Life cycle management of capital construction object with minimization of atmospheric air pollution
Introduction. The existing approaches to management decision-making in construction production give the opportunity to select options only for a certain stage of the capital construction object life cycle (LC CCO), not considering their effectiveness throughout the whole LC.
