A recovery mathematical model for the impact of supply chain interruptions during the lockdown in COVID-19 using two warehouse perishable inventory policies

This study develops an inventory model for things that deteriorate at a rate that depends on time.The research work is about minimizing the JOOVA CREAM total cost of a two-warehouse system during the lockdown period.We consider two scenarios and the LIFO policy has been used in this model.In the first scenario, the stocks of the rented warehouse (R

Exploration Degree Bias: The Hidden Influence of Node Degree in Graph Neural Network-Based Reinforcement Learning

Graph Neural Networks (GNNs) have demonstrated remarkable performance in tasks involving graph-structured data, but they also exhibit biases linked to node degrees.This paper explores a specific manifestation of such bias, termed Exploration Degree Bias (EDB), in the context of Reinforcement Learning (RL).We show that EDB arises from the inherent d
