T1 Mathematical Modelling in Normative Development Planning YR 1976 FD 1976-01 SP 104 OP 106 AB The paper presents an approach for modelling long-term development of complex economic systems. Concerning management of a complex system one has to single out the following three main stages of research: goal formulation, calculation of planned or ideal system’s development strategy (trajectory), and selection of additional controls or changes of the preliminary chosen controls which may allow one to compensate influence of certain random factors or factors which were not taken into account at the preliminary stage of analysis.
