A large-scale construction or infrastructure project is very complex and has highly dynamic and interdependent risks and uncertainties over its long-term project life. This leads to the increasing challenges for an accurate project investment analysis and a right contractor selection. An Investment and Contractor Selection Decision Support System: Private-Public Partnerships Infrastructure Project Procurement provides the framework and methods of risk assessment and decision analysis designed to overcome the challenges. It covers the following features: 1. It highlights the debates of public-private partnerships infrastructure project procurement; 2. It addresses the critical issues of cost and benefit analysis; 3. It provides a modeling and simulation approach and statistical analysis to evaluating the effect of risk interdependencies; 4. It provides a method to project investment analysis integrating non-financial with financial evaluations; 5. It provides a stochastic analysis-based decision-making approach for project contractor performance comparison and selection; 6. It provides a risk and resource allocation method for project contract design.Dr. Jang has Ph.D. degrees and industry experiences in project engineering and management. His research interests considerably overlap between project Management, procurement management and operations research. His recent publications focused on modeling and simulation to assessing risk interaction effects on the large-scale project performance.
