主題一：Emergency supplies distribution for early response operations under demand information asymmetry
主講人：舒嘉，電子科技大學經管學院教授
摘要：Quick distribution of emergency supplies to satisfy the urgent demands in the affected areas after a disaster is of crucial importance in mitigating its impact. Because the response actions must be carried out before the demand information is fully realized upon a disaster attack, in this paper, we investigate the inbound emergency supplies distribution for early disaster response operations under demand information asymmetry. The problem naturally falls into a two-stage modelling framework, in which the first stage focuses on the early response operations of emergency supplies distribution before the actual demand information is realized in the second stage. We cast the problem as a two-stage robust model, for which we derive two deterministic equivalents, i.e., a linear programming (LP) equivalence and a mixed-integer programming (MIP) equivalence (with a polynomial size). We illustrate the advantage of the two-stage robust model in comparison with the corresponding non-early response model and two-stage stochastic model by a case study concerning the 2010 Yushu earthquake in PR China. Computational results also demonstrate that the MIP equivalence of the robust model can solve random instances with larger scales very efficiently.

主題二：Research progress in transportation operations.
主講人：李志純，華中科技大學教授、博導
摘要：The investment in transportation infrastructure may cause changes of urban form and urban economic development. Conversely, the urban economic development can cause a change in the travel demand. The interaction between them will create a new urban system equilibrium. This talk will present the recent research progress in the fields of Transportation Economics. Advanced research methods and some new insightful findings are reported.
