讲座题目:Optimization Modeling for Some Problems in Transportation






In this talk, I shall discuss two problems in transportation research: (I) traffic demand estimation in a star network and (II) GPS trajectory data segmentation for identifying business points. We propose mathematical models for the captured problems by adopting the entropy maximization approach. Numerical algorithms based on Newton’s methods are designed to solve the optimization problems. Simulation experiments are then given to demonstrate the effectiveness and efficiency of our methods.


Ching is a Professor in the Department of Mathematics at the University of Hong Kong. He obtained his B. Sc. and M. Phil. degrees in Mathematics and applied Mathematics from the University of Hong Kong. He then received his Ph.D. degree in Systems Engineering and Engineering Management from the Chinese University of Hong Kong. He has previously taught at the department of applied mathematics of Hong Kong Polytechnic University and also the department of mathematics of Hong Kong University of Science and Technology. Before joining his Alma Mater, he was a lecturer at the Faculty of Mathematical Studies of the University of Southampton, where he taught both graduate and undergraduate courses in operations research.
