Project Portfolio Construction Using Extreme Value Theory

Choosing proper projects has a great impact on organizational success. Firms have various factors for choosing projects based on their different objectives and strategies. The problem of optimization of projects&rsquo
risks and returns is among the most prevalent issues in project portfolio selection. In order to optimize and select proper projects, the amount of projects&rsquo
expected risks and returns must be evaluated correctly. Determining the relevant distribution is very important in achieving these expectations. In this research, various types of practical distributions were examined, and considering expected and realized risks, the effects of choosing the different distribution on estimation of risks on construction projects were studied.
