Abstract: A method for managing a life cycle of a complex engineering facility, comprising several steps. The steps include forming a facility structure of the facility; selecting constituent elements of the facility structure and the relationships between the constituent elements and a location of each of the constituent elements in a decomposition structure of the facility; forming a linked array of requirements related to the facility and to processes of implementation of the requirement for the facility; planning and accounting for the requirements in accordance with the structural decomposition of the facility, the requirements being assigned a certain status; and forming databases intended for storing an associated array of information about the constituent elements of the facility, the associated array of information comprising at least a plurality of documents related to design data and/or to supply and procurement data and/or to pre-commissioning data and/or operation data and/or facility configuration data.

Abstract: Automated control methods used to manage the life cycle of complex engineering facilities such as nuclear, thermal power, and hydroelectric power plants. The invention can be applied at the design, construction, operation and disposal stages of such facility. The system of life cycle management ensures configuration management, identifying and documenting the characteristics of structures, systems, and elements of a facility, and ensures that changes to these characteristics are properly designed, verified, approved, released, implemented, tested, recorded, and reflected in documentation.
