Asset Management

Description: Asset management deals with the problem of maximizing the present value of infrastructure investments. It considers not only the benefits and immediate costs but also the useful life of facilities and its deterioration, the life cycle costs related with maintenance and repairing activities and the uncertainties associated with all this processes. The main problem in infrastructure management is defining the scale and time of the investments under conditions of uncertainty. This problem is dealt with financial options and other related techniques. Based on financial engineering applications, life cycle cost analysis is used to economically evaluate different maintenance strategies while taking into account various kinds of risks, deterioration processes, demand levels and disasters issues. In addition, in order to consider the variations of the economic and social environment, real option theory is applied to ascertain appropriate timing and sequence of infrastructure projects implementation. In the same way, different problems that have been traditionally handled independently such as project evaluation, performance-based design, project finance, project / disaster insurance and cat bonds are systematically integrated in a comprehensive asset management technology that encompasses civil engineering systems as a whole.
