Summary: The eld of research in this dissertation is concerned with structural study of open/closed quantum systems, especially regarding bipartite structures. Using entanglement relativity rule, it is demonstrated quantum correlations relativity, as a generalization toward case of mixed bipartite states. As a consequence of quantum correlations relativity, it turns out that so called Nakajima-Zwanzig projection method has limitation: for alternate structure the building of proper master equation must be started from the scratch. On the other hand, regarding \the appearance of a classical world in quantum theory", structural analysis bring to conclusion that environment is choosing the most classical structure: classicality is a matter of the distingushed composite system structure. Structuralistic way of thinking shows as natural in theory of quantum scattering, seen as a fundamental way of interaction in many-particle systems. In turn, via theory of asymptotic completeness, then associated interpretation (of Kitada) it is possible to set specic view of the quantum unitary dynamics, where time is classical hidden parameter, giving rise to so called local time scheme. Analysis shows de ection from standard dynamics and novel insights into aspects of decoherence theory, non-markovianity od system dynamics etc.
