Abstract

This paper deals with the Mean Time to System Failure (MTSF), steady-state availability and profit analysis of a two-dissimilar-unit cold standby system with considering human failure. The proposed system has been investigated under the assumption that each unit works in three different modes: normal, partial failure and total failure. The system suffers two types of failures: via; unit failure and human failure. Failure and repair times are assumed to have exponential distributions. Using linear first order differential equations, the system characteristics are obtained. Finally a numerical example is presented to illustrate the theoretical results.
