Holistic dynamics and subsystem modelling: principles

Holistic dynamics of systems is a new and important in the context of a system's life cycle. This paper develops the concept of holistic systems. It discusses the modelling of short (fast time) term (dynamics) and long (slow time) term energy processing (evolution) during the life of the system, and the incorporation in the holistic model of the system thus the holistic model of the system describes the system evolution as well as its dynamic behaviour. System decomposition methods are discussed. The paper presents the principle of holistic modelling of system decomposed in subsystems and their energy transformation in particular.
