- Abstract
-
In this presentation, we develop a framework for routing and controlling the Automated Guided Vehicles (AGVs). As the AGV routing and control are done in real time, the framework requires the solutions to be generated very fast. To address this computational challenge, the solution framework consists of two stages. The first stage determines the rough routes of the AGVs. The second stage determine the detail routings and schedules of the AGVs. As solving the detail routings and schedules require high computing resource, we decompose the port layout into submodules where each of them can be solved almost independently. The output of the first stage (rough routes) becomes an input to the second stage which solve the detail routes and schedules for real time control. Whenever an AGV completes a task, the first stage will be called to revise the rough routes of the AGVs which includes the new task which is assigned to the AGV that has completed the previous task. The new rough routes will become input for second stage to solve the detail routes and schedules. We show this framework is promising and is able to generate the detail routes and schedules very fast.

Bio: Dr CHEW Ek Peng received his Ph.D. in Industrial Engineering from the Georgia Institute of Technology, USA. He is currently an Associate Professor in the Department of Industrial Systems Engineering and Management at the National University of Singapore. He also holds positions as the Deputy Head (Undergraduate Studies), Director for the Centre of Excellence in Modeling and Simulation for Next Generation Ports, and Co-Director for the Centre for Next Generation Logistics. He was a Visiting Scholar and a Visiting Professor, respectively, at the Georgia Institute of Technology and University of British Columbia in 2006. His current research areas are in port logistics and maritime transportation, simulation optimization and inventory management. Some of his research works are published in journals such as Transportation Science, IISE Transactions, European Journal of Operational Research, and Naval Research Logistics. He is serving as Editor-in-Chief of the Asia Pacific Journal of Operational Research, member of the Editorial Board Editors of the Transportation Research Part B, member in the Editorial of Flexible Services and Manufacturing Journal. He has also co-edited a book in “Advances in Maritime Logistics and Supply Chain Systems’, a special issue for OR Spectrum on “IT-based planning and control of seaport container terminals and freight transportation systems” and three special issues for Flexible Services and Manufacturing Journal on “Maritime Container Logistics and Onshore Transportation Systems (Part 1, Part 2 and Part 3)”. He and Dr. Lee Loo Hay has recently led a team of multidisciplinary researchers and experience practitioners to win the Next Generation Container Port Challenge with a grand prize of US$1 mil by proposing a revolutionary double-storey container terminal, called the SINGA port. He and Dr Lee has also recently secured two large grants from Singapore Maritime Institute and Industry Alignment Fund, ASTAR, with a total of SGD21 million to work on the digitalization of the next generation ports and warehousing systems.
