The article deals with the feature’s projects portfolio formation of head enterprise that produces high-tech products. Methods the projects portfolio formation are considered: mathematical, simulation and economic-statistical. The factors that influence the choice of the model are illustrated.It is proposed to carry out research on the basis of creation complexes ofinterrelated, multi-level models and optimization-simulation approach. Themeans of implementing this approach are human-machine iterative,interactive procedures. To find the optimal solution by the decision maker,procedures should be based on the identification of the main goals andpreferences used in the creation of an optimal of the project portfolio, thestudy of a set of acceptable parameters and actions.  The head enterprise is considered as a complex system described by severalmodels, to which the control scheme with direct and feedback is applicable,where:  functional breakdown of the process of forming the projects portfolio into separate blocks justifies the use of multi-level modeling of a complex production system;  in long-term planning and forecasting, it is necessary to solve both the direct problem of system consequences for a given “input”, and the inverse problem of planning, which has a significant spread of output parameters. In order to optimize the method, it is proposed to create iteration- optimization analytical models using the two-point boundary value method, including planning from the achieved and planning from the final result. Indicated the advantages of using a specialized mathematical apparatus inthe formation of the projects portfolio.
