Description: The paper presents functional model of information technology for availability assessment of safety-critical instrumentation and control systems. The information technology shows the process of I&Cs availability assessment using Markov-chains with implementation of metric-based analysis of the system model. The result of such analysis aims to eliminate the non-effective techniques, method and tools for model solution.
