Issue #7. Object of analysis decomposition. Formulation of functions

Issue is devoted to consideration of the basic concepts of VA used in the process of decomposition of the formation of a structural model (SM) and the formulation of its functions in the formation of a functional model (FM). In addition, the issue contains a list of possible degrees of abstraction of the consideration of the object of analysis, a list of models used by the cost engineer, and a functional model (FM) functions classification.
