Proceedings of 8th Annual London Business Research Conference Imperial College, London, UK, 8 - 9 July, 2013, ISBN: 978-1-922069-28-3 Real Options Methods for Evaluating International Railway Construction Projects David Liu and Huang Yan In this work we are concerned with assessing international railway construction projects in real options approach (ROA). The case is the railway construction project conducted by a Railway Construction Company in 2009, in which the company had produced an enormous financial loss. We used the mean-reverting model to evaluate the real option in the project, and innovatively, we propose to adopt the present value of the project normalized by both the length of the constructed railway and the construction time as the underlying variable which follows a stochastic mean-reverting process. This idea allows us to evaluate the real options using Monte Carlo simulation. The paper provides the method and ideas for contractors and project managers who would seek to minimize risks in decision analysis. Key words: Real options, Decision making, Mean-reverting process, Railway construction _______________ Dr. David Liu and Mr. Huang Yan, Xi’an Jiaotong-Liverpool University, Suzhou 215123, P.R. China.
