Prof.dr. W.E. (Warren) Walker


Warren E. Walker is an emeritus Professor of Policy Analysis in the faculty of Technology, Policy and Management at Delft University of Technology. He has a Ph.D. in Operations Research from Cornell University, and more than 40 years of experience as an analyst and project leader at the RAND Corporation, applying quantitative analysis to public policy problems at the local, regional, national, and international levels.

His recent research has focused on methods for dealing with deep uncertainty in making public policies (especially with respect to climate change), improving the freight transport system in the Netherlands, and the design of decision support systems for airport strategic planning. 

He has led several large policy studies for the Netherlands Ministry of Transport, Public Works and Water Management, most of which have involved cost-effectiveness analyses of complex problems with multiple stakeholders in which a range of impacts of alternative policies are assessed and tradeoffs are made among the environmental, economic, and social impacts.

He has been a special advisor to the Director for Freight Policy in the Netherlands Ministry of Transport, Public Works and Water Management, and has carried out strategic planning studies for that Directorate. He was a member of the Scientific Committee of a project for the European Commission that helped to design a European Transportation  Information System (ETIS). He is the recipient of the 1997 President’s Award from the Institute for Operations Research and the Management Sciences (INFORMS) for his "contributions to the welfare of society through quantitative analysis of governmental policy problems."
