Abstract. The criterion according to which the plans of a research organization can be optimized with respect to modelling R&D management consists in maximizing such profits as the envisaged results of research investigations may practically achieve throughout their application. The constraints are the available time and financial resources of the research organization, any investment outlays to be made by the beneficiaries and the time and money expenditures required for the solution of each individual theme competing for inclusion in the investigation plan. Mathematically it is a linear programming problem with bivalent variables. Because of the reduced size of the system a dynamic programming approach is also possible.
