(.): We suggest several efficiency metricsfor investment projectsusing borrowed money (stability degree, lowest loan repayment period, net present value, internal rate of return) with loan structure explicitly accounted for in formulas. They allow for considering a problem of joint selection of an investment project and a loan structure. We also derive the analytical expressions to calculate performance indicators under uncertainty using the arithmetic of LR-typefuzzy numbers. Possible applications include investment analysis. - : 3821, : 1345, : 16. |
