The aim of the article is to present a method of project portfolio management for the regional development of dual education under conditions of uncertainty using expert methods. In the project portfolio management standard, portfolio formation is represented by a group of alignment processes, but their practical application in a specific subject area remains at the discretion of the developer. For the design and development of software systems, visual process models are developed for a specific subject area. The article presents the development of a complex system of dual education through the formation of a portfolio of projects. The data obtained allowed to determine that the portfolio management methodology can be successfully implemented in Ukrainian dual education. To improve the processes of portfolio management, a practical implementation of the processes of portfolio formation in the IDEF0 notation was carried out. A simplified algorithm for forming a project portfolio has been developed, which allows increasing the speed of response to changes in portfolio managementin educational sphere. The proposed solution of the educational system development through portfolio using expert methods that are distinguished by the application of the Pareto rule forbuilding a scenario for the system development. On the basis of the developed methodology for forming a portfolio of innovative projects, the process of optimizing the efficiency of the portfolio of innovative projects with determining their individual priorities is studied on the example. The application of the developed procedures for planning the portfolio management of the dual education system in the central region of Ukraine is demonstrated. The results obtained have made it possible to make sure that the system development management in conditions of incomplete information covers the areas of process management, and helps to minimize the impact of uncertainty on the efficiency of the portfolio of projectsimplementation.
