Construction Safety Risks of Metro Tunnels Constructed by the Mining Method in Wuhan City, China: A Structural Equation Model-Fuzzy Cognitive Map Hybrid Method
نویسندگان
چکیده
A hybrid method based on the structural equation model (SEM) and a fuzzy cognitive map (FCM) was developed to study influences of construction safety risks (CSR) metro tunnels constructed by mining project risk (PR). An SEM used identify verify correlations between CSR PR. FCM adopting verified standardized causality path coefficient in SEM. On this basis, predictive reasoning diagnostic were performed framework an simulate The feasibility validated tunnel Wuhan City, China. results show that (1) cause concept node C2 (tunnel excavation) shows strongest positive correlation with target CT According their risks, stages are ranked descending order as excavation), C1 (advanced support), C6 (auxiliary measures), C4 (structure waterproofing), C3 (primary C5 (secondary lining). (2) is most sensitive changes nodes C1. (3) Close attention should be paid key such X9 (over-excavation under-excavation) X8 (unreasonable determination excavation footage sequence) stage C2. Originality significance: can dynamic interaction PR proposed. new perspective for evaluation provided. decision-making tool controlling

A hybrid method to construct Fuzzy Cognitive Map
This paper presents a hybrid methodology of automatically constructing fuzzy cognitive map (FCM). The proposed method is based on immune algorithm to learn the connection matrix of FCM. In the algorithm, the DNA coding method is used, and in order to utilize the experts’ knowledge and the feature of system, they are used as “vaccine”. Finally, an illustrative example is provided. The results su...
