MetaGradient driven strategy decomposition for accelerated equilibrium in large scale logistics networks
Dandan Wang, Ni Sun
TL;DR
This paper introduces a new optimization framework that improves efficiency and reduces emissions in large logistics networks by achieving faster equilibrium and better resource utilization.
Contribution
The novel contribution is a gradient-driven framework combining sparse gradient, tensor decomposition, and constrained multi-objective optimization for real-time logistics optimization.
Findings
The framework reduces costs by 28.3%, transit time by 37.3%, and CO₂ emissions by 27.7%.
It achieves a capacity matching degree of 89.3% with a root mean square error of 0.145 in a 15-node network.
The method enables sub-second equilibrium convergence and anti-disturbance recovery in large-scale logistics.
Abstract
Static models fail to track the fast-changing supply-demand balance in global logistics. For instance, the high-speed rail express corridor exhibits a transport capacity utilisation rate of less than 70% during peak periods, along with a node load imbalance of 0.57. Existing algorithms have been shown to exhibit a 7.8% prediction error and 38% convergence time overruns during sudden demand changes. This study proposes a gradient-driven framework that combines sparse gradient, tensor decomposition, and constrained multi-objective optimization. Cost drops 28.3%, transit time shrinks 37.3%, container turnover rises 41.4%, and CO₂ falls 27.7%. In the 15-node network, the framework achieves a capacity matching degree of 89.3% with a root mean square error of 0.145, which is better than the benchmark performance of traditional methods and reinforcement learning methods.
