"Systems Engineering with SysML/UML: Modeling, Analysis, Design"


Figure 1.5 shows the superior cross-section functionality of systems engineering.
In particular it shows that systems engineering does not replace software
engineering. It will interfere with the matters of software engineering only to the
extent as requirements are given to bring about the best possible integration in
the overall system.
1.2.7 Marginal Notes
General systems theory was founded by the biologist Ludwig von Bertalanffy. He
carved out common features from different fields of knowledge and described
them in his book [58]. In the sense of general systems theory, technical systems
are only one of many possible fields of application. Others would be, e.g., economics,
sociology, and psychology. Human social systems could be seen as a system
just as well as the world economy, or an automobile. We will only look at systems
made by humans in this book.
This means that general systems theory is on a very abstract level.
Transferring it to a concrete fi eld of knowledge, we can derive many important
and specifi c tools and methods.
