Adaptive Lagrangian Penalty-Enhanced Proximal Policy Optimization for Flexible Job Shop Rescheduling with Worker Workload Constraints Under Concurrent Dynamic Disturbances

When flexible job shop scheduling faces concurrent disturbances such as machine failures and rush orders, worker-centric constraints emphasized under Industry 5.0 must also be satisfied. Existing deep reinforcement learning methods for the Dynamic Flexible Job Shop Scheduling Pro...

Insights into Early-Age Interfacial Bonding Improvement of Polymer-Modified Sulfoaluminate Cement Mortar: Roles of Polymer Film Formation and Hydration Regulation

In this study, a polymer-modified fast-hardening and early-strength cement-based repair material was proposed, using the polymer cellulose ether (HPMC), polymer dispersible polymer powder (VAE) and silica fume. The optimal mixing ratio of the three polymers was designed by an ort...
