Our speaker Prof. Janny M.Y. LEUNG will share with us on "From Preparedness to Recovery: A Tri-level Programming Model for Disaster Relief Planning".

The past decade has witnessed major natural and man-made disasters all around the world. Practitioners have recognised that strategic location of depots and pre-positioning of inventory greatly facilitate the speed and efficiency of evacuation and/or delivering supplies in the crucial days immediately after disaster strikes.  This paper proposes a tri-level programming model for disaster preparedness planning. The top level addresses facility location and inventory pre-positioning decisions; the second level represents damage caused by the disaster, while the third level determines response and recovery decisions. We use an interdiction framework instead of a stochastic or chance-constrained model. This allows the extent of damage to be treated as a parameter to facilitate scenario exploration for decision-support. We develop an iterative dual-ascent solution approach. Computational results show that our approach is efficient. We also draw insights from the computational instances for helping disaster relief planning.

All are welcome and registration is not required.

Janny Leung obtained an S.B. degree in Applied Mathematics from Harvard, an M.A. in Mathematics from Oxford University and a Ph.D. in Operations Research from the Massachusetts Institute of Technology. Before returning to Hong Kong, she was a faculty member at Yale University and the University of Arizona. She has also held visiting positions at Cambridge, The Asia-Pacific Logistics Institute in Singapore, IBM Thomas J. Watson Research Center in USA and MIT.

Her research interests are in transportation logistics, urban informatics, humanitarian logistics, combinatorial optimization and operations research, having investigated problems in many areas including public transit scheduling, health care operations, procurement, production, distribution, facility layout, manpower planning and baseball scheduling. In Hong Kong, she has collaborated with several local companies in projects on container management, airline catering operations, mass-transit timetabling and integrated crew/vehicle scheduling. Her work has been published in Mathematical Programming, Management Science, Transportation Science, Production and Operations Management, Operations Research, IIE Transactions, Discrete Optimization, European Journal of Operational Research, Transportation Research (Part E) and other journals. Her research has been well supported by the Hong Kong Research Grants Council and the (US) National Science Foundation.
