*: Equal contribution, ✉: Corresponding authorThis paper investigates intelligent configuration management for modular production systems by integrating operational semantics with knowledge graph representations. The proposed approach formalizes configuration knowledge and system behavior through operational semantics, enabling consistent reasoning across modular components.

The coexistence of manual and autonomous driving leads to nonstandard final parking states (FPS) of adjacent vehicles, which can hinder passenger door access if a standard FPS is enforced for the target vehicle. To enhance passenger comfort during boarding and alighting, this paper proposes an efficient bidirectional search hybrid A* (BHA*) method for parking path planning under adjacent vehicle deviation scenarios. A characterization variable for passenger comfort is constructed based on allowable and required door opening angles under adjacent vehicle constraints. An optimization model for the FPS is established with a comprehensive objective that balances passenger comfort for both target and adjacent vehicles while ensuring safe distances. A genetic algorithm is employed to determine the optimal FPS, and Voronoi potential fields combined with a bidirectional search strategy are used to generate feasible and comfortable parking paths. Experimental results demonstrate that the proposed BHA* method effectively improves parking feasibility and passenger comfort in complex parking environments.
Industry 4.0 demands intelligent and autonomous manufacturing systems that can adapt to dynamic and uncertain environments. A key enabler of such systems is self-learning, which supports effective decision-making under uncertainty. However, conventional approaches typically rely on large volumes of physical production data, limiting their applicability during early deployment phases. To address this challenge, this paper proposes a digital twin-based self-learning decision-making framework that enables virtual training and validation of decision models prior to physical deployment. The framework comprises four modular components: a digital twin for simulating the production environment, a learning module for generating and evaluating decisions, a real controller for executing validated actions, and the physical production system. A time-delayed deployment mechanism is introduced to ensure the safe transfer of learned behaviors from the virtual environment to real-world operation. Experimental results demonstrate that the proposed framework enhances decision quality, adaptability, and deployment efficiency for industrial robotic systems.
In automatic parking scenarios, obstacles on both sides of a target parking space can significantly degrade the feasibility and comfort of passenger boarding and alighting (CPBA) when a standard final parking state is maintained. Moreover, the presence of dynamic obstacle vehicles in parking lots poses substantial challenges to the adaptability of path-planning algorithms. To address these issues, this paper proposes a method for final parking state optimization and two-stage path planning in dynamic parking environments while explicitly considering CPBA. A CPBA characterization variable is first constructed based on the allowable opening angle of the vehicle door constrained by adjacent obstacles. To improve path quality, the basic motion curve of the vehicle is formulated to support queuing, parking, and transition maneuvers. A two-stage path planning framework is then developed to integrate parking lot system-level planning with vehicle-level trajectory generation, enabling safe, adaptive, and comfort-oriented automatic parking in dynamic scenarios. Experimental results demonstrate the effectiveness of the proposed approach in enhancing parking feasibility, adaptability, and passenger comfort.
