Ontological analysis of defects at the designing of hardware-software complexes

The article focuses on the analysis of defects in hardware-software complexes as an integral part of the functional safety management of complex systems. The analysis of unintentional defects locations that could affect the functional safety of hardware-software complexes is made. An approach to the concept of "defect" as a multidimensional system, described its projections: impact on stakeholders, technological, managerial is proposed. The classification of characteristic defects for software products and projects are shown. A system and mathematical models of software products and projects as a basis to identify possible locations of defects is described. The role of the subjective component in the designing of the components of hardware-software complexes is demonstrated.
