| Popis: | The paper deals with developing and researching Markov’s models and assessing of the availability of Instrumentation and control systems which are a part of smart building automation system (BAS). It was determined that the causes of failures and unavailability of the BAS component architecture can be hardware (physical), software (design) faults, and successful attacks on vulnerabilities (interaction faults), first of all. BAS failures are related to reliability issue, attacks on vulnerabilities is related to security issue. These two reason groups are considered as elements of two disjoint sets. The paper presents the detailed analysis of the BAS architecture consisting of control (FPGA-based), communication (ZigBee) and data levels considering their faults and vulnerabilities. Besides, maintenance procedures (without, common and separate maintenance for reliability and security) are described. |
