For engineering purposes (i.e. also for ITS) the classical approach: GTS - General Theory of Systems which is based on ideas of Karl Ludwig von Bertalanffy [1] and his co-workers is probably the most beneficial. A purposeful source of knowledge on the internet is [2]. An excellent review of fundamental Systems ideas is provided in the works of G.J. Klir [3, 5]. Both innovative and thorough insight into the engineering utilizations of Systems ideas is presented by J. Vlcek [4].
