Safety Evaluation of Gantry Crane Based on Entropy-Fuzzy Comprehensive Evaluation Model

Aiming at giving the accurate value of risk assessment and the level of gantry crane in risk management. Firstly, this paper use relationship diagraph to generalize and analyze four different aspects-People, Machine, Management, Environment. Secondly, a new model named "Entropy-Fuzzy Comprehensive Evaluation Model" can be constructed which combines a safety assessment method (multivariate risk evaluation) with a coefficient resulting from Entropy Method (EM) to avoid the uncertainty in Gantry Crane. By following, when it comes to the reaction between different factors, there are distinguished levels of safety problems. Therefore, from the four aspects mentioned above to estimate the possibilities of accident, the new constructed model (EFCEM) is one of the methods to make managing and controlling the problems of Gantry Crane's safety in different levels comes true. At last, a specific verification of Gantry Crane taken advantage of demonstrates that the new model is viable from the perspective of safety assessments and solutions.
