Efficient Data-Driven Leverage Score Sampling Algorithm for the Minimum Volume Covering Ellipsoid Problem in Big Data
Elizabeth Harris, Ali Eshragh, Bishnu Lamichhane +2
The Minimum Volume Covering Ellipsoid (MVCE) problem, characterised by observations in dimensions where , can be computationally very expensive in the big data reg…
A Modified Algorithm for Optimal Picker Routing in a Single Block Warehouse
George Dunn, Hadi Charkhgard, Ali Eshragh +1
The order picker routing problem involves finding the optimal tour of a warehouse that collects all the required items on a given pick list. Ratliff and Rosenthal introduced a dyna…
Deep Reinforcement Learning for Dynamic Order Picking in Warehouse Operations
Sasan Mahmoudinazlou, Abhay Sobhanan, Hadi Charkhgard +2
Order picking is a pivotal operation in warehouses that directly impacts overall efficiency and profitability. This study addresses the dynamic order picking problem, a significant…
Optimal Experimental Design for Partially Observable Pure Birth Processes
Ali Eshragh, Matthew P. Skerritt, Bruno Salvy +1
We develop an efficient algorithm to find optimal observation times by maximizing the Fisher information for the birth rate of a partially observable pure birth process involving $…
Deep Reinforcement Learning for Picker Routing Problem in Warehousing
George Dunn, Hadi Charkhgard, Ali Eshragh +2
Order Picker Routing is a critical issue in Warehouse Operations Management. Due to the complexity of the problem and the need for quick solutions, suboptimal algorithms are freque…
