Application of mathematical modelling for choosing company's investment program

The paper presents three economic-mathematical models for the formation of the company's investment program: (1) based on the principle of guaranteed payoff (ie maximin principle); (2) based on the principle of maximizing the average expected value under predetermined up limiting of its dispersion; (3) based on the principle of maximizing the average expected value under up limiting the probability of its inaccessibility. Proposed solutions of the problems allow us to give a system estimate of the investment attractiveness of the enterprise which can be used in selecting an effective investment portfolio based on risk appetite of decision makers.
