STRUCTURAL ELEMENTS OF CALCULUS OF SYSTEMS AS FUNCTIONAL OBJECTS
The article discusses the basics of the original formal apparatus – the calculus of systems as functional objects. Calculus is considered in the context of its use to formalize the procedures of system-object analysis of weakly formalized systems. The basic concepts of calculus are considered, such as: a system-object model, a node object, a streaming object, connections of a system-object model, structural components of streaming and node objects. An example of an abstract system and its formal representation by means of calculus is considered. In addition, an example is given of using the method of system-object simulation modeling to build a model of a combined channel signal generation system in order to study its level of resistance to interference.
