The k-terminal dynamic fault trees for a system of three IoT-devices connected by a triangle are formed. Based on the fault tree a state and transition diagram is generated. This model can take into account adequately) load-sharing effects between renewable communication channels. Availability characteristics and failure causes characteristics are calculated based on Monte-Carlo simulation and comparative analysis for obtained results is done.
Aim. To develop an approach for adequately formalizing and calculating reliability using a dynamic fault tree for a two-component system as an example, taking into account the short-term mode of operation of one of the system component. Method. A k-terminal dynamic fault tree is used to formalize reliability. In this tree, the structure and behavior of the system are separated. On the basis of the tree the diagram of states and transitions of the system is developed.
