Support of functional safety management of software and hardware complexes based on system archetypes

This paper describes an approach focused on the construction of mathematical models that illustrate from different angles typical situations arising in the implementation of software projects. The basis of the approach is the analysis of projects for creating hardware and software complexes as a kind of subject-centric systems. This lays the groundwork for scientific adaptation of well-known approaches, used for researching complex systems of a different nature, to the field of functional safety of hardware and software complexes. In the publications, typical problem situations that occur in managing complex systems of different nature are regarded at the declarative level and called system archetypes. From a practical point of view, the limitation of system archetypes is that they represent situations only at a qualitative level. They do not depict the structure of the control system and the parametric dependencies of direct and cross-links that take place in the control system. In this paper, several examples of constructing structural models corresponding to different system archetypes are considered. For the generation and analysis of alternatives for resolving situations, methods for converting archetypes to the form of structural and mathematical models are proposed. The range of applicability of the proposed approach includes projects of medium scale, i.e. mass-produced projects.
