The LIFECON Life-Cycle Management System (LMS) is a European model of a predictive and integrated LMS for concrete infrastructures. It is generic in nature and will be suitable for different categories of structures, from buildings, bridges, and nuclear power plants, to lighthouses. LIFECON LMS has two planning phases: long term and short term. The system is also divided into three levels of structural hierarchy: component and module, object, and network. The component- and module-level system addresses structural components such as beams and columns and their combinations in modules. The object-level system deals with complete structures or buildings. The network-level system treats networks of objects such as stocks of bridges or buildings. The LIFECON LMS is capable of considering the many requirements and aims involved in decision making. Besides a structure's observed condition and evaluated urgency of repair, many other requirements should be taken into account, such as life-cycle costs, user costs, minimum requirements of structural performance, structural risks, traffic and other operational requirements, aesthetics, environmental risks, and ecological pressures. Thus, the method of multiple-attribute planning is applied on all hierarchical levels of the system. The life-cycle analysis and optimization module involves the data applications for studying the economy of the life cycle and cost-effectiveness of optional maintenance, repair, and rehabilitation strategies. Alternative strategies are compared as life-cycle activity profiles over a defined time frame. The purpose of life-cycle analyses is to find the optimal activity profiles to reach the targets.
