An End-to-End Learning Approach for Solving Capacitated Location-Routing Problems

arXiv:2511.02525v2 Announce Type: replace Abstract: The capacitated location-routing problems (CLRPs) are classical problems in combinatorial optimization, which require simultaneously making location and routing decisions. In CLRPs, the complex constraints and the intricate relationships between various decisions make the problem challenging to solve. With the emergence of deep reinforcement learning (DRL), it has been extensively applied to address the vehicle routing problem and its variants, while the research related to CLRPs still needs to be explored. In this paper, we propose the DRL w

Why this matters
Why now

The continuous advancements in deep reinforcement learning (DRL) techniques are enabling their expansion into increasingly complex combinatorial optimization problems that were previously intractable or highly inefficient for traditional methods.

Why it’s important

Improving solutions for capacitated location-routing problems (CLRPs) can significantly optimize logistics, supply chains, and resource allocation, yielding substantial economic efficiencies and competitive advantages for entities that adopt these advanced AI methods.

What changes

The ability to solve complex CLRPs 'end-to-end' using DRL signifies a move away from heuristic or approximation methods towards more optimal, data-driven solutions, potentially redefining operational efficiency standards in various industries.
