The present paper deals with the implementation of risk analysis in engineering economic
problems, using Monte Carlo simulation. The paper consists of two parts. After a short introduction
about risk analysis methods used in engineering economic problems, the first part discusses
the role of simulation, especially Monte Carlo simulation, in risk analysis and presents an
extended review of studies, using either statistical techniques in general, or specifically Monte
Carlo simulation in risk analysis. In the second part of the paper, we construct a model of a Monte
Carlo simulation for the appraisal of a potential investment with uncertain annual revenues and
costs, using Excel Spreadsheets and Visual Basic. The implementation and use of the model is
demonstrated with a numerical example. The results obtained show that Monte Carlo simulation
can prove a valuable technique in the decision making for the evaluation of a potential investment.
