The methodology of risk calculation for project network techniques is presented. Development and research work is … connected with uncertainty and risk. Many models for engineering design process are described in literature but it is necessary … measurable numbers. Transitions from precise probabilities to imprecise probabilities in probability theory are a form of …

In the classic Markowitz model, risk is measured by the return rates variance. However, equal treatment of negative and … positive deviations from the expected return rate is a slight shortcoming of variance as the risk measure. Markowitz defined …

The widely used risk measures as standard deviations and value at risk do not always reflect risk preferences … accurately. To overcome this problem we show coherent risk approach. For making the overview of the problem of risk measure we … propose a coherent risk measure approach. We started from the definition of risk (market and other) and we took a close look …
