Conceptual model for managing the phases of implementation of infrastructure projects and programmes in the post-war period

The outbreak of Russia's full-scale invasion of Ukraine has caused significant human, economic, and political damage, as well as destruction to infrastructure. However, in the future, all losses incurred should be recovered. Therefore, creating models to manage infrastructure projects is still important, especially in the post-war environment of Ukraine. The purpose of this study was to build a model that would allow for the highest management efficiency in the implementation of infrastructure projects in the post-war period and to describe the possibilities of its practical application. The main methods used in the study were analysis, modelling, and abstraction. Thus, the study built a conceptual model of management of infrastructure projects and programmes in the post-war period. The study also analysed the current theoretical framework for infrastructure project management and highlighted the issue of substantiating the parameters of infrastructure programme and project products. Network models, their features and possibilities of use were described to provide a clearer picture of the project's work and more efficient resource management. The paper emphasised that infrastructure projects are often divided into two phases: construction and operation. The study also described the importance of infrastructure projects for the efficient transport of goods and passengers and their impact on the competitiveness of the transport system. This study offers a more profound insight into the specific features of managing the implementation phases of infrastructure projects, especially in the post-war period, and brings new knowledge for management in the context of building large-scale investment programmes
