and frequency of level-4th (L4) factors, synthesized cloud model (SCM) is applied to sampling calculation program, with which both randomness and fuzziness can be jointly considered. Finally, a multi-factor assessment method (MAM) under fuzzy sets theory is used to assess level-3rd (L3), level-2nd (L2), and level-1st (L1) factors of on-site safety system. Such methodology not only avoids the limitation of filling in huge numbers of written documents, but also can realize the dynamic adjustment of system factors, and may significantly decrease the difficulty of on-site safety management and safety inspection. In addition, practical advices are put forward to avoid some limitations of standard.
