“…The research [17] addresses the problem of using machine learning methods to provide LCA solutions. The general hypothesis is this: LCA, backed up by machine learning and based on dynamic data, paves the way for a more accurate LCA, supporting decision-making throughout the Favi, C. [18] suggest including TRL and production readiness level (MRL) when evaluating the life cycle of new technologies as an indicator of technology maturity. The research works [19,20] define the problem of the functionality of the observed system.…”

Standardization is essential for innovation (on the impacts on design, manufacturing, and operation processes) and its dissemination, both within a country and internationally. A phenomenological information model has been developed for the system of standards, which will be used as an information base for integrated quality management systems, environmental safety, and energy saving depending on the type of products, requirements of technical regulations, and conformity assessment procedures. Phase portraits of the life cycle system of complex products were constructed, and a general expression for the Lyapunov exponents characterizing the overall behavior of the dynamic system in phase space was obtained. The presence of particular areas to which, regardless of the initial conditions, all phase trajectories rapidly evolve has been established. The critical conditions for the control parameters were found. A diagram was constructed that determines the stability of the system states of the life cycle of complex products. It was found that the processes of the life cycle of complex products are carried out in two stages: in the first, there is a rapid evolution of components and parameters of technical and software tools, as well as energetic elements of functional subsystems, which is reflected in a specific attractive section of phase portraits, in the second, further slow development along it.

The paper proposes a model for the life cycle of physical assets that includes the maintenance policy, because it has direct implications on the equipment’s Return On Investment (ROI) and Life Cycle Cost; the developed model can be applied to any type of physical asset. The model is called Life Cycle Investment (LCI) instead of the traditional Life Cycle Cost (LCC). The paper proposes a new methodology based on the modified economic life cycle and lifespan methods by including the maintenance policy using maintenance Key Performance Indicators (KPI), namely Availability, based on the Mean Time Between Failures (MTBF) and the Mean Time To Repair (MTTR). The benefits (profits) that result from the asset’s Availability must be balanced with the initial investment and the variable maintenance investment along its life, which has relation with the maintenance policy and the ROI.

“…Because arc welding is the most spread welding technology in industry, many research works exist dealing with a corresponding life cycle assessment for such processes. In this relation, Favi [ 18 ] compared a wide range of arc welding processes. Based on a functional unit of 1 m of weld seam length, the welding of 25 mm thick plates of mild steel was considered.…”
