Models of content management of infrastructure projects mono-templates under the influence of project changes

Abstract

A thorough study of the process of managing the content of infrastructure projects monotemplates under the influence of project changes was carried out. During the study, was carried out a systematic analysis of the implementation processes of infrastructure projects, programs and project portfolios. A model of formation the modification factor of changes in the content of infrastructure projects, programs and project portfolios at the planning stage was developed, which made it possible to identify the process of modification the content of the infrastructure project under the influence of changes. Based on the systematization of the dependence matrix was constructed a graph of influence dependences of modification factor of changes on different levels of projects, programs and portfolios of infrastructure projects during the life cycle. The study of the subject area allowed to expand the terminological base of project management, programs and portfolios of infrastructure projects by formalizing the concept of "changes in infrastructure projects, programs and project portfolios. The model of content management of infrastructure project mono-template under the influence of project changes is presented. The model is formed on the basis of application of DSR mono-template of infrastructure project and taking into account 5 stages of infrastructure project content management. 4 classes of deviations of infrastructure projects content under the influence of project changes at the planning stage are formed and their quantitative range of distribution is presented. The practical formalization of the developed models with the representation of the corresponding mathematical dependences was carried out.
