Theoretical results not always give an unambiguous answer regarding the preference of
using the indices of IT project investment efficiency. To complement some of such results,
the Net Present Value (NPV), Profitability (PI), Equivalent Annual NPV (EANPV), Equivalent
Annual PI (EAPI) and Internal Rate of Return (IRR) indices are researched by computer
simulation. In this aim, the respective general problem is formulated, a model of comparative

Theoretical results not always give an unambiguous answer regarding the preference of
using the indices of efficiency of investment in IT projects with equal lives. To complement
some of such results, the Net Present Value (NPV), Profitability (PI) and Internal Rate of
Return (IRR) indices are researched by computer simulation. In this aim, a model of
comparative analysis of projects with equal lives is defined and the SIMINV application is
made up. Using SIMINV, the percentage of cases when the solutions, obtained according to …
