Multi-aspect modeling of situation in the functional safety control tasks of hardware and software complexes

Functional safety is a latent characteristic of hardware and software complexes (HSC) and is objectively characterized by consumer satisfaction with the HSC behavior. The paper considers an approach to solving project management problems based on the dynamic characteristics analysis of functional safety of conflict situations in the project management system. To analyze situations that arise when managing HSC projects, it is possible to use models known as system archetypes. The information essence of situations and the foundations of multi-aspect modeling are considered. The methodological basis of the research is a combination of dynamic models of parameters that characterize functional safety and structural models, corresponding to conflict situations that arise when ensuring the required level of functional safety. Examples of multi-aspect modeling of situations where manifestations of latent defects act as events are considered. As a result of the research, the information essences of situations are determined, the conceptual foundations of multi-aspect modeling of situations that arise when managing the HSC functional safety are proposed, and the basic stages of building a system of structural and dynamic models of situations at different stages of the HSC life cycle are identified. The results obtained can be used to make decisions about the advisability of making changes to the system structure for ensuring the functional safety of hardware and software complexes.
