This paper discusses the problem of capital budgeting in the situation where only some model parameters are well described by their past data and therefore are specified by random variables, whereas the remaining model parameters can hardly be predicted by historical data and therefore they are...

This paper presents a method for evaluating the risks in a situation where parameters in the calculation are expressed in the form of dependent fuzzy numbers and probability distributions. The procedure of risk estimation combines stochastic simulation with the execution of arithmetic operations...

Fuzzy arithmetic seems to be a well-developed and well-formalized branch of fuzzy sets theory. Nevertheless, there are some problems with its practical implementation. In practice, one can very often encounter the question of how to calculate the value of an arithmetic expression when its...

Risk accompanies every economic decision. Investment decisions are burdened with particularly great risk. Quantification of risk belongs to most heaviest tasks in risk management of the investment project. Traditionally, probability distribution was being utilized for the description of the...
