Multi-objective optimization for backpressure forming of thin-walled complex scrolls via a hybrid PSO-BPNN, NSGA-III, and TOPSIS framework

Backpressure forming is essential for precision forming of thin-walled complex scrolls by applying a controllable counter-pressure to regulate inhomogeneous material flow. However, the process involves strong thermo-mechanical coupling effects, and there exists a highly nonlinear...

Optimization of Multimodal Public Transit Networks Considering Spatial Equity

Public transport equity is usually assessed after a network has been designed rather than treated as a requirement that shapes the design itself. This study develops an equity-oriented optimization framework for hierarchical multimodal transit networks in which a fixed rail backb...
