This paper presents the results of study of the analysis of the formation of a portfolio of innovation projects based on the management of their life cycle parameters. An algorithm for forming an innovation portfolio is proposed, which includes analysis of the duration of the life cycle stages and determining the level of competitiveness of the planned innovations in the portfolio, assessing risks, and forecasting the expected economic results when implementing them. An algorithm has been developed that allows choosing the optimal set of risk management methods as a part of an innovation project, which includes identifying factors that increase and decrease the impact of a particular risk on the innovation implementation process. The proposed methods of monitoring the competitiveness of innovation projects allow assessing the competitive possibilities of an innovation project, which allows determination of the main directions for its implementation.

The purpose of this paper is the development of a methodical approach to management of the parameters of the life cycle of innovations. This approach ensures the increase of the efficiency of economic activity by intensifying the processes of innovative development of industrial enterprises. As a result of the research, the features of the processes for implementing the life cycle of innovations were determined; the system of criteria for assessing the efficiency of management of the parameters of the life cycle of innovations was developed; a management model for the parameters of the life cycle of innovations was formed; and a management mechanism for the life cycle of innovations in a saturated market was developed.
