Therefore, this paper first investigates the energy efficient dynamic flexible job shop scheduling problem with machine breakdowns. To solve this problem, a knowledge-guided evolutionary algorithm incorporating reinforcement learning (KEARL) is established to minimize maximum completion time, total energy consumption, and workload of critical machines, which is a mixed-integer linear programming model with transportation time of jobs and setup time of machines included. In KEARL, a new rescheduling strategy is designed to reduce the possibility of the machine's second breakdown. In addition, four knowledge-guided initialization methods are also designed and a reinforcement learning-based parameter adaptive strategy is used to optimize the crossover probability and mutation probability, while a knowledge-guided variable neighborhood search strategy enhances the search capability of KEARL. More importantly, three energy efficient methods are implemented to reduce the energy consumption of the production process. Finally, through extensive experiments, the KEARL is compared with several well-known algorithms.

To mitigate these issues, multiple task assignment schemes with high interchangeability are required, each tailored to one specific scenario. However, the resulting mixed-model two-sided assembly line balancing problem considering PM scenarios (MTALBP-PM) has not been studied. Therefore, a mixed-integer linear programming model is formulated to minimize total cycle time and task adjustment simultaneously.

Concretely, with the guidance of problem-specific knowledge, a decoding mechanism and three objective-oriented neighborhood structures are designed to achieve solutions with better objectives. Using unsupervised learning, an initialization heuristic is mined from tacit information to obtain high-quality initial solutions. With historical search information, a self-adaptive strategy based on Q-learning is proposed to recommend the best-fit neighborhood structure for higher efficiency. Besides, an auto-tuning restart operator based on multi-domain knowledge is employed to escape local optima.

These make most of them have the low search efficiency and behave unsatisfactorily. For this purpose, this work develops a dual ensemble-surrogate assisted evolutionary algorithm with state information driven infill criterion (SIDSAEA) for expensive many-objective optimization. In SIDSAEA, two ensemble-surrogate models are built based on the same really evaluated training set for fully exploiting the information in the real objective evaluations, where one is to approximate the objective functions for optimizing and the other is to approximate the proposed comprehensive performance indicator for infilling. Based on the model for objective functions, an inner–outer region based dominance relation is designed to select a promising population, and further improve the algorithm search efficiency. In addition, a state information driven infill criterion is proposed to select the optimal individuals for updating the model. According to the captured state, this criterion adaptively switches between the expected improvement based on the above performance indicator and the uncertainty of approximating objectives, and thus better balances convergence and diversity of individuals and improves the algorithm exploration.

Moreover, an adaptive stop-update strategy is designed.
