With the dawn of Industry 5.0 upon us, smart factory emerges as a pivotal element, playing crucial role in realm intelligent manufacturing. Meanwhile, mobile edge computing is proposed to alleviate computational burden presented by substantial workloads factories. Nonetheless, it very challenging effectively incorporate resources improve efficiency resource deployment Accordingly, we devise novel approach based on Proximal Policy Optimization algorithm with Self-Attention Mechanism implement allocation MEC-Empowered Smart Factories. More specifically, self-attention mechanism incorporated enable dynamic focus state information, accelerates convergence and facilitates global control. A great number experiments conducted both simulated real datasets have verified superiority our compared state-of-the-art baselines.

In today’s customer-centric economy, the demand for personalized products has compelled corporations to develop manufacturing processes that are more flexible, efficient, and cost-effective. Flexible job shops offer organizations agility cost-efficiency traditional lack. However, dynamics of modern manufacturing, including machine breakdown new order arrivals, introduce unpredictability complexity. This study investigates multiplicity dynamic flexible shop scheduling problem (MDFJSP) with arrivals. To address this problem, we incorporate fluid model propose a randomized adaptive search (FRAS) algorithm, comprising construction phase local phase. Firstly, in phase, heuristic an online tracking policy generates high-quality initial solutions. Secondly, employ improved tabu procedure enhance efficiency solution space, incorporating symmetry considerations. The results numerical experiments demonstrate superior effectiveness FRAS algorithm solving MDFJSP when compared other algorithms. Specifically, proposed demonstrates quality relative existing algorithms, average improvement 29.90%; exhibits acceleration speed, increase 1.95%.
