Abstract: The number of international public–private partnership (PPP) projects has gradually increased with global infrastructure interconnections. These international projects incorporate high risks, and legal risk is one of the ...

Abstract: There has been a long debate on how to measure design productivity. Compared to construction productivity, design productivity is much more difficult to measure because design is an iterative and innovative process. Today, ...

Abstract: This paper develops a hybrid simulation approach that integrates a dynamic default tree (DFT) and discrete-time Bayesian network (DTBN) to support tunnel boring machine (TBM) performance prediction and diagnosis. A causal ...

Abstract: This paper develops a holistic simulation-based approach to determining reasonable strategies to limit the magnitude of ground settlement in shallow tunnel excavation. Simulation models are built to investigate and analyze ...

Abstract: Tunnels are generally built under trunk roads (where traffic conditions are complex and heavy) in order to share the load of urban road systems. The construction of tunnels has significant effects on the surrounding ...

Abstract: Improving aerodynamic performance with limited dimensions is becoming more important in the design of multirotor aircraft. Complex coupling interactions exist between the structural parameters and aerodynamic performance ...

Abstract: During the operation of tunnels, structural performance could inevitably degrade due to stochastic and adverse factors. To reduce the randomness and uncertainty of the tunnel operation, this paper provides a novel global ...

Abstract: This paper presents a systematic approach that incorporates structural equation modeling (SEM) and exploratory factor analysis (EFA) to perceive and verify causal-relationships and interactions between enablers and goals ...

Abstract: This paper develops a novel hybrid approach that integrates metamodeling, machine learning algorithms, and a variance decomposition technique to support global uncertainty and sensitivity (US) analysis under uncertainty. ...
