RELIABILITY ANALYSIS OF DYNAMIC BEHAVIOR OF MULTI-STATE SYSTEMS

   A lot of systems (operating systems, database systems, distributed systems, information systems) can be described, form the point of view of reliability, like a multi-state system. The multi-state system is investigated in this paper as an object of reliability analysis. In this case, the system and its component may experience more than two states of reliability as opposed to the binary system (the system and its components are allowed to have only two possible states: completed failure and perfect functioning). The mathematical model of the multi-state system is improved. We examine the system to allow a different number of discrete states for the system and for each component we propose to apply dynamic reliability indices for investigation of this system. These indices estimate the influence upon the multi-state system reliability.
