ABSTRACT: Vehicle Routing Problem (VRP) is considered as the most challenging combinatorial optimization problems. Typically, VRP models do not consider the most important factor determining the success of the VRP plan; which is the human factor. Therefore, this presentation will discuss a VRP model that shows how to measure the influence of driver behavior on the optimal VRP plan. The level of autonomy of making logistical decisions such as speed or route changing decisions for both planner and drivers have been represented in the model by involving risk taking parameters. Also, the effect of changing the level of autonomy on the VRP total costs has been investigated using a sensitivity analysis. Accounting for the driver autonomy ensures that the driver can make decisions on time when unexpected conditions are emerged. Also, for the purpose of ensuring environmental friendly logistical practices, the policy of velocity maximization has been used as well as imposing environmental penalties on the chosen rate of velocity associated with certain fuel consumption rate. It additionally accounts for the consumed energy during serving customers in order to optimize the service time. A numerical instance with a hypothetical data set has been solved by the Intra-route neighborhood heuristic. The results justify that considering the differences among drivers does not affect optimal plan negatively, vice-versa, the expected benefits on the environment, economy, and society are magnified.


Bio: Mohammed Othman is an Assistant Professor in the Industrial Engineering Department, Coordinator of Master of Engineering Management and Head of the Department of Industrial Engineering at An-Najah National University, West Bank, Palestine. He received his bachelor’s degree in Industrial Engineering from An-Najah National University, Palestine in 2002. Then, he received his M.A.Sc. degree in Industrial Engineering from Concordia University, Montreal, QC, Canada in 2008 and PhD in Industrial Engineering from Concordia University, Canada, in 2012. His research interests include product design and development, production planning and scheduling, human factors, operations research, and logistics management. His research efforts focus on the development of mathematical models for the integration of drivers’ differences into smart and green waste collection Vehicle Routing Problem (VRP). His most recent research explores the effect of the driver’s behavior on the optimal VRP plan by integrating the level of autonomy of both planner and drivers as represented by risk-taking parameters. In these areas, Dr. Othman has published 15 articles in technical journals, and international conferences. He has supervised more than 15 master thesis and acted as an examiner for more than 20 master theses since 2014. He can be contacted at m_othman@najah.edu
