CNRS N° 7554, University... of the most important purposes for offshore structure researchers is to maintain the structural integrity of these structures, which means to make an initial prediction about the safety......
features of this algorithm is its ability to determine the critical condition of failure wedges, the minimum safety factor and maximum force acting on the wall, as well as the minimum weight... and minimizes the safety factor for wall stability. The results obtained in this study are in good agreement with those of similar studies carried out based on the limit equilibrium method and finite......
comprehensive theory model for the safety evaluation of a mine ventilation system. They took advantage of artificial neural network and fuzzy control theory to assess credibility levels. The assessment results... a safety assessment of a petrochemical enterprise and quality evaluation of Chinese red wine based on the calculation of CS. In their study, the CS was calculated by cloud descriptors. The calculation......

-extenics model to safety evaluation of rock slope stability WANG Xinmin1, KANG Qian1, QIN Jianchun1, 2, ZHANG Qinli1, WANG Shi1 (1. School of Resources and Safety Engineering, Central South University..., thus the slope stability was evaluated and the safety level standard and the evaluation index were obtained. Firstly, the weight vector about the safety index was determined by AHP which influenced......
and accidents was firstly conducted. Then, the evaluation model of traffic safety was developed. Based on this model and correction factors of variables, the risk identification model and the risk... accident rate agrees well with the actual accident rate, and thus the proposed risk evaluation system can guide the safety management of hazardous chemicals transportation on similar freeways. Key......
