Accurate prediction of the remaining useful life (RUL) of lithium-ion batteries is essential for operational safety and predictive maintenance. However, accurate RUL estimation from incomplete degradation trajectories remains challenging because of limited observable history, nonlinear capacity degradation, local fluct...

In steelmaking and continuous casting production processes, the operating time delay often occurs, which may lead to casting break or processing conflict so that the initial scheduling plan becomes unrealizable. It is more difficult to reschedule because of the multiple parallel machines in the whole production process...

Within the current steelmaking and continuous-casting (SCC) production, the growing differentiation in the production processes stemming from the product diversification, brings about great difficulties in solving the SCC scheduling problem, and decreases pitifully the possibility of ascertaining the duality gap which...

The U-shaped Disassembly Line Balancing Problem (UDLBP) is a challenging combinatorial optimization problem for which efficient solution approaches remain limited. This study proposes an efficient branch-bound-and-remember (BBR) algorithm that integrates a memory-based mechanism and U-shaped dominance rules to effectiv...

Remaining useful life (RUL) prediction is critical for improving reliability and supporting predictive maintenance in aero-engine systems. However, existing methods have limitations in jointly modeling the spatial correlations between multi-sensor signals and the temporal evolution characteristics of the degradation pr...
