The topological functioning model (TFM) of the system could be automatically transformed to behavioral specifications, e.g., UML Activity Diagrams, and BPMN diagrams. However, the TFM lacks a formal definition and specification of topological cause-and-effect relations. This paper addresses this challenge by using an inference means suggested by classical logic, namely, notions of necessity, sufficiency and logical operators. The result could be applied in order to reduce human participation in transformations, as well as to verify results of analysis of the system.
