Abstract

Models and mechanisms for project portfolio management, constantly generated by the IT service provider and designed to optimize IT processes of IT service life cycle stages are the subject of this article. The service improvement plan is formed from the project portfolio and is aimed at achieving critical indicators of IT services market success relevant for the current period. Two linear and one nonlinear models of the problem of forming a service improvement plan were considered. The criteria chosen for task optimization are absolute and relative value of the complex IT process efficiency indicator. Problems take into account the investment costs on implementing projects and changing the operational costs on functioning of optimized IT processes. All the problems were solved with the use of network programming methods.
