          報告人:   司徒惠源 教授




          司徒惠源教授長期從事交通網絡設計問題、交通網絡不確定性和可靠性、綠色交通、公共自行車交通、動態交通分配問題、智能交通系統、公共交通、優化算法等領域的研究。先后在國際SCI或SSCI檢索刊物上錄用或發表論文130余篇,2篇發表在管理科學與運籌學領域頂級期刊《Operations Research》上,30余篇發表在交通科學頂級期刊《Transportation ResearchPart B》上,5篇論文在交通科學頂級國際會議ISTTT上宣讀,其他論文主要發表在《Transportation Research Part A》、《TransportationResearch Part C》、《Transportation Research Part D》、《TransportationResearch Part E》等SCI國際刊物上。司徒惠源教授現擔任《Transportmetrica B》和《Open Engineering》的編輯,《Networksand Spatial Economics》和《International Journal of Transportation》等國際期刊的區域編輯;并擔任《Journal of Intelligent Transportation Systems》、《TransportmetricaA》等國際期刊的副主編;還擔任《Transportation Research Part B》、《Networksand Spatial Economics》等8個國際期刊的客座編輯,以及《Transportation ResearchPart C》、《Transportation Research Part D》、《TransportationResearch Part E》等8個國際期刊的編委。


          Multiple taxi types withdifferent service areas exist in practice. However, to the best of ourknowledge, there is no methodology to determine the best service region of eachtype of restricted area taxi in a taxi market. It is also unclear what thedeterminant factors are for the design. This study proposes a nonlinear mixedinteger programming model to determine the service areas. The objective is tomaximize social welfare. A greedy heuristic is developed to solve the model. Numericalexamples are given to show the performance of the heuristic and the determinantfactors for the design.
