Systems engineering – synergy of science, knowledge and applied technology

The following paper presents the theoretical foundations and selected practical applications of systems engineering. To begin with, the concept and subject of systems engineering is defined and embedded in the family of systems sciences. It also outlines the systems approach methodology applied in the systems engineering and the strong interdependencies that exist between systems theory and the practice of building systems applications. The matter of presenting selected categories of systems engineering, such as requirements engineering, environmental engineering, safety engineering, medical engineering, genetic engineering, management engineering, financial engineering, software engineering and social engineering was pivotal element of the paper. The paper has a form of a synthesis and an overview and contributes to further discussions within the framework of promoting a universal systems approach in the praxeological disciplines of the different categories of technical and non-technical, tangible and intangible, but always innovative and creative engineering.
