Hauptzuordnungen bei Modulbildungsprozessen von Konstruktionen

New challenges in design and manufacturing preparation processes are not always heading to new designs and technologies creation, but also to satisfy wide range of needs oriented toward a particular class of technical means. Sets of constructions, named as construction families, basing on identical general system are presented in this article. For that kind of a construction family, the conversion has been proposed, to change a construction from unordered to ordered form. These conversions are made simultaneously in needs and construction domains. In modular systems creation it has been distinguished four assignments: α, β, γ, δ.
