Risk management is a complex process and its main aim is to identify the areas with high level of risk, to define it, assess it and establish the measurements that either eliminate the risk or decrease it on the demand level (Buc,Kliestik, 2013). In the case that no data are available on which one could estimate the probability distribution, we rely on experts estimations if we want to determine the risk factors distribution. In such cases, as stated by Hnilica and Fotr (2009) only the following types of distribution are to be used: Uniform distribution- can be used only if the estimations of maximum and the minimum possible values are known. It disposes of a high uncertainty rate which is the same for all values.
