Resumen
The subject of the study is models and methods of construction and implementation of non-linear strategies for managing infrastructure programs. The purpose of the research is to analyse the current state of goal setting and to identify effective strategies for implementing programs with changes in developmental directions at bifurcation points in the environment, challenges, risks and opportunities. The resilience of program development in the face of rapid and critical changes in the external and internal environment can be ensured by effective models and methods of targeting and achieving infrastructure programs in the conditions of critical changes in the external and internal environment. The objectives of research on infrastructure program management are to build non-linear models and methods of strategic management, taking into account the dynamics and adequate response and ensuring compensation for changes in the environment. The methods used by the infrastructure manager forecasts the development trends of the environment in the short and long term. The result of the study is the formulation of the mission and the definition of a non-linear strategy for the infrastructure program, which is based on the concept of evaluating its value in the way it is presented by the customer. This allows interested parties to communicate as efficiently as possible and, where necessary, to agree with the customer on changes and additions to the infrastructure program. Conclusions. The context analysis is considered as a methodology for comprehending and presenting a holistic picture of the infrastructure program. This analysis is used to interpret the mission and strategy if the interoperable multiple values of the infrastructure program are expressed in abstract terms. Uncertainty of this type causes numerous losses and additional costs. Misunderstandings arise from the fact that the mission context and nonlinear strategy cannot be fully disclosed due to the underdevelopment of relevant models and methods. Therefore, basic rules for their interpretation are offered to describe the mission and strategy of the infrastructure program.
