Leveraging Transfer Learning in Deep Reinforcement Learning for Solving Combinatorial Optimization Problems Under Uncertainty

Autor: Fatima Ezzahra Achamrah

Publikováno v: IEEE Access, Vol 12, Pp 181477-181497 (2024)

In recent years, addressing the inherent uncertainties within Combinatorial Optimization Problems (COPs) reveals the limitations of traditional optimization methods. Although these methods are often effective in deterministic settings, they may lack

Spare Parts Inventory Routing Problem with Transshipment and Substitutions Under Stochastic Demands

Autor: Sabine Limbourg, Fatima Ezzahra Achamrah, Fouad Riane

Publikováno v: Applied Mathematical Modelling
Applied Mathematical Modelling, Elsevier, 2021, ⟨10.1016/j.apm.2021.08.029⟩

We study a two-level spare parts supply chain in which a manufacturer supplies a central warehouse (CW) with original equipment manufacturer (OEM) and replacement or pattern parts (PP). The CW, distantly located from the manufacturer, distributes bot

An Artificial-Immune-System-Based Algorithm Enhanced with Deep Reinforcement Learning for Solving Returnable Transport Item Problems

Autor: Fatima Ezzahra Achamrah, Fouad Riane, Evren Sahin, Sabine Limbourg

Publikováno v: Sustainability; Volume 14; Issue 10; Pages: 5805

This paper proposes a new approach, i.e., virtual pooling, for optimising returnable transport item (RTI) flows in a two-level closed-loop supply chain. The supply chain comprises a set of suppliers delivering their products loaded on RTIs to a set o
