A Digital-Twin-Enabled AI-Driven Adaptive Planning Platform for Sustainable and Reliable Manufacturing
This study introduces a novel AI-driven adaptive planning platform combining Digital Twin (DT) technology with a Pareto-conditioned Multi-Objective Proximal Policy Optimization (MO-PPO) algorithm. The platform aims to co-optimize operational reliability and environmental sustainability in real-time manufacturing, addressing market instability, sustainability policies, and aging equipment. It formulates manufacturing planning as a Constrained Multi-Objective Markov Decision Process (CMDP), optimizing Overall Equipment Effectiveness (OEE), energy carbon intensity, and material waste, while adhering to operational constraints. Empirical testing through 10,000 simulations and a 12-week industrial pilot demonstrated statistically significant improvements in schedule performance, OEE, energy usage, material waste, and carbon effectiveness, outperforming all baseline strategies. The research also revealed a surprising synergistic correlation between waste minimization and OEE enhancement, indicating that sustainability strategies can contribute significantly to reliability.

AI-Driven Adaptive Planning
The platform reinvents manufacturing planning as a Constrained Multi-Objective Markov Decision Process (CMDP), optimizing OEE, energy carbon intensity, and material waste while adhering to operational restrictions. This allows for real-time adjustments to market instability, sustainability policies, and equipment status.
Digital Twin (DT) Integration
A physics-based Digital Twin (DT) provides a high-fidelity stochastic training environment for the MO-PPO agent. It includes sub-models for processing times, machine degradation, quality propagation, and state-dependent energy consumption, calibrated via Bayesian inference to minimize simulation-to-reality gaps.
Multi-Objective Reinforcement Learning (MORL)
A Pareto-conditioned Multi-Objective Proximal Policy Optimization (MO-PPO) algorithm is at the core, allowing co-optimization of reliability and sustainability indicators. It introduces innovations like preference-conditioned actors, multi-head critics, Pareto experience replay, and curriculum training to ensure sample-efficient learning and stable, constraint-satisfying policies.
